  • Strong hands-on expertise with Node.js, TypeScript, PostgreSQL, and AWS
  • Proven experience optimizing code and database performance in high-volume, multi-user production environments (query tuning, indexing, caching, concurrency)
  • Demonstrated ability to design and deliver end-to-end features independently
  • Working knowledge of frontend development, with the ability to implement and extend React-based UI when needed
  • Hands-on experience using AI coding assistants (e.g., Cursor, Claude) as a core part of the development workflow - mandatory

Nice to have
