About

I am a Backend Developer with 2+ years of production experience building scalable and secure backend systems using Node.js, NestJS, TypeScript, and PostgreSQL. I specialize in designing robust RESTful APIs, implementing secure authentication and authorization mechanisms (JWT, RBAC), and developing reliable fintech transaction workflows integrated with third-party services. At Paywize Technologies, I developed production-grade APIs supporting bank, UPI, and wallet transactions. I also implemented webhook-based event handling and optimized PostgreSQL queries, improving system performance and overall reliability. Additionally, I built a full-stack Smart Bookmark Application using Next.js and Supabase, featuring Google OAuth authentication, real-time data synchronization, and secure user-specific access control with Row Level Security (RLS). I am passionate about writing clean, maintainable code and designing high-performance backend systems that deliver reliable and scalable user experiences.
