NYC, Bay Area, Kharkiv, Lviv, Kyiv · $10000 · More than 10 years of experience · Advanced/Fluent

Have been a computer geek since before it was cool. Programming for over 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, Node.js, TDD, Microservices

I specialize and have deep experience with 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. Led 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 a low-latency network service (scala), an enterprise json-api service (scala), a ruby gem, an e-commerce application (rails), a semi-anonymous imageboard (es2015), an enterprise messaging application (rails, react.js), an MVP of an addiction treatment platform (rails), a real-estate marketplace webapp (rails, react.js), an advertising platform (rails, python, es2015), a CRM webapp (rails). Presently working on real estate and asset management services (rails, node.js, 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.

** built a distributed IT structure of the enterprise, working through unreliable weak communication channels. The system works until now in the enterprises of the region; ** implemented “from scratch” backup systems and automatic “rollout” of application software updates, taking into account specific features and requirements for reliability and stability in operation in a short time. There are a number of other abilities, although I am not used to bragging. ))

First of all, I am interested in working remotely or moving to your city (with the assistance of the company in search and rent accommodation, for example, for 1-2 months after relocate). Always ready for a technical interview (if necessary). Also important: ++ Adequate management. ++ Informal atmosphere. ++ Professional development and career growth. ++ Time and opportunity to learn new technologies. I would not like to spend time if: -- there are “pitfalls” when applying for work: including many interview stages, a trial period (probation period with a lower salary) and/or a test task longer than 1-2 hours of time to complete. I hope for a long and mutually beneficial cooperation! ))
