About

I'm a Tech Lead and Senior Full Stack Engineer with 6+ years of experience building scalable SaaS products using React, Next.js, Node.js, TypeScript, MongoDB, and PostgreSQL. Currently, I lead a team of 6 engineers, driving end-to-end feature delivery, code quality, performance optimization, and technical mentoring. My work has helped reduce production incidents by 40%, improve frontend performance by 45%, and reduce sprint defects by 35%. I enjoy building scalable web applications, designing APIs, solving performance bottlenecks, integrating third-party services, and delivering production-ready software. I also independently built GravityReply, a SaaS platform for Instagram automation using Fastify, Redis, MongoDB Atlas, Razorpay, and the Instagram Graph API. I'm currently open to Senior Full Stack Engineer and Tech Lead opportunities with product-focused companies.
