PUJON DAS AUVI

Software Engineer / Full Stack Developer

ABOUT ME

I turned curiosity into code. I wanted to uncover what really happens behind the scenes: how data flows, how systems scale, and how millions of requests stay seamless. That curiosity grew into a passion for software engineering, where I build the invisible systems that make everything work.

I specialize in Node.js, Express, MongoDB, and PostgreSQL, designing scalable APIs, optimizing databases, and structuring backends that stay fast under real-world pressure.

I focus not just on building systems but on making them reliable in real-world use. I use Docker, AWS, and Nginx for deployment and scalability, and continue exploring Kubernetes to automate and orchestrate infrastructure.

I focus on building maintainable, production-ready systems that solve real problems and scale with users.

Beyond the code, I write about development—sharing technical deep-dives, architectural decisions, and backend problem-solving approaches that help other developers build better systems.

For me, development is about designing systems that work reliably in real environments, handling failures, scaling under load, and staying maintainable as they grow. It’s about building infrastructure that teams can depend on, not just code that runs.

PROJECTS

Sparkle Car Wash

I developed a full-stack car wash booking web application with booking system and JWT-based RBAC. I optimized backend APIs with Redis caching, reducing latency by 97% (194ms → 5ms). I designed an admin dashboard that is fast and easy to use, achieving 10ms TBT and 0 CLS. The project delivers a fast, responsive, and user-friendly experience.

PrimeLifeFit

I developed a full-stack e-commerce platform for fitness products with secure user roles and real-time product/order management. REST APIs were built with Express, TypeScript, and MongoDB using RTK Query, following best practices. I also created a responsive admin dashboard with charts and visual insights, delivering a fast, simple, and easy-to-use shopping experience.
