What I'm looking for

I’m looking for a team where I can build and harden Web3 products—smart contracts, indexers, and low-latency backend services—using strong engineering practices, security-first thinking, and room to grow into deeper crypto infrastructure ownership.

I’m a Blockchain & Backend Engineer who builds secure Web3 applications and production-grade crypto infrastructure. I develop Solidity smart contracts (ERC-20, ERC-721, ERC-1155, staking and DeFi), integrate wallets (MetaMask, WalletConnect), and implement blockchain event listeners, indexing services, and on-chain/off-chain synchronization.

I also focus on scalable backend systems for real-time analytics—aggregating market data from 12 exchanges, processing 2,000+ assets, and delivering low-latency WebSocket services and REST APIs. I design event-driven architectures with resilience and caching, write unit/integration tests with Foundry and Hardhat, and strengthen reliability through smart contract security reviews and gas optimization.
