Summary

Personally I am passionate about programming languages in general, enjoying clear understanding about the way they work. I can help you to learn programming languages, including unconventional ones, like Lisp, Erlang, Prolog, Haskell or Scheme.

I also can help you with academic topics such as Lambda Calculus, Finite Automata (Finite State Machine), Push-Down Automata, Finite State Transducers and others.

I enjoy explaining complicated things in a simple way.

My past production experience mostly comprises from three things:

  • backend development with Ruby on Rails on various small and average-size projects
  • work on Flussonic video streaming server at Erlyvideo company using Erlang
  • frontend development using React, JavaScript

and also a wide range of other languages and technologies.

Personal project that I worked on. The idea is to record trace messages from Erlang application running live, and the visualize communication between processes as a map. It consisted from three parts: - probe code. Code that gets hot loaded into running Erlang application that starts all necessary traces and sends collected information to backend. Written in Erlang. - backend code. Collects trace information, stores it to database, maintains websocket connection with frontend code. Written in Erlang. - frontend code. Connects to backend, gather the trace info, builds a map of processes, puts them on timeline. Written in JavaScript + React. I made a working prototype and recorded a video demo, which can be found on the project link. Later I decided that its not worth continuing this project.
