We saw 𝟏𝟎 waterfalls, 𝟐 volcanic craters, 𝟏 glacier lagoon, 𝟏 glacier we actually walked on, 𝟐 blue ice formations that looked like something rendered by a broken physics engine, 𝟒 villages, 𝟏 city. And somewhere between all of that, a silence so complete it felt physical.

I came back different. Not because of the views because of how small everything felt. In the best way possible.

Also: I breathed. Like really breathed. Reykjavík is the 5th cleanest capital on Earth for air quality (IQAir 2024). I didn’t know lungs could feel that relaxed.

As an ML engineer I find patterns everywhere. Iceland was full of ones I didn’t expect.

🌍 𝐓𝐡𝐞 𝐍𝐚𝐭𝐢𝐨𝐧 ~400,000 𝐩𝐞𝐨𝐩𝐥𝐞, 𝐢𝐧𝐟𝐢𝐧𝐢𝐭𝐞 𝐨𝐮𝐭𝐩𝐮𝐭

394,000 people. That’s it. That’s a mid-sized European city pretending to be a country and (almost) absolutely winning at it. 5th in the world for GDP per capita (~$91k). #1 on the Global Peace Index for 15+ years straight. #1 in gender equality for 14 consecutive years, the only country on Earth scoring above 90% on the WEF Gender Gap Index. Ranked 3rd in the World Happiness Report 2024, yet consistently among the highest in antidepressant consumption globally (based on OECD data measuring daily doses per 1,000 people)

Iceland gets a lot right and it shows. But the full picture also hints that even in high-performing systems, there are deeper, less visible layers shaping wellbeing. Progress is real… just not the whole story. #SmallDataset #MaximumOutput

400k people. All descended from a tiny Viking founding population. Genetic overlap is not a theory it’s a daily risk. So they built Í𝘴𝘭𝘦𝘯𝘥𝘪𝘯𝘨𝘢𝘣ó𝘬, a genealogy app where you literally bump phones with someone before getting close, and it fires an incest prevention alarm if you’re too related. The slogan: “bump the app before you bump in bed.”

I laughed when I first heard this.

Then it becomes clear: it’s essentially a graph traversal problem with real-world consequences, turned into a simple public tool people actually use. A practical solution to a practical constraint, built because it needed to exist.

Around 17.8% of residents in Iceland are foreign nationals. The largest group is Polish citizens (~22,394), making up about a third of immigrants (32.1% of all immigrants as of January 2024).

I’m not Polish, but I live in Kraków. Seeing how large the Polish community is there felt closer to home than expected.

After speaking with locals, it usually comes down to labour demand and established migration networks. I’ve noticed a similar pattern in Ireland too.

Migration is driven less by geography and more by existing connections people tend to move along established links of work, family, and communities, rather than simply to the closest places on the map.

Nobody tells you this upfront, but a road trip there runs on apps.

• 𝟣𝟣𝟤 𝘐𝘤𝘦𝘭𝘢𝘯𝘥 — emergency GPS reporting

• 𝘔𝘺 𝘈𝘶𝘳𝘰𝘳𝘢 𝘍𝘰𝘳𝘦𝘤𝘢𝘴𝘵 — nightly KP index checks

• 𝘗𝘢𝘳𝘬𝘢 — paid parking at natural sites

• 𝘌𝘢𝘴𝘺𝘗𝘢𝘳𝘬 — city parking

• 𝘎𝘰𝘰𝘨𝘭𝘦 𝘔𝘢𝘱𝘴 — the routing backbone

What looks fragmented at first is actually a distributed system stitched together through APIs, services, and real-time data streams.

In ML terms, it’s less a single model and more an ensemble each tool handling a narrow task, together producing a robust system. #DataSystems #MLThinking

Route 1. 1,322 km loop around Iceland. Built to connect the country in a single road. Two lanes. 90 km/h limit. Most people plan 7–10 days.

