Harjot Singh Gill

I’m a Full-Stack Engineer with nearly 3 years of experience building production web applications and blockchain-integrated internal platforms using TypeScript, Node.js, React, Next.js, and advanced Web3 tooling.

At Redbelly Network, I architected and deployed a cross-chain bridging solution using LayerZero V2, wiring RBNT OFT across an EVM-7 mesh and Solana mainnet. I also designed and engineered a Uniswap-compatible DEX backend from scratch, delivering swap, liquidity APIs, and V3 specifications.

I built an end-to-end Airswap OTC RFQ pathway and an on-chain order book using Firestore, SIWE (Sign-In With Ethereum) authentication, and smart contract settlement. I led infrastructure hardening after an industry incident by auditing and re-verifying 72 directed LayerZero DVN pathways across 9 chains to ensure bridging security.

I maintain production-grade full-stack applications and data models with PostgreSQL and TypeORM, while strengthening delivery with GitHub Actions pipelines, Jest, and Playwright (70%+ test coverage across key workflows). I also contribute through practical tooling like an AI-assisted coding ruleset (redbelly-cursor-rules) and evaluated Web3 infrastructure such as Chronicle, Stork, and custom Hummingbot PMM strategies.
