FAQ
Do you build just mobile, or also web and desktop?
I build across all three. Flutter covers iOS, Android, web & desktop from one codebase. For web I also use React, Next.js, and Node.js or Laravel backends. Message me and we'll find the right approach.
Which AI APIs do you support?
OpenAI (GPT-4o, DALL-E 3), Google Gemini, and Anthropic Claude. I can also integrate custom REST APIs or open-source models like LLaMA. We will discuss the best fit before starting.
What does "full stack" mean in your gig?
It means I build both the frontend (the app the user sees) and the backend (the API server, database, and AI logic). You get a complete, deployable product — not just a frontend that calls someone else's API with no backend of your own.
Do you provide the full source code?
Yes, always. You receive 100% of the source code — frontend, backend, and any configuration files — along with a setup guide. No lock-in, no hidden files.
Can you help deploy or publish the finished app?
Yes. For mobile I assist with App Store and Play Store submission. For web I can help with deployment to Vercel, Firebase Hosting, or VPS. For desktop I can package installers for Windows (MSIX/EXE) and macOS (DMG). Full deployment help is included in the Premium package.
I have a custom idea that is not listed. Can you still build it?
Absolutely. Send me a message describing your idea and I will tell you exactly what is possible and give you a custom quote if it falls outside the standard packages.
