The WebRTC implementation for our music platform was flawless. Sub-100ms latency globally, zero audio artefacts. He handled the entire infrastructure from scratch. Highly recommend for real-time systems.

Sudipta rebuilt our backend from a monolith to microservices in a way that caused zero downtime. Our system now handles 10x the load with the same infrastructure costs. Remarkable engineering.

As our Fractional CTO, Sudipta helped us go from MVP to Series A in 9 months. He made smart architectural decisions early that saved us enormous refactor costs down the line. A rare find.
