Open to work — Go Backend Developer roles
Saravana Kumar J
Backend Systems Engineer. Go, distributed systems, authentication.
Building backend APIs, distributed systems, and AI agents, shipping production platforms while constantly learning. I build from scratch to understand internals like networking, auth, and concurrency, instead of stopping at the framework.
Currently focused on
- Go
- Distributed Backends
- Authentication systems
- gRPC
- Event-driven architectures
- Redis
- Docker
- PostgreSQL
