Smart Contract Developer

I build production-level Solidity contracts from scratch - no frameworks, no shortcuts

Over the past months I've written 21 contracts covering ERC20, ERC721, AMMs, lending protocols, flash loans, proxy patterns, token vesting, Dutch auctions, and commit-reveal lotteries

I apply security-first practices on every contract - CEI pattern, reentrancy guards, pull-over-push, gas optimization, and storage slot packing.

What I can ship:

• DeFi protocols (AMM, lending, staking, flash loans)
• Token systems (ERC20, ERC721, vesting, auctions)
• Infrastructure (proxy contracts, multi-sig, access control, escrow)
