I build systems
that scale
and sometimes think.

Payments infrastructure at Juspay — millions of transactions, zero excuses.
Working at the edge of distributed systems and software that reasons for itself.

About

Engineer.
Builder.
Works best unsupervised.

I'm Ishan. By training, an engineer. By habit, someone who can't leave a hard problem alone.

At Juspay, I build and scale payment infrastructure that processes millions of transactions daily — designing resilient systems, optimizing for performance, ensuring reliability across distributed services handling complex financial operations.

The other half of my brain lives at the intersection of distributed systems and software that thinks for itself. I'm working at the edge of what's possible right now, which means I'm wrong a lot and right just enough to keep going.

“I build systems that handle millions of transactions without flinching. I've developed a sharp intuition for failure — what causes it, what masks it, and what it quietly costs when nobody's looking.”
Domains
01
Distributed Systems

Consensus, fault tolerance, data consistency at scale. The architecture decisions that determine whether your system survives 3am.

02
Artificial Intelligence

LLM infrastructure, RAG at scale, AI systems that don't crumble in production. The engineering behind models that actually work.

Entrepreneurship

Build in public. Ship fast. The overlap of engineering conviction and founder's obsession — making things that shouldn't exist yet.

Writing about what I learn the hard way
Systems, distributed architecture, AI in production. The gaps nobody writes about because they're too busy in the trenches.
Soon
Flagship open-source project
Something at the intersection of all three domains. Name TBD. Conviction: very high.
