I'm a software engineer with 9+ years in mobile development, including 7+ years specializing in Flutter. I build production-ready applications, design maintainable architectures, integrate complex APIs and third-party SDKs, and work across mobile software and hardware-connected systems — from AI-powered healthcare kiosks to embedded multi-display Android platforms.
Production applications and the engineering behind them
A selection of the production mobile applications I've built or contributed to across healthcare, e-commerce, embedded systems, and more. Three projects below include a deeper engineering case study; the rest are summarized with their real screenshots, tech stack, and store links. Many additional projects can't be shown publicly due to client NDAs — see the note below.

iDoc Health
Case StudyLeading the Flutter engineering of an AI-powered telemedicine platform that connects patients and doctors through smart health kiosks, including real-time biomedical device integration.
Project Overview
iDoc is an AI-powered telemedicine platform that pairs AI-driven symptom checking with personalized health plans, connecting patients and doctors through smart health kiosks equipped with biomedical measurement devices.
My Role
Senior Software Engineer (Flutter) at iDoc, Apr 2024 – Jul 2026. I led engineering for the Android and iOS applications — owning software architecture, release management, and code review practices — and integrated biomedical devices directly into the app using serial communication protocols.
The Challenge
Kiosk hardware changes the shape of the problem: the app isn't just talking to a REST API, it has to parse live data streams from connected biomedical devices over serial/hardware interfaces and reflect them into a clinical workflow in real time — while still shipping and maintaining a normal Android/iOS release process across AI, backend, hardware, and product teams that don't normally share a codebase.
Technical Approach
Flutter with Clean Architecture and REST APIs for backend health services, plus a dedicated serial-communication layer that parses biomedical device data into the app's domain model, deployed on embedded Android kiosk hardware.
Key Engineering Decisions
Keeping the hardware/serial-communication layer behind a clean architectural boundary so device-integration work doesn't leak into UI or business logic, and owning code review and release practices to keep delivery consistent across a multidisciplinary team.
Outcome
iDoc Health is live today on the App Store, in active use connecting patients and doctors via smart kiosks. Its Google Play listing is currently unavailable.

Case Study
Open Source
Published an open-source Flutter plugin that runs independent Flutter engines across up to

flutter_multi_display
Case Study Open SourcePublished an open-source Flutter plugin that runs independent Flutter engines across up to three physical displays on a single embedded Android board, with real-time shared state between them.
Project Overview
flutter_multi_display is an open-source (MIT-licensed) Flutter plugin published
on pub.dev for building multi-display Android applications — useful for POS systems, digital
signage, kiosks, and restaurant/retail setups that need more than one screen driven from a
single device.
My Role
I designed, built, and published the package, and maintain it as open source under the MIT license.
The Challenge
Flutter's standard model assumes one engine renders to one display. Multi-display embedded hardware (e.g. RK3588-based Android boards) needs each physical display — up to three, one primary and two secondary — running its own independent Flutter engine, while keeping state synchronized across them in real time, which Flutter doesn't support out of the box.
Technical Approach
The plugin runs a separate Flutter engine per display, detects displays automatically or by
port (VGA/HDMI), and exposes a type-safe SharedState class — built on Flutter's
ChangeNotifier pattern — with state caching, so apps on different displays stay
in sync (e.g. a cashier display and a customer-facing display). The Android
MainActivity lifecycle is overridden to pause/resume secondary engines correctly
with the host app.
Key Engineering Decisions
Published as a standalone, MIT-licensed package rather than logic embedded in one closed product, so the multi-display/shared-state approach is reusable across different embedded projects. Scoped to Android only, matching the embedded hardware it targets.
Outcome
Publicly available on pub.dev (currently v0.0.3), documented with a full setup guide, API reference, and troubleshooting notes.
Architecture
One Flutter engine runs per physical display — a primary plus up to two secondary displays, sorted automatically or by port — with a shared, type-safe state layer keeping all of them in sync.
API Example
A condensed excerpt from the package's own public documentation — setting up the displays and keeping a value in sync across all of them.
// Setup — runs before runApp()
await FlutterMultiDisplay().setupMultiDisplay(
['screen1Main', 'screen2Main'],
portBased: true, // sort by VGA / HDMI
);
// Each secondary display gets its own entrypoint
@pragma('vm:entry-point')
Future<void> screen1Main() async {
WidgetsFlutterBinding.ensureInitialized();
runApp(const AdsApp());
}
// State stays in sync across all displays
class UserState extends SharedState<UserData> {
@override
UserData fromJson(Map<String, dynamic> json) => UserData.fromJson(json);
}

including its e-commerce app.

Shopini
Case StudySenior Software Engineer at Shopini (2021–2022) — built Flutter/GetX features, REST API integrations, and HyperPay payment integration across the company's mobile applications, including its e-commerce app.
Overview
Shopini is a Basra, Iraq-based company offering e-commerce with Iraq-wide delivery; its public Google Play listing reports over 1 million downloads. I worked here as a Senior Software Engineer, building features across the company's mobile applications rather than a single app.
Engineering Responsibilities
Senior Software Engineer, Nov 2021 – Nov 2022 (remote, Basra, Iraq-based company). My work included REST API integration, implementing HyperPay payment integration, diagnosing and fixing application performance issues, resolving production bugs, and release responsibilities — across multiple mobile applications built by the company.
Technical Stack
Flutter, GetX for state management, REST APIs for backend/catalog/order integration, and HyperPay for payment processing.
Product Outcome & Context
The company's Shopini e-commerce app has a public Google Play listing reporting over 1 million downloads. This is product-level context about the company's platform, not an individual result — my contributions were part of a broader engineering effort across several of the company's applications, not the sole basis for that figure.

How I work
I'm a software engineer who likes problems that sit below the UI layer — API and SDK integrations, hardware communication, state that has to stay correct across screens or devices, and the architectural decisions that keep a codebase maintainable as a product grows.
Most of my 9+ years in mobile have been in Flutter, but the common thread across healthcare kiosks, payment integrations, and embedded multi-display hardware is the same: build something production-grade, make it reliable, and make it something the next engineer can actually maintain. I work closely with backend, AI, hardware, and product teams, and I've led engineering teams across concurrent product lines.
