Uniswap V2 implementation with extensions: TWAP oracle, configurable swap fees, flash loans and slippage protection.
Governance DAO
Decentralized governance system with proposal lifecycle, three-way voting, checkpoint-based delegation and timelock execution.
Multichain Web3 Dashboard
Multichain Web3 dashboard with RainbowKit, cross-chain balances and RPC failover on Base & Arbitrum.
MPC-TSS Signer (Rust)
Rust implementation of DKLs23 threshold ECDSA protocol for secure multi-party computation signing with BIP32 support.
About Me
I'm a passionate Web3 developer with deep expertise in building secure, scalable decentralized applications. My journey in blockchain began with a fascination for cryptographic systems and has evolved into a career focused on creating production-ready smart contracts and DeFi protocols.
I specialize in Solidity development with a security-first mindset, having worked on ERC20 vaults, NFT marketplaces, AMM implementations and governance systems. I'm also experienced in Rust for high-performance cryptographic applications like MPC threshold signatures.
When I'm not writing code, you'll find me researching the latest developments in zero-knowledge proofs, account abstraction and cross-chain interoperability.
