About

I build the parts of a product that have to stay up — APIs, queues, sockets and the data paths behind them.

Most of my recent work sits in real-time systems: the backend behind Pronostyx, a prediction market platform, where I integrated Limitless Exchange as the execution venue — building the order-payload, wallet and market-data layer around it — plus a custom FIX protocol parser ingesting live data from Crypto.com and event-driven pipelines held together with RabbitMQ, circuit breakers and dead-letter queues.

Before that I spent two years on full-stack product work — React and Redux on the front, Node.js, NestJS and Express behind it — with a habit of chasing down slow queries and caching the right things.

I studied B.Tech at Cochin University of Science and Technology and went through Masai School's full-time full-stack program. These days I lean heavily on AI tooling — OpenAI, DeepSeek and Claude Code — as part of how I build.

Selected work

Flagship

Pronostyx

Prediction market platform · Limitless Exchange integration

The platform layer around a live prediction market. Limitless Exchange owns the orderbook and matching — my work was everything that talks to it: validating requests, building and signing order payloads, submitting them, and reconciling responses into user positions and market-resolution claim flows.

  • Six services (Next.js frontend, Express backends, data-consumer, job scheduler) synchronised over RabbitMQ
  • Custom FIX protocol parser ingesting real-time Crypto.com market data
  • Socket.IO namespaces split by auth level — public orderbook feed vs. per-user portfolio
  • Privy wallet integration: dual EOA + custodial flows on Base Mainnet
  • Circuit breakers, dead-letter queues and retry policies across third-party and on-chain calls
