Jacobklymenko
Jacob Klymenko developed foundational architecture for TechStartupClub’s UMarket repository, establishing a full-stack monorepo with an API gateway and microservices for authentication, market, and social features. He migrated the frontend to Vite with TypeScript, modernizing the project structure and improving development speed. Jacob implemented robust user registration and authentication, including Google OAuth integration via Passport.js, and ensured secure credential handling with JWT and PostgreSQL. He addressed authentication stability by replacing bcrypt with bcryptjs to prevent server crashes. His work included environment-aware gateway routing, comprehensive documentation, and tests, resulting in a scalable, maintainable platform that supports rapid onboarding and iteration.
