I build secure backend APIs and full-stack applications with Java and Node.js.
IndiaWhat I'm looking for
I've built production-grade REST APIs and full-stack applications, including MockMate, an AI-powered career coaching backend built with Java, Spring Boot, PostgreSQL, Flyway, and Clerk. I engineered 10+ Clean Architecture endpoints, secured routes with JWT authentication and JWKS rotation, and integrated Gemini-powered resume scoring, cover letters, mock interviews, and industry summaries.
At OctaNet Services, I shipped Node.js and Express.js REST endpoints, implemented JWT and bcrypt authentication, and improved high-traffic MongoDB query response times by 35% through compound indexes.
I also built EduTrack, a facial-recognition attendance platform with 82% recognition accuracy and sub-500ms live responses, and BookNest, a MERN e-commerce bookstore with inventory, access control, and checkout workflows. I enjoy building secure, testable backend systems across API design, databases, Docker, and CI/CD.
