Ruby, JavaScript developer, technical polyglot with strong focus on implementing maintainable systems and attaining sustainable productivity in software development.
I know a dozen of programming languages and frameworks. The above list only depicts my technical taste and the preferred stack I use in my current projects. My primary focus is to obtain widely-applicable (including enterprise-class areas) software architecture skills, but the goal of mastery in my favored language and framework (Ruby and Rails) is still a very close second.
Ruby, JavaScript, Rails, React, software architecture, microservices, domain-driven design. Startup environment working on a system serving enterprise customers. Y Combinator W17.
Ruby, Objective-C (iOS and macOS), JavaScript development in a startup environment. Our favorite child is Tapes, a tiny and fast screencasting app for macOS.
I was a leader of web development team working on a long-term project (used by the education system and military), helped other projects with architecture and engineering advice, worked on improving general engineering quality of web development department.
Co-founder, architect, developer of real estate search engine. I architected and implemented the entire application. As the only engineer, I had to wear a lot of hats, including integrating with partner services and applications, preparing documentation for data exchange APIs and DevOps. The service in the late stage was so automated and stable that my role in the project was passive.
Teamed up with talented developers and designers to do client work with a focus on CMS systems, e‑commerce solutions, and intranet software. My role, apart from back-end engineering, was being the primary point of contact between the client and the team, gathering the requirements and preparing the specification documents, as well as bringing the majority of new projects for the team.
I was a developer and system administrator. My responsibilities involved implementing new features (in fact, I implemented the entire platform) and service maintenance, including server administration.
E-commerce platform development and maintenance. The system was responsible for handling sales of contact lenses and accessories, but it also provided an online platform for ophthalmologists to support their patients.
A number of small to medium-sized PHP and Python projects, irrelevant to my current profile.
Master's thesis: Functional concurrent programming for multi-core computers.
