about.json

A backend engineer who also builds audiences.

I'm a Java backend developer based in Gorakhpur, India, focused on shipping production systems with Spring Boot, MySQL and Redis. At skilledUp, I helped architect a learning management system that now serves 10,000+ active users, while keeping response times under 200ms and cutting database query time by 60%.

Before that, I spent two years founding and growing a content platform from scratch — taking it to 10,000+ monthly visitors and a combined audience of nearly 100K followers across Instagram and Facebook. So I think about products from both the engineering side and the audience side.

Right now I'm exploring microservice patterns with Kafka, gRPC, Docker and Kubernetes, and building KRSON — an experimental data-serialization format — on the side.

Caching hot reads in Redis before they hit MySQL is most of how query time dropped 60%.
