About Osama
Full-Stack Web3 Developer | Smart Contract Auditing | Web3 Platform
Rawalpindi, Pakistan - 5:02 pm local time
I specialize in full-stack Web3 development and smart contract auditing across Ethereum, Solana, BNB Chain, Polygon, and Sui (Move). My work covers the full stack, from auditing and deploying bulletproof smart contracts to building the React and Next.js frontends that users actually interact with.
A significant part of my work is rescue projects, and clients come to me with broken DApps, vulnerable contracts, or backends that can't scale. That experience has made me a better builder because I know exactly where things break and how to prevent it from the start.
What I build and audit:
→ Smart contract auditing, ERC-20, ERC-721, ERC-1155, DeFi protocols
→ DeFi platforms, DEXs, staking, yield farming, lending protocols
→ NFT platforms, minting, marketplaces, royalty systems
→ Full-stack DApps, React, Next.js, Node.js, NestJS
→ Wallet integrations, MetaMask, WalletConnect, Sui Wallet
I keep every client updated throughout the project. If something changes, you hear it from me first, not after it becomes a problem. I work on both fixed-price and long-term contracts.
If you are building something in Web3 or need a second pair of eyes on your smart contracts before launch, send me a message and tell me what you are working on.
