About

I build backend systems in Java and Spring Boot that handle concurrency and scale under load. During my internship at C-DAC: I built a low-latency event streaming pipeline for a Linux-based proctoring system that collected system telemetry, health metrics, and exam policy violations from client machines and delivered them to the admin dashboard in near real time. I also identified communication bottlenecks in the existing architecture and implemented a Protocol Buffers–based transport to reduce end-to-end latency. Outside of my internship, I built HandyManny, a real-time labor hiring platform involving geospatial worker matching, concurrent job allocation, and state-driven job workflows. I also designed and stress-tested an API rate limiter that sustained 10K+ requests per minute. Interested in backend engineering, distributed systems, and building software that operates reliably under real-world load.

Work experience

Software Engineering Intern (Full Stack) at CDAC Patna, Aug 2025 - Feb 2026 · 7 mos, Patna, Bihar, India, • Reduced exam policy violations by 80% in internal testing by building a Linux-based AI proctoring system processing OS-level events under sub-100ms latency without degrading live exam performance. • Integrated Java with native Linux system calls via JNI to intercept restricted shortcuts at the OS level — without kernel modification — maintaining JVM stability across concurrent exam sessions.
