I have 4+ years of product development experience (and 6 years as a software developer in general, including outsourcing). I'm taking part in all stages of product development: brainstorming of the idea, setting the requirements, planning A\B test or experiment, building the software, and verifying that feature works well (both testing and monitoring metrics and KPIs) I'm involved mostly in the software part but I have experience in other business and product-related activities. Also, I have experience in finding a balance between the quality of the code and the speed of the development, which might be crucial for product development. From the technical perspective, I work mostly with Ruby/Rails and React, but also have some experience with Elixir/Phoenix.

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.
