About this gig
Your buyers expect AI inside your app - ChatGPT-style chat, smart assistants, voice replies, generated content. Most Flutter developers can't ship it. I do, and I deploy to both stores.
What you get:
- Cross-platform Flutter app for iOS and Android from a single codebase
- ChatGPT, OpenAI, Gemini, or Claude integration - streamed responses, chat history, prompt engineering done right
- Firebase backend: auth, Firestore database, Cloud Functions, push notifications
- Stripe or in-app subscription billing for AI usage (token tracking, paywall, free-tier limits)
- Clean architecture so your codebase scales past MVP - not a throwaway prototype
- Play Store and App Store submission included
- Full source code, documented, yours to keep
How it works:
- You send your brief, Figma file (if you have one), and the AI features you want
- I reply within 1 hour with a scope, timeline, and architecture plan - before you order
- I build in milestones with screen-by-screen previews, not a black box
- You review, request revisions, and approve final delivery
- I help submit to Play Store and App Store
Send your project details, I reply within 1 hour with a fixed quote, a real timeline, and a clear architecture plan.

FAQ
1️⃣ Will my app work on both iOS and Android from a single codebase?
Yes. I build in Flutter, which compiles to native iOS and Android from one codebase. You get the same UX on both platforms, faster development time, and one codebase to maintain instead of two. I've shipped 150+ apps this way since 2020.
2️⃣ Which AI models can you integrate — ChatGPT, Gemini, Claude, or something custom?
All of them. I work with OpenAI (ChatGPT, GPT-4, GPT-4o), Google Gemini, Anthropic Claude, and custom LLMs via REST API. I'll recommend the right one based on your use case, latency requirements, and budget. Models can also be switchable inside your app so users pick their preferred one.
3️⃣ Can you connect the app to my existing Firebase, Supabase, or backend?
Yes. Firebase is my primary backend (Auth, Firestore, Cloud Functions, Storage, FCM) and I'm Google Cloud Certified, so I can also build on GCP directly. I work with Supabase, custom Node.js REST APIs, GraphQL, and any system with documented endpoints.
4️⃣ Will I get the full source code, and can I publish to Play Store and App Store myself?
Yes, every package includes full source code, documented, in your GitHub or a delivered zip. Premium includes my help with App Store and Play Store submission — you provide the developer accounts, I handle the technical submission and respond to review feedback.
5️⃣ have an existing Flutter app — can you add AI features to it instead of building from scratch?
Yes, this is one of my most common projects. I'll review your existing codebase, propose where AI fits cleanly without breaking your architecture, and integrate it in milestones. I never rewrite your app unless I find a real reason to — usually I drop AI features into your existing structure.
