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.
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.”
Consensus, fault tolerance, data consistency at scale. The architecture decisions that determine whether your system survives 3am.
LLM infrastructure, RAG at scale, AI systems that don't crumble in production. The engineering behind models that actually work.
Build in public. Ship fast. The overlap of engineering conviction and founder's obsession — making things that shouldn't exist yet.
