About Me

Get to know me better

Hello! I'm Saroj Kumar Das

I'm a Full-Stack Developer passionate about building scalable SaaS applications and solving real-world problems through software. I work with TypeScript, React, Node.js, Express.js, PostgreSQL, Prisma, and Redis to develop secure APIs, responsive interfaces, and reliable backend systems.

I enjoy designing clean, layered architectures and implementing features such as real-time communication, authentication, caching, and role-based access control. My projects, including HireLens and TaskForge, reflect my interest in building maintainable applications that go beyond basic CRUD functionality.

Outside coding, I'm continuously learning about system design, backend engineering, and software development best practices. I'm always looking for opportunities to collaborate, learn from experienced developers, and contribute to meaningful projects.
