Kelvin Boateng

I am a backend software engineer focused on building scalable, reliable APIs and real-time systems using Node.js and TypeScript. I design secure REST and WebSocket endpoints with JWT auth, RBAC, and production-ready observability and testing.

At Enyata I ship multi-tenant SaaS APIs, integrated AWS S3 signed URLs and payment webhooks, and reduced API latency by 35% through Redis caching and query optimization. I also authored 250+ Jest tests achieving 92% coverage to lower production incidents.

My projects include a horizontally scalable real-time notifications service with Redis Pub/Sub and Socket.io, a video-sharing backend with HLS streaming and signed URLs, and a freelancer marketplace with escrow and Paystack webhook handling. I have hands-on experience with PostgreSQL, Redis, Docker, and CI/CD pipelines.

I collaborate actively in Agile teams, participate in code reviews, and value clean, well-tested code. I seek roles where I can continue improving system performance, reliability, and developer productivity.
