About me

Programming languages enthusiast. Love tools that improve productivity. Strive for short and maintainable code.

Functional programming, domain driven design and TDD are great ideas. Vim and Linux are awesome. Integration testing, internal tooling and deployment automation should be prioritized.

My current favorite PLs are F# and Rust.

Tech summary

Databases: Postgres, Cassandra, MongoDB, InfluxDB, ClickHouse, kdb+

Languages: Rust, Go, Python, Perl, PHP, Q.

Tech: kubernetes, helm, docker, kafka

Personal interests: F#, Rust, Elm, CI/CD, IaaC

Work summary

Worked in range of teams and roles, from solo backend engineer(design and implement Flash API from browser based game), to tech lead of 6 developers in 2 teams project(requirements, work breakdown, estimates, mentoring, cross-team communication). Designed microservices from scratch, worked with BAs and client representatives to clarify requirements.

I value code simplicity and workflow automation. Good code should be obvious to read and easy to change.
