What I'm looking for

I'm looking for opportunities to build backend or full-stack products, develop scalable APIs, and contribute to automation and reliable software delivery.

I build backend APIs, real-time collaboration products, and automated testing systems. At Beehyv Software Solutions, I create Playwright, TypeScript, and Node.js automation tools that cut QA manual testing effort by 30%+ and reduce release delays by 15%.

I’ve developed reusable API testing utilities for 20+ backend endpoints and engineered 50+ end-to-end and functional test cases, improving bug detection efficiency by 30%.

My projects include DevSync, a real-time coding platform with sub-200ms synchronization for 10+ concurrent users, SecureAuth for 1,000+ simulated accounts, and ShortLink, a URL shortener with sub-100ms redirects. I work across Node.js, Express.js, TypeScript, React, Next.js, PostgreSQL, MongoDB, Redis, Prisma, JWT, and WebSockets.
