Trustworthy output from untrustworthy data. I build systems that catch what's silently wrong — a dead sensor nobody noticed, contradictory records, a garbled scan, a confidently-wrong model — so it surfaces as a flag today, not a six-month catastrophe.

I use LLMs where they earn their place (development, meaning, embeddings, plain-language access to jargon-locked data) and keep them out of decisions and the data flow, which stay deterministic and verifiable. An LLM can help you find the answer; it can't be the answer.

Senior systems engineer, multiple AI cycles of judgment on what survives the hype and where it breaks. Currently turning messy Polish legal PDFs into a correctness-checked graph — the hard part is the verification, not the AI. Previously I built a legislative-notification service that ran autonomously in production for over three years before I retired it. I've written about where AI coding agents actually fail and why verification is the real work: https://walat.eu

Best fit when: correctness matters, the data is real-world-messy, and you want someone who names what doesn't work and why.

Résumé: https://walat.eu | linkedin.com/in/dariusz-walat

Email: [email protected]

Senior software engineer, 20+ years building pipelines that turn real-world events into decision-useful information — industrial control and IoT (manufacturing, ~50-person autonomous teams), large-scale product-data aggregation (5-7M products, multi-source), regulatory documents (1.5M+ documents, ~4,000 sources).

Same pattern across domains: acquire from whatever sensing the world provides, curate, structure for processing, find correlations across heterogeneous sources.

Working with neural nets through multiple AI cycles (neuroevolution and genetic programming, deep learning, now LLMs) — perspective on what survives the hype.

Currently: regulatory forecasting for Polish law, ~30K-document scale, autonomous overnight sweeps. The hard problems are turning messy real-world streams into decision-ready information, at scale, under uncertainty.

I write about where AI coding agents actually work and where they quietly fail — walat.eu/series/ai-agents-in-practice/

Best fit when the work is engineering-shaped — application/data rather than infra/SRE/Kubernetes-heavy — and the schedule overlaps EU hours.

Comfortable as autonomous IC or small-team tech lead. Domains where messy real-world data meets non-trivial reasoning are where I'm sharpest — industrial, regulatory, scientific.

Senior software engineer, 20+ years on production systems. Working on neural nets since 1996 (neuroevolution, genetic programming) — multiple AI cycles' worth of perspective on what survives the hype. Currently building a regulatory forecasting system for Polish law: ingesting statutes back to 1944, building a graph of legislation and amendments, reasoning about where the regulatory surface is moving. The hard problems are PDF → structured graph at scale and reasoning under uncertainty, not the model wrapper.

I also write about where AI coding agents actually work and where they quietly fail.

It turns out time flies fast. Over 14 years on HN.

Being there I've been exposed to some life changing things.

Thanks!

All the best in 2024!

There are Toastmasters clubs which are online only. There are Toastmasters clubs which carry hybrid online/on site meetings in many time zones.

As for learning speaking over Zoom one anecdata point: I wouldn't get my job if not for Toastmasters and later a lot of TM meetings over zoom.

Looking at the screens for many hours 5 days a week I prefer face to face TM meetings.

Swimming 3 times a week for about 45 minutes changes the body and mind.

And is a little addictive like ex. running.

Background: I've been swimming for the last few years for about 10-20 minutes twice a week and I've experienced the changes.

Switching few months ago to more intense sessions led to dramatically higher rate of the change and I start to think about the ways of sustaining this. For now I've bought the swimming paddles and this works.

SEEKING WORK | Europe | Remote

I'm redirecting my career path from industrial maintenance management to software development.

I've done, among other things, over 10 years of code maintenance and functions extensions in a live industrial production environments.

My current preferred tool set: Python, PostgreSQL, Django, Git, Docker, Linux. Now I prefer boring tools which allow me to concentrate on the problem at hand.

I'm open to other tools as needed.

My most recent project is Polish law change monitoring service available at https://unkot.pl. Access to the source code hosted on gitlab.com available on request.

In the past I've used go (golang), cython, neural networks with feedback loops running on CPUs, genetic programming.
