🔭 What I do

I architect and ship production DeFi protocols end-to-end — research, specification, implementation, audit coordination, and multi-chain deployment.

  • 🔐 $40M+ TVL secured across ~20k CLOC of Solidity on 5 EVM chains — Ethereum · Arbitrum · Base · BNB Chain · Polygon
  • 🧱 Shipped AMMs, yield-bearing stablecoins, lending & leverage protocols, staking systems, and a fully on-chain lottery
  • 🛡️ 7 third-party audits handled end-to-end, backed by deep fuzzing & invariant testing
  • 🌱 Currently leveling up in Rust

🚀 Protocols I've shipped

Protocol What it is Link
SmarDex An AMM engineered to minimize impermanent loss smardex.io
USDN Yield-bearing synthetic dollar on a delta-neutral leverage protocol smardex.io/usdn
Everything All-in-one protocol: trading, lending & leverage in a single pool everything.inc
B-Lucky A fully on-chain decentralized lottery b-lucky.gg
