Hello! I am Pappu Kumar, a Software Engineer with ~2 years of professional experience specializing in building backend-heavy full-stack systems. My core expertise lies in designing robust architectures using Node.js, Next.js and scaling complex applications.

I have strong experience in designing REST APIs, implementing secure authentication workflows, and integrating seamless payment gateways. My work involves handling sensitive financial data and ensuring compliance in fintech domains like loans and insurance.

Beyond the backend, I have solid frontend exposure using React and Next.js, allowing me to deliver complete end-to-end features. I am comfortable bridging the gap between database schema design and user interface implementation.

I thrive on building real-time communication systems and optimizing performance for high-load environments. Whether it's containerizing services with Docker or deploying on AWS, I enjoy the entire lifecycle of software development.
