I build Flutter apps
that feel effortless
.
Software Engineer · Flutter Developer
I design and ship mobile apps with clean architecture, from enterprise systems to consumer products.
Two years of shipping real Flutter products.
I'm a Computer Science & AI graduate from Damietta University, and I've spent the last two years building Flutter apps end-to-end — from enterprise ERPs handling live financial transactions, to asset-tracking systems used daily in the field, to a personal productivity app live on the Amazon Appstore. I care about Clean Architecture, code that scales past the demo, and interfaces that get out of the user's way.
What I focus on
- Clean Architecture that scales past the demo
- State management done right — BLoC, Provider, Riverpod
- Offline-first thinking for real-world conditions
- Interfaces that get out of the user's way

Looking to join a team that ships thoughtful, reliable mobile products.
Work Experience
From an enterprise engineering team to freelance client delivery.
Contributed to production mobile features using Flutter and Clean Architecture within a professional engineering team — applying BLoC state management and collaborating on code reviews and technical planning.
Architected and deployed multiple production-ready apps focused on multi-role authorization and real-time synchronization — reducing crashes and improving load times through optimized API consumption and caching.
Selected for an intensive workshop on enterprise-level mobile architecture and UI performance optimization, building performant UI components to industrial clean-code standards.
Featured Projects
Eight products, eight very different problems — all shipped in Flutter.
Azzam
An ERP system with 8+ distinct user roles, complex permission logic, and real-time financial tracking — including a multi-payment gateway supporting USDT, bank transfer, and cash.
Estdama
Lead developer for an asset-tracking solution with high-speed QR-code scanning, auditing, and real-time monitoring dashboards built for offline-first field use.
Me App
Published on the Amazon Appstore — an offline-first app for advanced personal metric tracking, with custom goal algorithms synced across devices via Firebase.
Childcare Center App
A three-sided platform for daycare centers with dedicated Admin, Parent, and Teacher experiences. Admins approve or reject teacher and child registrations, review full profiles, and get notified before a child's enrollment period ends — with the option to extend or remove them. When a teacher is removed, the admin is automatically alerted to reassign her children.
Teachers send parents real-time updates on drop-off, meals, clothing changes, and pick-up, and both teachers and admins can chat directly with parents — with admins able to oversee every conversation.
Smart Wheelchair Assistant
The mobile layer of a smart wheelchair ecosystem — controllable via joystick, app, or autonomous navigation. Streams real-time health data from IoT sensors (heart rate, MPU), and powers an emergency alert system with manual and automatic triggers plus live location sharing.
Includes remote doctor monitoring, an AI-powered assistant and chatbot, a Category → Organization → Building → Floor → Place accessibility navigation hierarchy, and a community platform for peer support.
Quiz Me
A study app that lets students test themselves on their own terms — add a subject, write your own questions, run the quiz, and get an instant score at the end.
Yom El-Rashaka
A fitness and nutrition app for planning meals and workouts, taking on challenges with friends, and following up with a specialist. Includes an in-app store for browsing subscription packages, with payment handled directly in the app.
Al-Modeef
A booking marketplace for finding and hiring cleaning staff by the hour, day, or month, with browsable packages and promotional offers.
What Clients Say
Reviews from Upwork and Mostaql clients across shipped Flutter projects.
"It was a pleasure working with Engineer Sarah, who demonstrated exceptional professionalism, creativity, and outstanding skills in Flutter application development and problem-solving. Her strict adherence to deadlines and attention to detail resulted in excellent performance that exceeded expectations."
A wonderful experience working with Engineer Sara. She brings real team spirit and adds genuine value to the work, handling challenges professionally and delivering creative, precise solutions with speed.
I'd started this project with another freelancer who never finished it, so I was hesitant — but choosing Engineer Sara made all the difference. Rare professionalism, fast communication, and thoughtful ideas that added real value. I highly recommend working with her again.
A highly skilled and professional developer — comfortable to work with, cooperative, and quick to respond, all while staying fully committed to deadlines. I'll definitely work with her again on future projects.
I want to thank Engineer Sara Salem for the high level of professionalism and dedication she showed. Her outstanding performance and commitment made her fully deserving of the appreciation and recognition she received from us.
I recommend working with her — professional, cooperative, and sincere in handling the project from start to finish.
