Hello, I am a mobile app developer building cross-platform mobile apps for iOS and Android with Flutter, backed by Firebase and Supabase for scalable, real-time infrastructure. I specialise in AI-powered mobile apps, integrating and fine-tuning AI models to add intelligent features like personalisation, automation, and smart recommendations.
From clean UI to backend logic, I handle the full development cycle with a focus on performance, clear communication, and fast turnaround. If you need a reliable app built right, let's talk.

FAQ
How do I know the AI features will actually work for my app idea?
Before we start, I'll walk through your specific use case and confirm the right approach, whether that's a simple API integration, a custom chatbot, or a fine-tuned model. You'll know exactly what's technically possible and what the AI will actually do before any code is written, so there are no sur
What if I don't have a design ready, can you still build my app?
Yes. I can work from wireframes, a rough sketch, a reference app, or even just a written description of what you want. If you have a Figma design, I'll build directly from it. If you don't, I'll design a clean, functional UI as part of the build so you're not stuck waiting on a designer first.
Will I own the app and source code once it's done?
Absolutely, full ownership transfers to you on delivery. You get the complete source code, and I'll help you set up your own Firebase project, API keys, and app store accounts so everything from day one belongs to you, not tied to my systems.
