I’m putting together a new Web3 product and want an experienced developer to take the technical lead from architecture through deployment. The overall concept is clear, yet the exact chain, framework, and contract structure are still open for discussion—your expertise will help drive those choices.

Scope
• Translate the product idea into a technical roadmap and milestone plan
• Design and build production-ready smart contracts (Solidity or comparable language)
• Connect the contracts to a lightweight dApp front-end and back-end API
• Set up reliable test, audit, and deployment pipelines so everything can launch to mainnet without surprises

Acceptance Criteria
• All contracts compile, pass unit and integration tests, and achieve ≥90 % coverage
• Code is verified on the target chain’s explorer and documented inline
• A short handover guide explains how to deploy, upgrade, and monitor the system

If you have a track record releasing secure smart contracts and dApps—and can start soon—let’s talk.
