I am building out the core of a new product on the Solana blockchain and need a seasoned engineer to write, test, and deploy custom smart contracts. Your job is to translate a set of functional requirements into secure, efficient on-chain programs, then walk me through deployment and version control so I can maintain the codebase moving forward. The role is 100 % Solana focused, so I expect fluency with Rust, Anchor, the Solana CLI, and standard auditing tools. If you also enjoy crafting full dApps or connecting on-chain logic to existing back-end services, that will be useful down the line, but for this phase the deliverable is solely the smart contract layer. Deliverables – Well-documented Rust/Anchor smart contracts that satisfy the functional spec – Local and test-net deployment scripts – A short hand-off session (recorded) covering build, test, and upgrade steps I am ready to start as soon as we agree on milestones and timelines. Let me know your experience with previous Solana main-net contracts, any open-source repos you can share, and your preferred approach to security reviews.
