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.

    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.
