About

With a robust background in software engineering and team leadership, I bring over 13 years of work experience, including 7 years in IT, excelling in both backend and frontend technologies such as Java, Spring, JavaScript (ES6+), React, Redux, and TypeScript. My career highlights include leading the development of multimodule systems, notably for one of the largest stock exchanges, where I managed a team of developers, QA, and DevOps professionals. I successfully transitioned critical infrastructure components, like Kafka to Redis Streams, and significantly enhanced API performance through strategic refactoring. Additionally, my roles often involved mentoring junior team members, ensuring high code quality, and fostering a collaborative, high-standard work environment. As a Full Stack Engineer and Tech Lead, I've demonstrated the ability to swiftly adapt and lead, particularly in high-pressure environments. At DataArt, I tackled technical debt, optimized GCP expenses, and drove the adoption of clean code practices. My proactive approach in recruitment and team-building initiatives helped bring in talent that flourished under my guidance. My education in computer science and public relations, combined with international experiences in Copenhagen, Madrid, and Lisbon, have equipped me with a diverse skill set and a global perspective, enabling me to navigate and excel in various aspects of software development and team management.

Best back-end engineers I've ever worked with.

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly.”
