DEX and DeFi protocol development
I build decentralized exchanges and DeFi protocols end to end: contracts, backend indexers, frontend and admin panel. That includes AMM contracts with liquidity pools and swap routing, on-chain limit orders executed by keepers, staking, farming and a token launchpad, indexers with a REST API and pool analytics, and a frontend with wallet connection and a mobile layout. Live in production: a DeFi hub on Taiko L2 and Arbitrum with 25 Solidity contracts, an AMM with four fee tiers combining Constant Product and StableSwap, a permissionless staking factory and a launchpad, plus a TON trading terminal with swaps and liquidity through STON.fi. Stack: Solidity, Foundry, OpenZeppelin, Rust, Next.js, PostgreSQL. From 6,000 USD, from 6 weeks.
