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 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 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.
Focus
Three obsessions, one throughline: build things that hold up.
Distributed systems
Consensus, fault tolerance, and data consistency at scale the architecture decisions that decide whether a system survives 3am. Most of my scars come from here.
Artificial intelligence
LLM infrastructure and RAG that hold up in production, not just the demo.
Entrepreneurship
Build in public. Ship fast. Engineering conviction meets a founder’s obsession.
Now
Currently building
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.
Writing
From the trenches
