FAQ
How long will it take to complete my project?
Timeline depends on complexity. Small tasks take 2–3 days, medium projects up to a week, and large Web3 systems 2–3 weeks. I always provide a timeline before starting.
Can you work with my existing code?
Yes. I can review, refactor, or extend your existing codebase. If the code is outdated or poorly written, I’ll also advise you on what should be rebuilt.
Do you provide after-delivery support?
Absolutely. Every order comes with free support for 10 days after delivery. Larger projects include longer support periods.
Will you deploy the project for me?
Yes. Deployment is included for all packages. I’ll handle servers, domains, SSL, and Web3 contract deployments, so everything is production-ready.
What blockchains do you specialize in?
I mainly work with Ethereum (EVM) and Solana, but I can also support Polygon, BSC, Arbitrum, and Avalanche. If you’re unsure which chain fits your idea, I’ll guide you.
What if I don’t have a design?
No problem, tell me the style you want. I can create clean, modern UI/UX layouts from scratch.
Can you build my project from zero?
Yes. I can handle everything from architecture planning to launch. You only need to explain the idea; I handle the rest.