We had everything mapped in Wanderlog as a 7-day itinerary.

By the end of day 2, extreme wind hit and lasted a full day strong enough that the next day had to be cancelled entirely. That forced us to compress the trip into 6 actual driving days.

After speaking with locals (and checking conditions), this is a known constraint of the system:

• in the south, ~28 m/s winds (gusts up to 40 m/s) can close roads completely

• in the north, even ~15 m/s combined with snow can do the same

Statistically, in April, a noticeable share of Ring Road itineraries (~15–30% according to traveller reports and seasonal closure patterns) experience at least one full-day disruption due to weather, which directly reduces the likelihood of completing a 7-day plan exactly as scheduled.

We still completed the circle, just under a tighter execution window than planned.

Vatnajökull is massive in a way that’s hard to process in numbers alone. Around 7,700 km² in size (roughly 8% of Iceland), with ice up to ~950 m thick and an average thickness of ~380 m. Beneath it sit multiple active volcanic systemsat least seven, constantly interacting with the ice above.

It’s also changing fast. The glacier has been losing mass steadily over recent decades, with thickness decreasing by roughly ~1 meter per year in many monitored areas (and total ice loss accelerating in warmer periods).

In simple terms: it’s Europe’s largest ice mass, but not a static one.

I walked on it. Touched ice that started forming long before humans left Africa. It didn’t feel like a landmark it felt like time compressed into something physical.

Some things aren’t really “data points.” They’re just hard to fit into any model.

Iceland sits directly on the Mid-Atlantic Ridge. The North American plate drifts west, the Eurasian plate east. The result: the land slowly expands by ~2 cm per year.

Over deep time, this is not static it’s divergence. The system is continuously updating, just at a geological learning rate.

Nothing is fixed. Not even the ground.

The tallest building in Reykjavík is the church. Hallgrímskirkja. 74.5 meters. Designed in 1937, construction started in 1945, finished in 1986. 41 years. In tech we complain about a two-week sprint running long.

The city runs on 100% renewable electricity 70% hydro, 30% geothermal. 90% of central heating comes from geothermal hot springs piped directly into buildings. Switching to geothermal saved Iceland an estimated $8.2 billion between 1970 and 2000 alone. And the air WHO PM2.5 compliant, top 5 cleanest capital globally.

I kept taking deep breaths just because I could. #GreenCompute #SustainableInfrastructure

Simple: they import almost everything. Remote North Atlantic island, 400k people, small market, oligopolistic retail, high import tariffs. Groceries run roughly double what you’d pay anywhere else in Europe. A coffee can hit €7. A basic dinner for two? Budget €80 minimum.

The exception is energy. Geothermal and hydro make electricity and heating almost free by comparison. So the cost model is clear: you pay for everything physical, almost nothing for power.

2.26 million tourists visited in 2024. That generated $4.2 billion roughly $440 per tourist per night. Tourism is now ~40% of Iceland’s export earnings. They didn’t market themselves. They have volcanoes, glaciers, and northern lights. And that’s enough. #CostModeling #BusinessIntelligence

This trip was a dataset. A weird, beautiful, humbling one.

Genealogical graphs solved by a phone bump. A glacier formed before our species existed, melting in real time. A nation of 400k people quietly topping every human development index while the rest of us scale to billions and still can’t figure it out.

I left Iceland thinking: small doesn’t mean limited. Sometimes it means everything’s just closer to the surface. The data. The ground. The ice. The people.

