VIVEK KUMAR

I’m a Software Development Engineer with 3+ years of experience designing and shipping production-grade distributed systems. I focus on reliability, scalability, and production-grade architecture while building maintainable backend services.

At GeeksforGeeks, I designed a high-availability Mentorship Platform using Node.js, Django, and MongoDB, serving 5,000+ concurrent users. I implemented JWT-based authentication with Redis-backed session caching and architected a horizontally scalable system.

I architected 4 independently deployable microservices with Docker containerization and GitHub Actions CI/CD, reducing the deployment cycle time by 30% and enabling zero-downtime deployments. I also optimized database schemas and query paths—cutting API p99 latency by 40% under high concurrency and reducing redundant DB round-trips by 60%.

I build robust async and distributed components, including a sandboxed code execution engine with Docker, BullMQ, and Redis queues (10,000+ learners). I’ve also implemented a fault-tolerant async notification pipeline with 99.5%+ delivery reliability using Nodemailer and BullMQ.
