Expert judgment + AI speed — that's how I lead. I fix broken Flutter & Android apps and ship startup MVPs — fast, with AI, but with the judgment of 1,200+ real production hours. I'm an engineer who uses AI to move faster, not a prompt-jockey who ships code he can't debug. Top Rated · 100% Job Success · 1,200+ hours · apps live on both App Store and Google Play. What I do best: • App Rescue & Stabilization — inherit a messy or broken codebase, kill crashes, fix performance, store rejections, and SDK/version issues, and get you shipping again. • Flutter / Android MVPs — turn a rough idea into a focused, store-ready app: auth, payments (in-app purchases & subscriptions), Firebase, REST APIs, release. • AI-accelerated delivery — I build with AI to cut your time and cost, then review every line so it survives real users — not a demo that breaks on day one. Why clients keep me (15 five-star reviews, repeat clients): reliable, clean code, clear communication, and I understand the problem before I touch the keyboard. I also build the backend and automation behind the app — Node.js, APIs, Firebase/AWS, and multi-agent AI workflows — so you can hire one person instead of three. Need an app fixed or an idea shipped? Message me with what's broken or what you're building, and I'll tell you honestly what it'll take.

"I can unreservedly recommend Hussein for the development and support of Android apps. Over the last 2 years, Hussein has delivered amazing work, providing everything we need for Android, Android Auto, and Android Automotive. I have been impressed with how quickly he has supported complex challenges including Mapbox integration, Android Automotive, cloud-based comms, SignalR, and MQTT. 100% recommended." - Client, UK Transport Authority I'm an Android engineer with 4+ years across product companies and freelance work. My specialty is apps that talk to hardware (BLE devices, car head units, sensors), but my day job is production Android at scale, so you get both. 🛠️ WHAT I'VE ACTUALLY SHIPPED 🛒 E-commerce (current role at a software studio): - Cut checkout loading from 12-15s to 2-4s (83% faster) by reworking GraphQL queries, caching, and business logic - Led full migration from XML to Jetpack Compose with MVI, reviewing code and supervising the team - Integrated Payfort and Paymob payment gateways, built Loyalty and Gift Card systems with animated Compose Canvas UI 🚗 Android Automotive & Auto (2 years, UK Transport Authority, UK): - In-vehicle warning app running on a Polestar head unit, tested at Warwick University, covered in industry press (LCRIG) - Road safety and city safety apps: Mapbox, Google Maps, real-time location, MQTT, SignalR - Trained a TensorFlow Lite model with CameraX detecting vehicles for driver safety scoring 📡 BLE & Embedded (my own product, end to end): - Designed a BLE wearable from zero: custom 4-layer PCB (nRF52840, PMIC, capacitive touch), Zephyr firmware with OTA firmware updates over BLE, a Compose Multiplatform (KMP) companion app, and a Ktor backend behind it. I debug every layer: sensor, firmware, app, and server. 🔒 Security & hardened apps: - Built a 7-layer protection system for a client app: Talsec RASP, custom C++ native module for Frida detection, hardware-backed AES-256 with Android Keystore, SQLCipher, ProGuard/R8, string encryption, certificate pinning - Secure chat app: message and file encryption, voice recording, CameraX capture, root detection, USB debugging prevention. Cut its CPU usage by 30% and memory by 80% through profiling - System-level call/SMS handling with CallScreeningService inside Android's 5-second response window ☁️ Backend & self-hosted: - Ktor REST APIs with MySQL, Exposed, and Docker, sharing a Kotlin module between server and app for type-safe contracts - Device telemetry (GPS with 5-tier fallback, signal strength, battery), OTA APK updates, FCM remote commands and Remote Config - I run my own self-hosted infrastructure (Docker, Linux, reverse proxies, monitoring), so I'm comfortable deploying and maintaining what I build 📱 MY OWN PRODUCT - GPA Manager on Google Play: 16K+ downloads across 80+ universities, live Firebase backend Plus 20 completed Upwork contracts: in-app purchases and subscriptions, survivable background services, GPS tracking, offline data capture, SDK migrations. 🤝 HOW I WORK GitHub access from day one so the code is yours at every step.

The first consultation is free: tell me about your project and I'll give you my honest take on the approach, effort, and risks before you spend anything.

Software engineer working on android apps and websites, seeking for more information and experience everyday.

I build production Android apps that ship and stay shipped. Arcadia, my AI-powered game tracker, took 1st place in a national Egyptian tech initiative out of 120,000+ participants and is live on the Play Store. FlexPing, built for a UK client serving Amazon Flex drivers, is live on Google Play and maintained by me in production today. My core stack is Kotlin, Jetpack Compose, MVVM, Coroutines, REST APIs, and Firebase. I'm also building a multi-tenant restaurant SaaS in Kotlin Multiplatform, with iOS and Android sharing one codebase. Shipping the UI is the easy part. I own the systems behind it: clean architecture, backend and Firebase integration, and the performance work most projects skip, baseline profiles, memory profiling, app-size reduction. That's the difference between an app that demos well and one that survives real users. I work best on long-term and contract-to-hire roles where I own a meaningful part of the codebase, not just close tickets. If you need an Android developer who ships and owns the outcome, message me.
