Senior mobile engineer Available worldwide

Mobile apps with the finish of a flagship.

I am Abdullah Ali. I design and ship Flutter, Kotlin, React Native, and Java applications for teams who care how software feels in the hand — not just whether it compiles.

Selected products

A short list of shipped apps — fintech, social, commerce, and tools people actually keep installed.

How a project runs

No black box. You see builds every week, and we decide the next cut together.

01

Scope

A working session to pin down users, constraints, and the stack. We leave with a feature cut, a timeline, and a list of what we are deliberately not building.

02

Build

Interface and architecture move together. You get weekly builds, not a big reveal at the end. We tighten copy, motion, and edge cases while the product is still cheap to change.

03

Launch

Store submission, QA, crash reporting, and the last 10% that makes an app feel finished. Support continues after the listing goes live.

Abdullah Ali — Senior Mobile Developer

Built for production, not for a demo reel

I am a senior mobile engineer working across Flutter, React Native, Kotlin, and Java. The work is the same in every stack: clean structure, honest performance, and an interface that does not fight the platform.

Most of the apps I have shipped sit in fintech, social, commerce, and productivity — products that have to stay up, stay fast, and stay understandable after the first launch week.

  • — Interface work that respects platform conventions
  • — Motion that supports the task, not the other way around
  • — Architecture that still makes sense a year later
  • — Auth, APIs, payments, maps, and offline storage
  • — Store listing, review, and post-launch support

The stack I reach for

Cross-platform when the product wants one codebase. Native Android when the hardware or the OS is the point.

01

Flutter

One codebase, two stores, and enough control to make the UI feel considered. Strong choice when design and speed of iteration both matter.

  • Shared Android and iOS delivery
  • Custom motion and complex layouts
  • Consistent 60fps UI when done properly
02

React Native

Native controls with a JavaScript team already in place. Useful when web and mobile need to share people, patterns, and release cadence.

  • Over-the-air updates
  • Mature library ecosystem
  • Native module bridges when needed
03

Kotlin / Java

Direct access to the Android SDK for products that need hardware, background work, or a smaller, tighter binary.

  • Deep platform APIs
  • Native system components
  • Lean, focused APK builds

Currently on the bench

Work in planning, active build, or late testing — with a public date when one exists.

Straight answers

What technologies do you specialize in? +
Flutter (Dart), React Native (JavaScript/TypeScript), Kotlin, and Java for Android. I also work with Firebase, REST APIs, GraphQL, and the usual backend pieces a mobile product needs.
How long does a typical project take? +
A focused MVP is usually 3–5 weeks. A fuller cross-platform product is closer to 6–10 weeks. Larger work is scoped on its own. You get a dated plan before anything is billed.
Do you handle app store publishing? +
Yes. Google Play submission is part of the work. iOS App Store listing — metadata, screenshots, and review handling — is included on fuller engagements.
What is your payment structure? +
Fixed-price work is typically 50% to start and 50% on delivery. Larger projects can be invoiced by milestone. Bank transfer, PayPal, and USDT are all fine.
Will I own the source code? +
Yes. After final payment you own the source, design files, and project assets. No licence trap, no lock-in.
Can you work with an existing codebase? +
Yes. I regularly take over Flutter, React Native, and native Android codebases — to add features, clean structure, or fix performance.
