- 🔐 I’ve spent 5+ years in blockchain space, working across smart contract development,security and the infrastructure that connects them.
- 🛡️ A big part of my work has been blockchain security, spanning smart contracts, DeFi protocols, Layer 1 and Layer 2 infrastructure, and the backend systems that support them.
- 🔎 I’ve had the opportunity to work on 100+ security engagements and alongside audit firms including BlockApex, Oak Security, FuzzingLabs, and Halborn.
- 📃 I’m comfortable working in Languages: Go, Rust, Solidity, and TypeScript/JavaScript.
- ⛓️ I can work across multiple blockchain ecosystems: Ethereum, Solana, Cosmos SDK, CosmWasm and Bitcoin
- 💊 My complete audit portfolio can be found at abdulsamijay/portfolio.
Over the years, I’ve help secure across the following domains:
- Blockchain Infrastructure: Nodes, App-chains, Protocol Infrastructure, and systems interacting with blockchains
- DeFi: Lending & borrowing, CDPs, DEXs, CEXs, order books, vaults, vesting, and staking systems
- Cross-Chain: Messaging protocols, bridges, and cross-chain infrastructure
- Wallets: On-chain and off-chain wallet infrastructure, including DKG, MPC, and key management systems
- RWA & Stablecoins: Tokenization infrastructure, stablecoin protocols, and supporting backend systems
- Cloud & Infrastructure Security: Cloud configuration, IAM, KMS, secrets management, and securing cloud infrastructure
🤖 I’m currently building and experimenting with AI-driven security tooling, including an orchestration layer for codebase analysis, auditing, and security research.
