Experienced Ruby, Elixir, Clojure and Rust

Remote work, Russia · $4000 · More than 10 years of experience · Upper Intermediate

I have been engaged with computer science since childhood. The main part of the projects which I took part are various web services. Probably, the applications of some of them are installed in your smartphone. Backends on Ruby, Clojure and Erlang/Elixir. Have production experience with Rust for micro-services. Databases: PostgreSQL mainly, Redis, RethinkDB, Elastic, Neo4j. Variety of frontend technologies, personally I prefer Elm or ClojureScript. Or even better - do not make complex frontend and using something like fomkin/korolev, synrc/n2o, phoenix/liveview. Interested in low-level programming on C/C++, looking into the direction of Rust, Swift and Scala native. Have successful experience as a team leader, but I still prefer engineering work. One of my pet projects fully developed on Clojure ( only Clojure for all, even for CSS ) still works like a clock in hands of the new non-technical owner who bought it from me. Photography is one of my hobbies. I experimenting with photogrammetry using OpenCV library. Image analyze and objects recognition is very interesting for me. I have a good sense of UI/UX. Everything I do looks nice and neat. I looking for complex problems with calculations, data analyze. I prefer companies with a flat hierarchy, independent employees who are able to cooperate decentralized for the benefit of the project. Micromanagement, Jira, daily scrums are my stop words. I am ready to work with new technology for myself. Anyway, every year I learn something new.

Transfer of regular Rails application to API + Rich client SPA in few months. Gradually transfer IM backend from Rails+PG to Erlang+Riak right under high load without fuckups. Contribution to Clojure. My name sounded few times in some IT podcasts and videos of other developers. Work in world-famous projects from five different countries. Tasty cooking )

Small team, autonomy of engineers, not outsource, remote with regular IRL meetings.

Was working on legacy (4 and 7 years) and new projects. Also has experience in building applications from scratch. Nowadays work mostly on backend part of applications but has experience in frontend part (mostly jQuery, interested in learning JS frameworks but can't see benefits from using these for now). I also has good experience in SQL (mostly PostgreSQL), not afraid to write pure SQL requests if it is needed. Also write additional code for micro apps in java-kotlin and python I'd like to further improve Ruby and RoR skills but interested in learning new things
