I'm a Computer Science student at Menoufia University (Cairo, Egypt) who builds and tests EVM smart contracts with a security-first habit: checks-effects-interactions, reentrancy guards, fuzz and invariant tests, Slither, and written security reviews that state their own limitations.
- 🔨 Eight public blockchain projects, most deployed and verified on Sepolia
- 🌱 Growing my skills across the Web3 stack: Ethereum, DeFi, and decentralized apps
- 🔐 Studying smart contract security through Cyfrin Updraft
- 🦀 Just started learning Rust and Solana
- 📢 Documenting my progress through a public 90-Day Web3 & Blockchain Learning Challenge
- 🎯 Looking for junior smart contract / security engineering roles
- 💬 Always up for a chat about blockchain fundamentals, consensus mechanisms, and dApp architecture

| Area | What I use |
|---|---|
| Smart contracts | Solidity, Foundry (forge, cast, anvil), Hardhat, Remix, OpenZeppelin, ERC-20, ERC-721, EIP-2612 permit, ENS resolvers (ENSIP-10) |
| Security & testing | Slither, unit / fuzz / invariant tests, adversarial mock tokens, coverage gates, security-review write-ups, cryptography from scratch (AES, SHA-512, RSA) |
| dApp front ends | TypeScript, React, wagmi, viem, Ethers.js, RainbowKit, Privy, Vite |
| Backend | Python (FastAPI, Flask), Node.js, SQLite, MongoDB |
| Tooling | Git & GitHub, GitHub Actions CI, Vercel, Linux (WSL2), Spec Kit |
| Learning now | Rust, Solana |
- 🦀 Rust and Solana
- 🔐 Smart contract security best practices
- 🏗️ Testing and deploying contracts with Foundry & Hardhat
- 💰 DeFi protocols and token standards (ERC-20, ERC-721)
- 🔗 Blockchain fundamentals: distributed ledgers, hashing, and consensus mechanisms
