What I'm looking for

I’m looking for a backend engineering role where I can build scalable APIs, secure authentication/RBAC, and optimized database-backed services, while contributing to deployment readiness with Docker/Kubernetes and CI/CD.

I’m a backend-focused Software Engineer and final-year undergraduate at NIT Patna, with strong foundations in DSA, OOPs, DBMS, Operating Systems, and Computer Networks. I enjoy designing optimized backend systems that stay reliable under real-world constraints.

I’ve built scalable full-stack applications using React.js, Node.js, Express.js, and MongoDB, including RESTful API design with authentication & authorization and RBAC middleware. In my projects, I implemented secure file-upload pipelines, webhook-based payment integrations, and indexed MongoDB query patterns to prevent issues like double-booking and reduce API latency.

I’m also hands-on with AWS, Docker, Kubernetes (Familiar), and CI/CD pipelines, so I can contribute to both application quality and deployment readiness. I’m passionate about backend engineering, scalable system design, and shipping dependable production-ready systems.
