📖

About Me

I'm a Full Stack Developer with 5+ years of experience building scalable web applications using Node.js, Express, and PHP. My journey has been focused on creating robust backend systems that drive real business results.

At FFOS PVT LTD, I've built custom search engines that doubled sales, developed 7+ ecommerce platforms with 100% uptime, and implemented systems that save 16-50 manual hours daily. I'm passionate about performance optimization, security, and creating automated workflows that eliminate manual processes.

Recently, I've been expanding into DevOps with Jenkins, SonarQube, Trivy, and Docker. I believe in building systems that are not just functional, but secure, scalable, and maintainable. Currently working on AI-based healthcare applications at NeoSOFT.
