Veelgestelde vragen
What kind of Web3 and dApp solutions can you build?
I can help with Web3 backend development, dApp architecture, wallet integrations, blockchain event processing, crypto payment flows, smart contract development and audit, APIs, and custom business logic for blockchain-based products.
Do you develop full dApps or backend only?
My strongest area is backend and integrations, but I can also help with overall dApp architecture and backend-to-frontend interaction. If needed, I can work as part of a larger product team.
Which blockchains can you work with?
I can work with EVM-based blockchains (Ethereum, Polygon, Solana) and Tron.
Can you work on an existing project?
Yes. I can join an existing codebase, review architecture, improve integrations, optimize backend logic, and help extend a running Web3 or dApp product.
What do you need from me before starting?
A short description of the product, current status of the project, the blockchain or platform involved, your goals, and any technical details or repository access if available.
