What I'm looking for

I'm looking to build scalable full-stack and Web3 products, especially real-time systems, DeFi protocols, smart contracts, and cross-chain infrastructure where I can own delivery from API to deployment.

I've shipped production web applications and DeFi protocols across MERN, Next.js, and EVM ecosystems. My work spans real-time systems, scalable APIs, smart contracts, and end-to-end deployment.

At NetixSol (Web3Geeks), I built Socket.IO and Redis Pub/Sub architecture sustaining under 100ms latency across 1,000+ concurrent sessions. I also optimized Solidity smart contracts to reduce gas costs by up to 80% and delivered Next.js, Node.js, and MongoDB applications serving 1,000+ concurrent users.

I built Kaspa Finance, a Uniswap V3-style AMM that reached $15,000+ peak TVL, and engineered Kaspa Bridge, the first cross-chain bridge for Kasplex Layer 2. I’ve also developed a server-authoritative multiplayer crypto betting game supporting 1,000+ concurrent users.

Previously at CodixSol and Gamica Cloud, I improved frontend performance, optimized MongoDB pipelines, modularized codebases, mentored junior developers, and delivered 5+ full-stack MERN applications. I enjoy building reliable products where responsive user experiences meet robust backend and on-chain systems.
