About this gig
Mobile AI is hard. Latency, token costs, and state management kill most projects.
As a Senior Full-Stack Engineer, I don't just wrap the ChatGPT API in a Flutter webview. I engineer robust, native-performance AI SaaS Mobile Applications.
I specialize in building complex business toolslike my recent AI Meeting Assistant (see portfolio)that handle real-time data, long-context memory, and secure user authentication.
My Architecture Approach:
- The Brain: OpenAI (GPT-4o) or Claude 3 for reasoning.
- The Memory (RAG): Pinecone/Weaviate vector database to let the AI "chat with your documents" (PDFs, Notion, etc.).
- The Framework: Flutter for a single, high-performance codebase on iOS & Android.
- The Backend: Firebase or Supabase for real-time data sync and auth.
- Monetization: RevenueCat integration for seamless In-App Purchases and subscriptions.
Why this isn't a $95 gig: Building a production-ready mobile app requires handling edge cases, app store compliance, and scalable backend infrastructure. I deliver code that is ready for investors and users, not just a hackathon demo.
Ideal for: B2B SaaS founders, FinTech startups, and specialized professional tools.

FAQ
Do I need my own OpenAI API key?
Yes, you need your own OpenAI API account. I will build the app to use your API key, giving you full control over your usage limits and billing directly with OpenAI.
Will the app work on both iOS and Android?
Yes! I use Flutter for development, which allows me to deliver high-quality, native-performance apps for both iOS (iPhone) and Android platforms from a single codebase.
Can you train the AI on my specific data?
Yes. I can use techniques like "Prompt Engineering" or "RAG" (feeding your data to the AI context) to make the app answer based on your specific documents or website content. Message me to discuss this!
Can I charge users to use the app?
Absolutely. I can integrate In-App Purchases (IAP) or subscription models (like RevenueCat) so you can monetize premium AI features or offer monthly subscriptions to your users.
Do I get the full source code?
Yes, upon final delivery, you will receive the complete source code. You will have full ownership of the project and can modify it in the future if needed.
Do you provide the UI/UX design?
Yes, I create clean, modern interfaces designed specifically for AI interactions. If you already have a design (Figma/XD), I can also build strictly according to your files.

I needed to build an AI chatbox for my real estate live web next js web app that will fetch property data very fast without the agents having to sort through 100s of property listings. They created an AI chatbox for us that does all this and I'm quite excited to have worked with them. We'll be working with them for more projects in the future.
