SYSTEMS THAT SCALE · AI THAT SHIPS

Hemant Kumar Kaushik builds systems from whiteboard to production scale.

I architect distributed systems handling tens of millions of requests a day — and lately I've been embedding LLM workflows & agentic pipelines into production backends at SEEK, OLX, and Wood Mackenzie.

Systems that scale, AI that ships.

I've spent 14 years owning systems from whiteboard to production scale — distributed microservices and serverless topologies on AWS, high-volume platforms serving 30–40M+ requests a day, and the observability to keep them honest.

My current focus is AI infrastructure: embedding LLM workflows into backend orchestration and solving the unglamorous production problems — prompt caching, vector search optimization, guardrails, and taming non-deterministic model outputs inside deterministic systems. On the side, I design and ship iOS apps end-to-end.

iOS apps I've built.

Designed, built, and shipped end-to-end — because building for scale is the day job, and building for delight is the hobby.

Let's build something.

Whether it's a distributed system, an AI pipeline, or just a good conversation about engineering — my inbox is open.
