Sunil kumar — Software Engineer

I build backend systems that don't break when traffic spikes. Over the past 1.8+ years at Snapdeal, I've worked on the backend infrastructure powering one of India's largest e-commerce platforms — designing microservices, optimizing APIs, and making sure orders, inventory, and logistics workflows run reliably at scale. My day-to-day involves building and shipping REST APIs, working with PostgreSQL and Redis, handling async processing with message queues, and keeping systems secure with JWT and RBAC auth. I've cut production downtime by 45% through proactive monitoring and have end-to-end ownership of features that real users depend on. My core stack: Java · Spring Boot · TypeScript · Python (FastAPI) · Microservices · PostgreSQL · Redis · RabbitMQ · Docker · AWS (ECS, RDS, ElastiCache, S3) Outside of work, I've solved 600+ problems on LeetCode — not to collect badges, but because strong fundamentals make better systems. I work well in fast-paced environments, take ownership seriously, and care about writing code that the next engineer won't curse at.
