I'm a smart contract developer with ~4 years of EVM experience and a production track record: I'm the core developer of a live prediction-market protocol on Arbitrum One with $136M+ TVL, 30K+ users, and 78K+ on-chain transactions.
What I can build for you:
- DeFi protocols: AMMs, staking, vesting, escrow, presales, launchpads
- NFT contracts and marketplaces (ERC-721/1155, minting, royalties, staking)
- Token contracts with custom tokenomics (taxes, buyback-and-burn, reflections)
- Cross-chain systems (LayerZero, Wormhole) and Uniswap V2/V3/V4 integrations
- Upgradeable architectures (UUPS proxies, EIP-2535 Diamonds)
- The Graph subgraphs for indexing your contract events
Why work with me:
- Security-first: BS in Cyber Security, former blockchain security researcher, 5 valid findings in a public CodeHawks audit contest
- Every contract ships with a Foundry test suite (unit, fuzz, and mainnet-fork tests)
- Gas-optimized by default: custom errors, packed storage, exact-approval patterns
- Full delivery: requirements → architecture → development → testing → mainnet deployment → verification
How we'll work: Share your idea or spec, and I'll respond with a scoped plan, timeline, and any risks I see before we start. You get clean, documented, tested code — and I'm responsive throughout.
