FAQ
What do you need from me to get started?
To ensure we build exactly what you envision, I need a clear list of features (or user stories), any API keys we might need (like OpenAI or Stripe), and a UI design (Figma, Adobe XD) if you have one. If you don't have a formal document, we will have a video call discussing your project
What if I don't have a UI/UX design ready?
No problem! If you don't have a custom Figma design, I will use my own design to build a clean, responsive, and professional interface based on your brand colors. We can have many revisions during development to make sure it is to your liking.
Will I own the source code after completion?
Absolutely. Once the order is marked as complete, you retain 100% ownership of the application and its complete source code. I can push the code directly to your GitHub repository or send it as a zipped file.
