I can teach you all of these. How to write clean readable code, how to be dependable for your company and how to be successful in your professional life.

I started my career as a system administrator. In one point I started to work in software development company as an admin and then started to use Bash, Ruby and etc. A while later I realized that for me programming is much more interesting than just utilizing already created tools and switched my role to Junior Software Developer. After one year of work, I felt that I need more adventures and tried myself as a freelancer. Everything worked great so I started thinking about creating software development company. Voila! That's how Racoons Group had been created. In that company, I was a lead tech person, mentored juniors, made project estimations, participated in architecture planning etc. In 2016 life turned differently and company had been closed. Since that time I work in Germany as a Senior Software Engineer, focused mostly on backend and databases side.

I have a blog I write it not regularly, but honestly, I try :) My forte is to learn quickly. During hackathons and pet projects I tried to work with a bunch of technologies: Python, Elixir, Swift, React Native, Clojure. But every day and the most beloved is still Ruby (and sometimes JS)
