# Sumit Kumar on Tal

## Headline

Software Engineer \| Distributed System \| Java \. Spring Boot \. Kafka \| AWS, Docker \| Ex\-Intern @C\-DAC\|

## 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\.