• Thanks to my friends for making this happen—we drove every kilometer together. Worth every one. ✈️📊

• Thanks to Nori, our guide in Reykjavík, for sharing so much about the city and its history I highly recommend his walking tour https://citywalk.is/

• Thanks to my tattoo artists (Icelandic, Polish), who gave me a more grounded, almost underground perspective of Iceland in our conversations

• Thanks to all the Greeks we met along the way sharing stories about Iceland, travel, and places worth going next made the experience even richer

• Thanks to the Icelandic people for their openness and hospitality wherever we went

And finally, thanks to Iceland itself for such a unique experience I came back calmer than I left

🧬 𝗢𝘃𝗲𝗿𝗰𝗼𝗺𝗶𝗻𝗴 𝗦𝗶𝗻𝗴𝗹𝗲-𝗠𝗼𝗱𝗮𝗹𝗶𝘁𝘆 𝗟𝗶𝗺𝗶𝘁𝘀: Traditional models analyzing only EHRs miss critical genetic context. The latest foundational models are directly integrating Polygenic Risk Scores (PRS) with longitudinal EHR sequences, significantly improving predictive accuracy for complex conditions like type 2 diabetes and coronary artery disease [1].

🧩 𝗨𝗻𝗶𝗳𝘆𝗶𝗻𝗴 𝗛𝗲𝘁𝗲𝗿𝗼𝗴𝗲𝗻𝗲𝗼𝘂𝘀 𝗗𝗮𝘁𝗮 : As illustrated in 𝘍𝘪𝘨𝘶𝘳𝘦 2, multimodal architectures now use cross-attention mechanisms to structurally fuse static genetic attributes with dynamic, time-series clinical events into a shared latent space [1, 3].

🚀 𝗘𝗻𝗵𝗮𝗻𝗰𝗶𝗻𝗴 𝗗𝗶𝗮𝗴𝗻𝗼𝘀𝘁𝗶𝗰 𝗣𝗿𝗲𝗰𝗶𝘀𝗶𝗼𝗻 𝘃𝗶𝗮 𝗠𝘂𝗹𝘁𝗶-𝗔𝗴𝗲𝗻𝘁 𝗦𝘆𝘀𝘁𝗲𝗺𝘀: We are moving from single models to collaborative networks. Architectures now utilize specialized agents that debate and verify findings across multi-omics and unstructured EHR data to prevent hallucinations and improve diagnostic reasoning [4].

🛠️ 𝗔𝗱𝗱𝗿𝗲𝘀𝘀𝗶𝗻𝗴 𝗗𝗮𝘁𝗮 𝗦𝗶𝗹𝗼𝘀 𝘄𝗶𝘁𝗵 𝗠𝗖𝗣 : Standardizing diverse data is the prerequisite for agentic tool use. 𝘍𝘪𝘨𝘶𝘳𝘦 3 outlines the traditional OHDSI ETL stack (White Rabbit/Usagi) used to map clinical data into research-ready OMOP structures. In 2026, the breakthrough is that agents now use the Model Context Protocol (MCP) as a secure ‘handshake’ to interact with these standardized repositories in real-time [2].

💊 𝗔𝗰𝗰𝗲𝗹𝗲𝗿𝗮𝘁𝗶𝗻𝗴 𝗗𝗿𝘂𝗴 𝗗𝗶𝘀𝗰𝗼𝘃𝗲𝗿𝘆 𝗨𝗻𝗱𝗲𝗿 𝗡𝗲𝘄 𝗥𝗲𝗴𝘂𝗹𝗮𝘁𝗶𝗼𝗻𝘀: Multimodal AI screening of complex patient profiles is accelerating clinical trials. Crucially, these pipelines are now aligned with the unified FDA and EMA “Guiding Principles of Good AI Practice”, published January 14, 2026 ensuring stringent transatlantic regulatory alignment [5].

🏥 𝗘𝗻𝗮𝗯𝗹𝗶𝗻𝗴 𝗗𝘆𝗻𝗮𝗺𝗶𝗰 𝗗𝗶𝗴𝗶𝘁𝗮𝗹 𝗧𝘄𝗶𝗻𝘀: Multimodal data serves as the cognitive engine for digital twins virtual replicas of patients. Using edge AI and federated learning, these twins continuously sync with IoT wearables and genomic profiles to safely simulate disease progression [3].

