I will do crossplatform mobile app development
Jasim N.
About this gig
You have an app idea. You need it built clean, fast, and ready for real users not a prototype that falls apart the moment someone actually uses it.
I've shipped 60+ production apps over 7 years across fitness, e-commerce, on-demand, and SaaS apps with real users, real subscriptions, and real Firebase backends that don't send you a surprise $4,000 bill at the end of the month.
What you get with every project:
- Clean Flutter codebase for both iOS and Android
- Firebase integration: Auth, Firestore, Storage, Functions
- Push notifications, deep linking, and third-party API connections
- App Store and Play Store ready builds
- Bug-free delivery with post-launch support
I don't disappear after delivery. If something breaks, I fix it.

FAQ
Q: Do you build for both iOS and Android?
A: Yes, Flutter gives you a single codebase that runs natively on both platforms. You get one app, two stores, no compromise on performance.
Q: Will I own the source code?
A: Absolutely. Full source code, GitHub repository access, and complete ownership transfers to you upon final delivery. No strings attached.
Q: Do I need to already have a backend or Firebase setup?
A: Not at all. I set up the entire Firebase project from scratch — Auth, Firestore, Storage, and Functions — as part of the build.
Q: How long does a typical project take?
A: Basic apps take 1–2 weeks. Standard projects run 3–5 weeks. Complex premium builds are typically 6–10 weeks depending on scope agreed upfront.
Q: What if I need changes after delivery?
A: Minor revisions are included. For larger changes or ongoing work, I offer retainer arrangements so you always have someone who knows the codebase available.
Q: Do you handle App Store and Play Store submission?
A: Yes on Standard and Premium packages. I handle certificates, provisioning profiles, metadata, screenshots, and the full submission process.
Q: What do I need to provide to get started?
A: App design or rough wireframes, any existing brand assets, and a clear description of what the app should do. I'll handle the rest and guide you through any missing pieces.
Q: Can you work with my existing designer or designs?
A: Yes. If you have Figma files or any design mockups ready, I'll build pixel-perfect from those. If not, I can suggest a design partner or work from your brief.
