About this gig
Hi! I'm Oscar, a Flutter developer with 30+ apps delivered to clients worldwide.
I build AI-powered mobile apps for iOS and Android from one clean Flutter codebase GPT, Gemini or Claude integrated into a real product, not a demo. Scalable Firebase backend and professional UI/UX designed in-house.
What I integrate:
- AI chatbots & assistants (GPT / Gemini / Claude)
- Smart search & recommendations
- Image & document analysis
- Voice input and transcription
- Custom prompt flows for your business logic
I build apps for:
- E-commerce & shopping
- Food delivery & restaurants
- Booking & services
- Fitness & health
- Social & community apps
How I work:
No upfront payment. You approve a testable build at every phase before moving forward. You get the full source code and 30 days of support after delivery.
I work in English and Spanish, and I reply within 1 hour.
Message me before ordering so we can scope your app properly.

My Portfolio
FAQ
What do you need to get started?
Just your app idea and any references or features in mind. We define the scope together before you order that's why I ask you to message me first.
Which AI models do you work with?
GPT (OpenAI), Gemini (Google) and Claude (Anthropic). I integrate their APIs directly into your Flutter app. If you already have an API key I'll use yours; if not, I'll guide you through setting one up.
Do you design the app too?
Yes. Design and development come together a professional UI/UX so your app looks as good as it works.
Do you charge upfront?
No. I work in phases and deliver a testable TestFlight build at the end of each one. Fiverr holds the payment and releases it only after you approve.
Will I get the source code?
Yes, full source code is included in the Standard and Premium packages.
Do you train custom AI models?
No, I integrate existing models through their APIs, which is what 95% of apps actually need and is far cheaper and faster. If your project truly requires a custom trained model, I'll tell you upfront instead of taking the order.
What if I need changes or a bigger app?
Each package includes revisions and I offer ongoing support. For larger, multi-phase apps I send a custom milestone-based offer.
Will the AI features work on both iOS and Android?
Yes. One Flutter codebase means every AI feature works identically on both platforms, with no extra cost or delay.
