Position: Ruby on Rails Developer
Category: Ruby
English level: upper
Years of experience: 2

In my current team, I've successfully bumped ruby version in a large project (up to 1.3kk loc) 

When I was working at Czech startup I've implemented a large API handler module that was decoupled as a standalone application as an offer for clients. This module supports race-condition with 200rps and concurrent read/writes in Elasticsearch, Redis, and MySQL and it was fault-tolerance as well. I was also working on an urgent bug on the production server which was related to background processes deadlock

My current project is about an enterprise-level international product from the area of GRC (Governance, Risk Management, Compliance). Here I'm dealing with large codebases with serverless and microservices architecture using most of the AWS services via IaC(terraform) and Typescript with Ruby as server languages, and React as client language.

Freelance –– Full Stack developer
oct.2019 - nov. 2020

At the beginning of my path as a Software Developer, I developed, scaled, and deployed several projects and services for the Russian-speaking community in the Czech Republic and one of the most interesting projects was CRM for the center of insurance and foreigners support which was developed for inner processes optimization and part of the functionality was duplicated in a private telegram bot. I was actively supporting and refactoring this project by gaining new knowledge for some time then. I was mostly using Ruby / Rails stack in these projects
I'd like to work with a modern backend technology stack preferably in a small team.
