About

Who am I?

I have been working in the IT industry professionally since 2008.
I'm Linux heavy user since 2004, spent years on Gentoo and now using Arch for around 15 years.
I started as a sysadmin and smoothly switched to being a backend developer.
Most of my development work is being done with the Ruby programming language and Ruby on Rails framework, but I'm also familiar with Python and Go languages.
I was a hobby user of yolo models for image recognition and early-on jumped on the AI wave as an early-adopter. I have experience with various tools such as langchain, llama_index, alpaca, LLaMa, and APIs from OpenAI, Anthropic, Stability AI and so on. I know how to combine them together to create a product and solve a business case or how to run them in your infrastructure (both on GPUs and CPUs).
I use AI and LLMs in my day-to-day work and activities.
Most of the time I work remotely, but I'm occasionally being hired by local companies in Warsaw, Poland.

You can hire me if you're looking for a hacker-type entrepreneur. I am open to cooperation as a fractional CTO or fractional AI officer.

Righ now I'm focused on changing the way Polish people are using electricity as a CTO at Pstryk. If you're looking for a new electricity provider, you can use my promo code MKOZAK to get 50PLN into your Pstryk Wallet.

I strongly believe all experienced people should share their knowledge with the less experienced, so if you are a beginner in the IT industry and want to meet with me over coffee to discuss your further career, drop me an e-mail

I also believe in learning from others' mistakes. Based on observations and participation in the startup scene since 2008, I'll be more than happy to share my thoughts on that matter with you.
My main focus is a combination of climate solutions, AI, and robotics, all supported by software and aimed to help humanity.

When I'm building products on my own, I publish them under the brand Enyuka Ventures.
Some of my pet-projects, that might become ventures:

  • Enyuka Network - Europe-wide LoRaWAN network, starting in Spain and Poland.
  • Enyuka City - Smart solutions for cities
  • Greenie - Autonomous hydroponics system running in a greenhouse, 100% offgrid.
  • Work in Green - Job board with offers in green tech
  • [Stealth] - way to improve electrical efficiency in buildings around Europe
  • [Stealth] - autonomous vehicles

I've also started (abandoned currently) a YouTube channel on IoT, DIY electronics, and computer vision.

Apart from strictly computer science-related activities, I'm very interested in smart cities, clean energy sources, space exploration, and autonomous vehicles (not only cars).

Occasionally I'm a speaker at various meetups and conferences:

I'm also certified Google Cloud Platform Professional Cloud Architect (GCP PCA)
