Extensive experience in blockchain, 12+ years in development

Location: Remote / EU / UAE / CIS

Key competencies
- Smart contract development:
Solidity, Rust (Solana), Move (Aptos/Sui), Vyper
- Security audit:
Finding vulnerabilities (reentrancy, flash-loan attacks, oracle manipulation)
- DeFi protocols:
DEX/CEX, staking, farming, lending, bridges, NFT marketplaces
- Infrastructure:
Hardhat, Foundry, Subgraph, The Graph, IPFS, Chainlink CCIP
- Frontend:
Web3.js, Ethers.js, React/Vue + WalletConnect (MetaMask, Phantom, TON Wallet)
- Compliance:
KYC/AML integration, audit for SEC/MiCA requirements

Top project
1. DEX on Ethereum:
- Developed AMM with CLMM (concentrated liquidity)
- Processing >$500M TVL, audited by CertiK (score 95+)

2. Cross-chain bridge:
- Ethereum ↔ BSC ↔ Polygon, audited by OpenZeppelin
- Protection against attacks on validators (TSS cryptography)

3. NFT platform:
- Dynamic NFT with Chainlink VRF, trading for ERC-20/ETH
- Integration with OpenSea Seaport protocol

Audit of cases
- **DeFi protocol:
Found critical vulnerability in APY calculation mechanism (saving $50M+).
- GameFi:
Fixed a bug in lootbox randomization (Chainlink VRF misuse).
- CEX:
Audit of hot wallets + 2FA/withdrawal limits (SOC 2 compliance).

Audit process
1. Automated scan:
Slither, MythX, Echidna (fuzzing)
2. Manual analysis:
Reentrancy, access control, integer overflows
3. Economic exploitation:
Flash-loan scenarios, MEV attacks
4. Report:
PDF with PoC, recommendations, patches (Pull Request)
