Protocol Engineer · Smart Contract Security · DeFi Systems
Rebuilt Uniswap v3 and Aave v3 from first principles. Shipped 10+ production contracts. Building a smart wallet security layer to stop hacks before they happen.
100 videos shipped · 70+ hrs live coding · 10+ production contracts
Smart wallet with real-time threat detection — stop hacks before they land.
| Phase | Focus |
|---|---|
| 01 | Exploit pattern recognition — reentrancy, oracle manipulation, flash loans, delegatecall |
| 02 | Account Abstraction (ERC-4337) — smart wallets, session keys, paymasters, validation |
| 03 | Security infra research — Blockaid, Forta, Hypernative, Tenderly |
| 04 | MVP: Suspicious Transaction Delay Wallet |
MVP Logic:
IF tx > threshold → 30s cooldown
IF wallet drains > 40% → require second confirmation
IF new contract interaction → show risk warning

Uniswap v3 — Full Reconstruction Concentrated liquidity · tick math · bitmap traversal (O(1) price discovery) · liquidityNet delta · lazy fee accounting — rebuilt from scratch with recorded walkthroughs.
Aave v3 — Full Reconstruction Supply · borrow · repay · liquidation · flash loans · interest rate models · health factor logic · liquidation thresholds — verified protocol invariants and documented security edge cases.
Decentralized RWA Banking Protocol Full-stack DeFi: lending · borrowing · staking · RWA tokenization (ERC-20 + ERC-721) · Next.js frontend · role-based access control.
Decentralized Freelance Platform (Web3 Fiverr) Escrow-based contracts · milestone payouts · DAO dispute resolution · staking mechanism.
