About
Engineer. Builder.
Works best unsupervised.
I’m Ishan. By training, an engineer. By habit, someone who is always curious.
At Juspay, I build and scale payment infrastructure that processes millions of transactions daily. Resilient systems, tuned for performance and reliability across distributed services handling real money.
The other half of my brain lives at the intersection of Distributed Systems, Product Design and Software that thinks for itself. I work at the edge of what’s possible right now, wrong a lot, right just enough to keep going.
Three obsessions, one throughline.
Build things that hold up.
Distributed systems
The load isn’t only human anymore, thousands of agents hit the same state at once, and the architecture decides whether it holds.
Great design
Built for two audiences now, the human reading the screen and the agent acting on their behalf. Clear semantics and structure, legible to a person, a screen reader, and a model alike.
And beyond
AI, hardware, whatever rabbit hole has me at 2am this week. Curiosity doesn’t respect categories, it’s where the next obsession starts.

Where my attention goes when nobody’s watching.
Payment infrastructure at Juspay
Scaling distributed services that handle millions of financial transactions a day. Reliability, latency, correctness.
Writing what I learn the hard way
Systems, distributed architecture, and AI in production the gaps nobody documents because they’re busy in the trenches.
