FAQ
I have an idea but I am not sure if it is buildable - can you still help?
Yes, this is exactly where to start. Send me a message describing what you want to automate or build and I will tell you what is realistic, what tools fit, and what a lean first version looks like. No commitment needed to have that conversation.
How long does a build actually take, and what happens along the way?
Starter MVPs ship in 5 days, full SaaS MVPs in 10, production builds in 30. You get a scope agreed before I start, a working preview partway through so you are never waiting blind, and the handover package at the end. If something will take longer than quoted, you hear it from me before the deadline
Will I own the code and be able to hand it to my own developer later?
You get full ownership of all source code. I also deliver a README and handoff notes so any developer can pick it up. Support questions for 14 days after delivery are included.
How is this different from using Lovable, Bolt, or Replit to vibe-code my app?
Those tools hit a ceiling fast. I write production-grade code with real auth, error handling, and scalable architecture. 400+ automations and apps built - this holds up under real usage.
What if the project turns out bigger than the package I ordered?
We agree on scope before you order, so surprises are rare. If real requirements grow, I flag it early and we adjust together - no hidden charges dropped on you at the end.
