some background




It is my belief that technology is the only way we can ensure a good quality of life. As engineers, we have the potential to help benefit poeple. If we can do it - we should.


Coming from photonics background, through embedded electronics and programming, to finally arrive at web-development and data science, Right now, work on the algorithm part of the new generation of medical devices.


My name is Oleg Żero /ɔlɛɡ ʐɛrɔ/ and I come from Łódź /ˈwut͡ɕ/, Poland. I have spent my last 12 years in different countires including Denmark, Belgium, Sweden and Norway (spent 8.5 years in Trondheim /ˈtrɔnhæɪm/).

I am passionate developer, total nerd and a big fun of remote work setting. My specialty belongs to solving complex interdisciplinary technical problems. Possessing over 10 years of R&D experience, I favor projects with high degree of undertainty.

Together with Mode Sensors, the company I co-founded, we work towards helping the elderly people by developing a new kind of monitoring device for monitoring against dehydration.

Key skills

My key skills are:

  • Python,
  • Machine learning (Keras, Tensorflow),
  • Web development (Azure, Django, Celery, JavaScript and React.js),
  • Statistics and physics modeling (incl. Finite-Element-Method),
  • Technical leadership,
  • Interdisciplinarity.

Navigating through uncharted territories (science-wise and literally) is actually my greatest strength. I absolutely adore creating something out of nothing. I can’t explain it. It’s just the way it is.

Why am I doing this?

Somebody once said that “if you feel like giving it all back one day, it means you’ve taken too much”. It says it all, doesn’t it?

By the way, this site was created using a static site generator, namely jekyll. It’s totally great and I recommend it to everyone.
