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 software) software architecture skills, but the goal of mastery in my favored language and framework (Ruby and Rails) is a very close second.
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 division.
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 at this point is so automated and stable that my role in the project is 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 platform maintenance.
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.
