If you have a project that you need to take to the next level or develop a new one from scratch using cutting-edge technologies but still well architectured (modular, easy to extend and reuse), you are in the right place. My versatile experience in the IT industry helps me attack problems from different angles and find effective business solutions. How exactly can I help? My previous clients have been happy with me doing: • Design for front-end apps architecture • Breakdown of the scope, then build new features in an iterative way • Write clean and high-quality code • R&D for new features and products • Analyze and rethink project requirements • Take the initiative to find another approach to solve problems • Lead development team and assist teammates An active practitioner of Software Craftsmen principles. This means that I'll be: • Actively collaborating with you • Sharing my experience and knowledge • Acting on problems pro-actively • Always striving to do better Here are some keywords that bring joy to me: SOLID, event-driven architecture, declarative programming, reactive state management. I consider only product companies (not out-staff/out-source) with fresh projects/startups. Testimonials from past clients: "Feliks is strongly commited and highly motivated technical leader. His outstanding development experience and enthusiasm influence co-workers. I was always 100% sure in Feliks's both high performance and work quality. As his manager I got thoughtful technical inputs, new initiatives and precise estimations. I look forward working with Feliks in future." "Feliks is a highly qualified developer deeply respected by colleagues. Feliks belongs to the limited number of employees who care. He cares not just about deadlines and quality of the code provided, but also about the usability and design of the developed solution. In addition, Feliks is a good team player taking responsibility for the motivation of his subordinates. It's a great pleasure to work with Feliks, as he generates ideas about the tasks beyond his personal responsibilities also."
