Summary
Sergei Korchinskii is a Frontend Software Engineer II based in Amsterdam with a decade of web development experience and over three years in engineering management, known for delivering high-traffic, reliable frontends using JavaScript, TypeScript, and React. He has led and scaled teams across e-commerce and operational platforms, improving developer productivity, testing coverage, and reducing infrastructure costs—most recently migrating a critical payment component to TypeScript and cutting incidents. Sergei combines hands-on engineering with process improvements (day-based estimation, Jira Plans) that materially shortened cycle times and clarified delivery. He also has a track record of mentoring and promoting engineers, growing teams rapidly while standardizing APIs and QA flows. A pragmatic problem-solver, he focuses on measurable impact—error reductions, cost savings, and throughput gains—rather than abstract metrics.
