I will build an ai mobile app with flutter and a python backend
Nisar Khan
About this gig
Need a mobile app that ships on Android, iOS and the web - without paying for three separate builds?
MS Data Science, IBM Data Science Professional. I build cross-platform apps with Flutter and Dart, backed by Node.js/TypeScript or Python APIs - and because AI is my core field, your app can include an AI assistant, smart search, recommendations or document scanning.
Recent build: a restaurant app for a private client - ratings and reservations with Google Maps and Safepay payments on one side, a restaurant management view on the other - rolling out on Google Play, the App Store and the web via AWS.
What you get:
- One Flutter codebase: Android + iOS + web
- Clean architecture, state management and source code you own
- Backend: Node.js/TypeScript or Python API, PostgreSQL, Firebase or AWS
- Google Maps and Places location features - Safepay/Stripe payments
- Store-upload guidance + a recorded walkthrough
Stack: Flutter, Dart, Node.js, TypeScript, Python, PostgreSQL, Redis, Google Maps/Places, AWS.
Place your order - describe your app idea in the requirements form, or message me a one-line pitch and I will scope it fast.

I build production AI agents and RAG chatbots with Claude Code and Python, AI document-extraction pipelines (OCR), and cross-platform mobile apps with Flutter - including a real restaurant reservations app rolling out on Google Play, the App Store and web via AWS. Verified results: 92.85% ROC AUC churn model, Prophet R2 = 0.80 on 160K+ listings, SVM 86% on 4M+ reviews, across 20 portfolio projects. My promise: honest scoping before you order, plain-English answers, fast replies, and code you own outright.

FAQ
Why one codebase for three platforms?
Flutter compiles the same Dart code to Android, iOS and web — one build, one bill, consistent design, and every fix lands everywhere at once.
Can you really add AI to the app, or is that a buzzword?
It's my core field — my AI work includes shipped RAG chatbots and OCR pipelines with named results. In-app assistants, smart search, recommendations and document scanning are all buildable, scoped honestly in advance.
Have you built and shipped a real app?
Yes — a restaurant ratings-and-reservations app for a private client (Flutter + Next.js on AWS), rolling out on Google Play, the App Store and the web. I can walk you through the architecture on a call.
Do I get the source code and who owns it?
You do — full Flutter/Dart source, backend code and docs on delivery. I keep no copies; NDA available on request.
What about app store approval?
Standard includes upload guidance; the submission extra covers doing it with you on your own developer accounts (Google/Apple fees are yours). I build to store guidelines from day one to avoid rejections.
What backend do you use, and can the app take payments?
Whatever fits: Firebase for speed, or a custom Node.js/TypeScript or Python API with PostgreSQL on AWS for scale. Maps and location search use the official Google Maps and Places APIs on your own keys — and yes, I integrate payment gateways (Safepay, Stripe) on your own merchant account.
How do revisions work on an app build?
Per package (1/3/5). A revision tunes what was scoped — screens, flows, styling, AI behavior. New screens/features are added transparently as extras, agreed before any work starts.
You have no reviews yet — why should I trust a big build to you?
Fair question. My credentials are publicly verifiable (MS Data Science; IBM certified), the restaurant app is a real named build, and the Basic tier is a small, low-risk pilot. Fiverr's resolution centre protects your order throughout.
How fast do you respond, and can we do milestones?
I reply within a few hours (UK/EU morning + US-East afternoon overlap, async via Fiverr). For Premium builds, Fiverr Milestones can split the project into approved stages.
Can the app talk to my documents or data?
Yes — that's where my other gigs plug in: a RAG chatbot over your content, or OCR document scanning inside the app. Tell me the use case and I'll propose the simplest architecture.
