FAQ
Questions founders ask before hiring an MVP developer.
Can a real MVP be built in 3 weeks?
Yes, if the scope is disciplined. The goal is not to build every future feature. It is to ship the smallest useful product that lets real users sign up, pay, and use the core workflow.
Do I need a technical co-founder first?
No. You need a clear problem, a defined first audience, and someone technical who can make sensible product decisions with you. You keep the equity and own the code.
What happens if my idea is too big for the fixed price?
I will tell you before we start. The first call is partly a fit check: what can ship now, what should wait, and whether this offer is the right route.
Will I be able to hand the app to another developer later?
Yes. You get the repository and setup in your accounts, using common frameworks and services another developer can understand.
Ready to build?
Bring the idea. I will help cut it into a shippable MVP.
