My biggest achievement is being consistently great in all I asked to do. I produce exceptionally high performance. If I take the task I will take 100% ownership on it starting from requirements gathering and ending the post-deployment phase. You can be sure that it will be completed in the shortest time possible still having all required software qualities.
I am looking for a part-time project with dedication 20 hours/week or less. My hourly rate is 30$/hour. Let's save our time in case you aren't ready to pay such amount of money. Thanks!

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.
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.
