I’m a Node.js Backend Developer with 2+ years building scalable RESTful APIs and web applications from architecture to production. I focus on reliability, clean service design, and measurable performance improvements.

At TechHub, I architected and deployed Node.js/Express APIs handling 10k+ daily requests with 99.9% uptime. I optimized MongoDB queries and indexing, reducing average response time from 800ms to 480ms (40% faster), and built secure authentication with JWT and role-based access for 5+ internal apps.

I collaborate directly with frontend teams to integrate APIs using HTML5/CSS3/ES6, helping cut feature delivery time by 25%. I’ve also delivered backend systems that reduced API latency by 40% and supported high-throughput usage patterns.

I’m excited to keep building backend services that scale, strengthen security, and deliver responsive user experiences. I bring strong engineering fundamentals across Node.js, Express.js, microservices, and MongoDB, with practical tooling like Git and Postman.