My personal perspective is that fusing multi-omics, imaging, and clinical text into cohesive, agentic AI architectures is the necessary foundation for the next generation of predictive, personalized, and preventive care.

The mapping of the human brain is entering a new era. In my new article for Όλο Υγεία, I analyze how the NextBrain Atlas, using advanced Artificial Intelligence algorithms, maps 333 brain regions and sub-regions. This tool bridges histology with MRI imaging, shedding light on micro-structures critical for diagnosing neurodegenerative diseases such as Alzheimer's and Parkinson's.🔬💡

Just as detailed mapping of brain structure opens new pathways of understanding, applied research in mental health requires high-precision tools for understanding the clinical picture.

At Klimaka NGO (Center for Suicide Prevention and Immediate Psychological Support), we are developing an AI platform with a variety of useful tools for mental health assessment, as well as educational materials for professionals. Our approach combines personalization and security, with absolute commitment to GDPR and ethics. Part of the platform will be publicly available for interested parties.

Stay tuned for more announcements!

Both mentally and physically. In good times and in bad. Life can excite you during moments of conquest, but it can also test your mental resilience during moments of illness and vulnerability. It is puzzling. We all strive to become the best versions of ourselves. We all have dreams. We all have goals. None is better than anyone else’s. At the end of the day, we are human beings. We are humans who love each other and that is the most important thing.
Celebrate small wins. Think of others before yourself, because by default, when you think of others, you end up taking care of yourself too. Let’s prioritize others, and life will find a way to prioritize us as well. Let’s celebrate our small wins. Let’s build gratitude. Let’s celebrate the small wins of our loved ones too. Because life is always about small wins. It’s always about evolving mentally or physically and growing.

In January, I was at my best friend’s house in Costa Rica. We were celebrating his new life, his new job, and time with his family. I felt more than welcome I felt like part of the family. I practiced the Spanish I knew back then, and it made me extremely happy because I could invest in local life and the local way of thinking and working. I also gave a speech at the University of Economics, which proved to me that I am capable of standing in front of an audience and speaking about something I know well. That boosted my confidence. When my mom called me and I heard pride in her voice, I became even more proud of myself.

In February, my partner came with me to Greece, and I showed her my culture. I felt proud driving my car while she listened attentively as we stood at the Temple of Poseidon. I may live in Poland, but I belong to both Greece and Poland or maybe I don’t belong anywhere. This is the paradox of living abroad. You feel both at home and away from home at the same time. But one thing is certain: the more you invest, the more present and blessed you feel. And the more you appreciate one home while being in the other.
When I finished HYROX in Katowice, my friends and my partner were proud of me especially because I was sick. And once again, I was proud of myself. Sharing moments with them is just as important as spending time alone for self-reflection.

In March, I visited a childhood friend who now lives in Switzerland. We discovered CERN together and explored nearby areas, even touching picturesque villages in France. Catching up after so many years, in a new country but with the same childhood friends, felt like a moment suspended in time. Everything felt aligned. When you give good energy and genuinely share your interests with people, life feels ordered and meaningful.

In April, I visited Greece, Singapore, and Vietnam. Singapore marked, for now, the end of my solo-travel chapter. After traveling solo to more than 30 countries and deeply investing in local experiences, I felt it was time for closure. Closure matters whether for small habits or passions that defined us for years. Proper closure is maturity.
Then came #MyQuestVietnam with Wheeling2Help: eight days with strangers in a Vietnamese village, without drama or toxicity only kindness and mutual support. Our modern lives are full of stress, materialism, and noise. This was my third time experiencing this kind of purity, and it reminded me how easy kindness actually is. The smiles of young and old locals were enough to fill my heart with joy and gratitude. I will never forget our team leader and our nightly gratitude circles, where for one hour we expressed ourselves openly.

