Have been a computer geek since before it was cool. Programming for two decades, these days I do all kinds of engineering: front-end, back-end and even reverse :-) Fluent english, strong leadership and management skills.

Rails, Ruby, Ruby on Rails, Web Development, Algorithms, Automation, CSS3, DevOps, Highload, HTML5, JavaScript, Linux, Python, ReactJS, Test driven development (TDD), AWS, MySQL, Networking, Perl, PostgreSQL, Scala, Clojure, MongoDB, SQL, Agile, Scrum, REST API, Docker, Git

Majored in backend services and infrastructure of highload projects (>5M unique daily visits). Guided a team through a transition to a formal workflow, introduced devops practices, significantly improving development process. Architected and deployed a fair number of performance optimizations. Lead a greenfield project (rails and react) from discovery phase to production deployment, establishing team culture and best engineering practices (CI pipeline, pull requests, code reviews, automated style checks, etc). Developed low-latency network service (scala), an enterprise json-api service (scala), a ruby gem, an e-commerce application (rails), a semi-anonymous imageboard (javascript), an enterprise messaging application (rails, react.js), an MVP of an addiction treatment platform (rails), a real-estate marketplace webapp (rails, react.js). Presently working on advertising and real estate services (rails, react.js, python, scala, es2017, aws).

Looking for technically challenging problems, which may include, but not limited to highload devops, artificial intelligence, complex UIs, big data, low latency; mature startups, passionate product teams. Not looking for trivial, repetitive, lower-skilled occupations, outsourcing bodyshops.
