I will build your android app with secure payments, pos, or offline first sync
About this gig
I've spent 10+ years building production Android apps for banks, fintechs, and POS payment systems used across multiple African countries including mobile banking apps, QR-code payment terminals, and offline-first apps for field agents working with no signal. If your app needs to handle money, sync data offline, or talk to hardware (printers, NFC, barcode/QR scanners), I've already solved that problem in production not just in a tutorial.
For simpler apps, I also build clean, modern Jetpack Compose / Kotlin Multiplatform (KMP) UIs end to end, from a single screen to a full MVP.
What I offer:
- Clean, maintainable, scalable code
- Modern Jetpack Compose UI / Kotlin Multiplatform (KMP)
- Offline-first architecture & data sync
- Payment, POS & hardware integrations (NFC, printers, scanners)
- REST API & database integration
- Play Store-ready apps
Whether it's a simple screen or a full product, I'll scope it clearly before we start.
Very large or complex apps (marketplaces, e-commerce, 20+ screens) need a custom quote message me first if that's you.

FAQ
What do you need from me to get started?
A clear idea of your app’s purpose, target audience, feature list, and any designs or references you may have. If you don’t have a design yet, I can help guide you through that too.
Can you connect the app to my existing backend or API?
Yes! I can integrate RESTful APIs, handle authentication, and work with your existing backend system — whether it’s in FastAPI, Laravel, or another stack.
Will you publish the app to the Google Play Store?
Yes, Play Store publishing is included in the Premium package. I’ll also guide you through setting up your developer account if needed.
Can you build for both Android and iOS?
Yes. If you want a cross-platform solution, I can use Kotlin Multiplatform or React Native depending on your project. Please message me to discuss scope.
Can I request changes after delivery?
Yes, revisions are included based on the package you choose. Additional changes beyond the included revisions can be quoted separately.
Do you offer ongoing maintenance or updates?
Absolutely. I offer continued support, bug fixes, and feature updates at an agreed hourly or fixed rate. We can discuss this after the initial delivery.
Do you provide app design (UI/UX) as part of the development?
While I don’t design the UI myself, I collaborate with talented designers who can create high-quality, user-friendly designs tailored to your app. Design services are quoted separately, and I’ll be happy to connect you or coordinate directly to ensure a smooth workflow.
Can you build a large, complex app like Uber or Facebook?
Yes, but those require a custom offer. The packages listed cover MVP apps up to 8–10 screens. Please message me before ordering for big projects.
