Joseph M
About this gig
Your mobile app idea deserves more than attractive screens, unfinished features, and a development process that leaves you guessing.
Whether you're launching your first MVP or improving an existing app, I help turn your vision into a polished, functional Flutter application built around your business goals and your users.
I turn designs and requirements into polished Flutter experiences for Android and iOS.
WHERE I ADD VALUE
- Figma prototypes that need to become functional apps
- Confusing layouts, inconsistent UI, and broken navigation
- Firebase login, data features, and REST API integrations
- Unfinished MVPs and bugs holding up progress
HOW I WORK
We align on your users, priorities, and project scope. I build the agreed screens and features, share progress updates, test key flows, and prepare a clear handover.
WHAT YOU RECEIVE
Flutter/Dart source code, agreed features, applicable test builds, and setup notes, based on your package. For React Native or advanced features, request a custom quote.
Send your Figma file, project brief, or existing app details. Let's define the right build plan before you order.

FAQ
Can you turn my app idea into a working mobile application?
Absolutely. Whether you have a detailed concept, rough sketches, or a Figma design, I can help you define the development scope and build a functional Flutter application that supports your business goals.
Can you convert my Figma design into a functional Flutter app?
Yes. I can transform your Figma UI/UX designs into responsive Flutter screens with navigation and agreed functionality, while maintaining visual consistency with your original design.
Can you develop an app for both Android and iOS?
Yes. Flutter supports cross-platform development using one codebase. I'll confirm your target platforms and required builds before development so the deliverables match your selected package.
What if I already have an app that needs improvements?
You don't necessarily need to start from scratch. Share your existing Flutter project and explain the issues you're experiencing. I can review the code, identify possible solutions, and provide a quote for the required fixes.
Can you integrate Firebase, APIs, and user authentication?
Yes. I can implement Firebase authentication, connect supported REST APIs, and develop agreed data features. The integrations included depend on your package, while more complex requirements can be quoted separately.
How will I know my project is progressing correctly?
I believe clear communication is essential to successful development. We'll agree on the project scope, important milestones, and expected deliverables before work begins, with progress updates throughout development.
Will I receive the complete source code?
Yes. You'll receive the Flutter/Dart source code and the deliverables included in your package, along with relevant setup notes to make future maintenance and development easier.
Can you publish my app on Google Play or the Apple App Store?
I can discuss store-readiness requirements and deployment support. App Store and Google Play submission are not automatically included in the listed packages and require a separate agreement.
What happens if I need changes during development?
Revisions are handled according to your selected package and agreed project scope. My priority is making sure the approved features work as expected. New features or major design changes may require additional work.
What information should I provide before placing an order?
Share your app idea, target users, preferred platform, estimated number of screens, Figma file or references, and required features. I'll review your requirements and help you identify the most suitable package or custom offer.
