IndiaWhat I'm looking for
I am a full‑stack software engineer with strong expertise in Java, Spring Boot, React.js, Node.js, and the MERN stack, focused on building scalable, secure applications. I deliver optimized backends, responsive frontends, and real‑time features that improve user experience and performance.
At iOPEX Technology I developed a secure Healthcare Patient Portal and an internal Task Management System, implementing JWT + bcrypt authentication, role‑based access, Socket.io real‑time features, Redis caching, and CI/CD on AWS to reduce response times and release cycles. In prior internships I implemented bot detection, user verification flows, and responsive front‑end components.
I contribute to open source, rank in the Top 1% at Scaler Academy, and have solved 400+ DSA problems; I seek roles where I can design resilient systems, mentor peers, and continue delivering high‑impact, production‑ready solutions.
