Hi, I’m Hassan, an Android developer who builds fast, clean and user-friendly mobile apps. I work mainly in Kotlin and Java with the Android SDK, and I also build cross-platform apps in Flutter. My work follows MVVM and clean architecture, with Firebase, REST APIs, SQLite and Google Maps integration. Whether you need a new app from scratch, new features, or bug fixes in an existing app, I’ll deliver clean, well-structured code on time. Send me a message with your idea and let’s build something great together.
FAQ
Do you provide the full source code?
Yes. Every package includes the complete, clean source code, so you fully own your app.
Can you build the app from my design?
Yes. I can work from Figma, Adobe XD, screenshots, or even a hand-drawn sketch. If you don’t have a design, I can create a clean UI for you in the Standard and Premium packages.
Can you upload my app to the Google Play Store?
Yes, in the Premium package. I’ll prepare a Play Store-ready AAB and upload it using your own Google Play Console account.
Can you fix bugs or add features to my existing app?
Yes. Send me your project or source code, and I’ll review it and give you a clear quote. Small fixes fit in the Basic package.
Do you also make iOS apps?
Yes, using Flutter, which lets one app run on both Android and iOS. Message me before ordering to discuss the details.
What do you need from me to start?
Your app idea and main features, your design or reference apps you like, and any API or Firebase details. Please message me first so we can agree on scope and timeline.
