Praveen Singh :: Full Stack Engineer

About Me

I'm a full stack engineer with over 3 years of experience building concurrent microservices and distributed APIs that power production apps at scale.

Currently at Aptia Group, I architect Go-based backend services and internal engineering tooling. Previously as a Founding Engineer at Governance Matters, I shipped distributed backends for apps with 1M+ downloads, 500K+ MAU, and a 99.99% uptime SLA.

I focus on performance, reliability, and developer efficiency — from database indexing and CI/CD automation to unit testing and containerized deployments.
