Hi, I'm Jakub!
I'm a software developer. I started programming when I was 15. Since then, I created an Android game which was the most popular game in Poland for a while, finished my CS M.Sc. degree, and build two profitable startups. For +8 years, I worked in a few companies, but I have never been completely satisfied with it. I worked as a consultant, software developer, component lead (whatever it means), team lead, and even a CTO of a few person software house. Currently, I work on my SaaS projects, where I take care of programming and UI design even though I'm color-blind. 😎 Besides that, I'm interested in software architecture, Java, CSS styling, and ML/NLP.
