EVM/Solidity engineer with Java/Spring and Node/TypeScript backend experience.

I design, implement, and test smart contracts, then integrate them into Web3 apps (React + APIs).

Highlights:
• Built a prediction-market stack (contracts, matching/backend services, Foundry tests)
• Recent Sepolia delivery (ERC20 + Express mint/burn/balance):
 https://sepolia.etherscan.io/address/0x8fC6913efC7b3D3679F756E2511B8e50B2219348
• PrediX-related Sepolia contract:
 https://sepolia.etherscan.io/address/0xf14aa9339812a94f058da0ed972d68479651a11d
• GitHub: https://github.com/predix-sea

Looking for fixed-price or milestone-based gigs: Solidity contracts, Foundry tests, Node/TS integration, Web3 backend work.
Available to start this week. Prefer escrow / milestone payment.
