PreyamRao

Software engineer working across the web, AI, and systems. Currently at Lumora Social. Previously at Oracle. CS, IIT Kharagpur.

— From the desk —

Building Lumora — a Web3 social platform on Sui — and writing Move contracts for new market primitives. The work sits between distributed systems and economic design: how the chain settles, how feeds rank, how an event becomes a shared belief.

Off-hours, two threads. Aletheia, a decentralized prediction market with AI-resolved outcomes. And a sub-microsecond C++ trading engine — io_uring, lock-free SPSC ring buffers, cache-line-aligned market data.
