About me

  • Russian
  • Coding since 14y.o. Professionally since 2014
  • Extensive Ruby on Rails experience (OOP language with a great framework for startups)
  • Agile developer: TDD, CI/CD, etc
  • Experience with both cloud (heroku) and server tech (VPS on DigitalOcean)
  • Techonoly-agnostic. Quick learner
  • Polyglot programmer
  • Refactoring <3
  • Due to Russian citizenship, sadly, I require a visa to work in the UK. My last visa is still valid so I can consider short-term (1-6 months?) contracts too

Check out my blog. More articles on Medium but I'm trying to abandon it completely.

Speaking of Medium, before the pandemic I started Programming basics series to refresh my memory on some basic stuff. Had to abandon it in the end but will re-visit at some point :)

Some interests

  • Programming paradigms
  • Software design and architecture
  • #TechForGood
  • Technology, e.g.
    • Functional programming languages (OCaml, Haskell, etc)
    • Statically-typed languages in general (Kotlin, Java, C#, Golang, Haskell)
    • NoSQL (MongoDB, etc)
  • Data engineering (not much prior experience)
