Experience

Hello, my name is Ivan and I'm full-stack developer since 2010.

I'm experienced developer in using ruby/rails, jruby, OOP, trailblazer, concurrent-ruby, postgresql, mongodb, elasticsearch. Took Stanford programming courses.

I'm working at Cryptopay as lead Rails developer — payment platform where merchants and consumers can transact with each other, backed by the new bitcoin payment protocol.

I took part in implementing payment services at previous positions too: banking sector, department of transport in Russia, cell-phone operators, PPS via sms/mobile apps for Saint-Petersburg's subway.

I've also designed, implemented and maintained complete newsstand solution for periodical publishers (both mobile app and backend sides).

I've started giving lectures while studied in university. Gave talks at local rails/linux meetups. I'm also lecturing Rails for beginers course at LevelUp offline.