In May, I evolved my calisthenics skills, played more tennis, and embraced life in Kraków. Kraków is a beautiful city compact enough to explore, yet vibrant enough to never get bored. A blend of preserved history and modern lifestyle.
But the most important moment was my trip with my father to Zagorochoria. Green landscapes, stone houses, slow living, healthy lifestyles. Our parents grow older, and we never know which moment will be the last. No matter the drama buy your father that gift, tell him “I love you,” take him on a trip. Just do it. If they can’t hike anymore, don’t hike. Sit with them. Drink Greek coffee. Listen. Actively listen. You have so much to learn and gain.

In June, ΛΕΞ one of my favorite artists filled a stadium of 60,000 people. An ordinary person made extraordinary by people. He speaks about social issues and touches souls. The energy in that stadium was indescribable. At some point, I realized my sister was there too fully present and enjoying it. That realization made me smile deeply. Music truly moves people, generations, neighborhoods, entire cities.
I’m grateful for the beauty of Milos and Sifnos, but even more grateful for that shared emotional moment with my sister whether she realized it or not.

July was filled with Polish summer moments, beaches, friends, and the WINNY Festival. After six years of being pescatarian for health reasons, I decided to close that chapter and transition to a more carnivorous diet. Another closure another evolution.
Between social gardens with HSBC, tennis sessions, house gatherings, whiskey cocktail bars, and Japanese restaurants, I ended the month in Greece, visiting the KLIMAKA NGO office. Contributing as an AI engineer creating ideas and implementing them from scratch fills me with childlike enthusiasm. It reminds me of life’s true purpose: being surrounded by good people and contributing with kindness to mental health and longevity.

August filled my heart with gratitude. For ten years, my university friends and I have honored a ritual: summer vacation together. Fifteen people, same nationality, different ambitions, living across eight countries. Organizing it is NP-hard but measuring its emotional value is impossible.
This year, after ten years of friendship, there was no competition only honesty. I sent a message of appreciation, and it was received with warmth. These people are my family.

In September, my heart exploded when my partner jokingly said she wants to become a Chess Grandmaster. We play every day, improving little by little. Growth mindset. Celebrate small wins even losses. Appreciate the game, the time together, the dedication, and visualize how compound effort leads to big goals.
That month also brought intense music moments Novel 729 on stage, turning pain into power. The festival “OFF the hook”, an experience that pushes you out of your comfort zone. We jumped, screamed, and released months of stored energy. Is just myself.

October is special it’s my birthday. Being born is a huge win. Why not celebrate it? Living abroad makes gathering loved ones hard, but they came. I gave them my energy, my thoughts, my care. People matter. When we’re gone, it’s not material things that remain, but memories.
Can you be alone? Enjoy coffee alone? A quiet night alone? If yes, you’re free. This birthday was unique. One lesson from years of CBT, work, and my partner’s caring nature: taking care of people is deeply fulfilling. Not for reward but because it gives meaning.

In November, I fell in love with my partner all over again in Tunisia. Living with someone reveals everything. After fights, respect and communication allow joy to flourish. Life is short. Hug after arguments. Drop the ego. Dance. Appreciate each day. Tunisia spoke for us.
This year is about stoicism using emotions as a compass between realization, thoughts, and reactions. Life is fragile. My mom had surgery, and it reminded me again: buy that gift, hug your grandma, kiss your mom. It means more to them than you can imagine. Mom, I love you.

𝐃𝐞𝐜𝐞𝐦𝐛𝐞𝐫
December is a recap month but for me, every month is a recap. “Live non-commercially.” Celebrate daily. Labels help us reflect: who we were, who we are, where we’re heading and with whom.
Family drama was resolved. For the first time in a long while, I truly felt family. Jazz Christmas nights, Wrocław’s Christmas market, Athens with my partner, and over 30 beautiful souls I proudly call friends. Health first. Kindness second. Career third. Life is short.

Life is a journey like a river. There is the past, the present, and the destination ahead.
And the beauty lies in flowing.
