FAQ
Do you provide smart contract development?
I focus on backend system and API development. I can integrate your existing smart contracts with custom Java backends, but I do not write smart contracts from scratch.
What do you need from me to start
I will need your detailed requirements, API specifications, and access to your smart contract ABI (if applicable).
Can you help with smart contracts?
My core expertise is Java backend development, but I can help with simple contract integration, testing, or providing guidance. For custom contract development, I recommend working with a dedicated Solidity developer, and I can help integrate their work with your backend system.
