About this Gig

Need a secure, scalable Solana smart contract or a complete Web3 dApp?


I am a senior blockchain engineer with 15 years of software development, 10+ years in blockchain/Web3, and 8+ years building smart contracts. I specialize in Solana programs with Rust and Anchor, plus EVM, Sui, Cosmos, and Polkadot.


I can help you build:

Solana smart contracts and custom on-chain programs

DeFi, DEX, AMM, liquidity, staking, and reward systems

Token launches, vesting, presales, and NFT platforms

Web3 dApps, wallet integration, backend APIs, and admin panels

Testing, security review, optimization, deployment, and documentation


With 2 years of smart contract audit experience, I consider security, access control, account validation, economic logic, and maintainability throughout development.


Delivery follows clear milestones from architecture to implementation, testing, deployment, and documentation. Source code is included according to the selected package.


Please message me before ordering with your project brief, target chain, current code (if any), and expected deliverables. Large DeFi, DEX, and full-stack projects require custom pricing after scope review.
