What I'm looking for

I’m looking for a team where I can build reliable full-stack systems, own performance and security improvements, and ship AI-driven automation that truly reduces manual work—within an agile environment that values thoughtful architecture and fast iteration.

I’m a Software Engineer focused on architecting production-grade full-stack systems with React.js, Node.js, Express.js, and PostgreSQL, with a strong bias toward performance, security, and maintainable design. I’ve built and modernized applications that serve real users and meet demanding government-grade reliability needs.

At Four Pillars InfoTech, I architect and maintain solutions serving 500+ concurrent users, migrating legacy PHP systems to React.js and Node.js—improving page load speed by 40% and reducing maintenance effort by 25%. I also implemented authentication systems, secure APIs, and role-based access workflows for Maharashtra Government projects (MSBTE and EMS), while collaborating in a fast-paced startup environment that included evaluating entry-level candidates.

In parallel, I’ve been freelancing as a Full Stack Developer, delivering 5+ end-to-end applications with secure authentication workflows and RBAC. I also engineered an AI-driven tender aggregation system that crawls 10+ portals and auto-categorizes tenders, reducing manual filtering time by 70%—and I enjoy using AI-assisted tools to prototype faster and cut boilerplate.
