At Deqode, I architected Spiking, a real-time blockchain analytics platform that indexed transactions across Ethereum, Polygon, and BSC at tens of thousands of transactions per second. I also migrated its blockchain data to Apache Cassandra, cutting query latency by 10x.

I built Shopdefi, a decentralized NFT e-commerce platform with on-chain inventory, royalty enforcement, MetaMask authentication, and Rarible Protocol integration. Its Solidity contracts covered NFT minting and marketplace escrow.

At Flying Flamingo India Pvt Ltd (Flam), I led an eight-engineer team building backend and metaverse systems. A NestJS and Golang microservices rewrite improved p95 API latency by 60% and throughput by 3x.

At WIN Home Inspection, I lead platform and DevOps work, including a real-time analytics platform using Apache Pinot and ClickHouse that delivers sub-200 ms p99 query latency on billions of rows. I also contribute to open-source projects including rarible/ethereum-sdk and GoArcc.
