Web3 & AI developer. Solidity, Java and TypeScript. Runnable examples for payments, wallet permissions and content licensing.

I’m HaoJie Luo, an independent developer working on Web3 and AI applications. I write about payment workflows, wallet permissions and content licensing, with runnable examples and tests. My client handovers typically include testnet delivery and deployment scripts. Clients or their operations teams handle production deployment. The public examples use separate business logic from client projects. Projects and engineering notes: https://fone.cc/?utm\_source=hashnode&utm\_medium=referral&utm\_campaign=profile
