I find what slows people down — and build it out of their day.

I’m Abdelrahman — a Flutter developer who starts every app from a real problem, not a framework. Clean architecture underneath, a calm interface on top.

The approach

Apps start as problems,
not features.

Every app here began with a moment of friction — a parent missing a dose, a day that vanished without a trace, a to-do list too rigid to be useful. I don’t start with “what can Flutter do.” I start with “what’s getting in this person’s way,” then engineer until it’s gone.

01

Start from the problem

I map the real friction before writing a line of code, so the app solves something that actually matters to the person using it.

02

Engineer the edge cases

No connection, a failed request, a race condition — the moments most apps ignore are the ones I design for first. That’s where reliability lives.

03

Build for the real user

Often that’s a tired parent or an older relative. Accessibility and clarity aren’t polish on top — they’re the point of the whole thing.

Selected work

Five products. Each one
started with a real problem.

The friction

A mother is tracking medication for three kids. The doses differ, the schedules overlap, and one afternoon a course gets stopped early — the kid looked better, so why keep going? Two weeks later it’s back, worse.

The insight

The person using this app is usually caring for someone else — often several someones. So multiple profiles aren’t a feature, they’re the foundation. And since the user might be a tired parent or an older grandparent, accessibility isn’t optional — it’s the entire brief.

What I built

Separate care profiles, per-person schedules, timezone-precise reminders that survive reboots, and adherence reports you can actually act on — wrapped in a calm, high-readability interface tuned for older eyes.

Under the hood
FlutterDartBLoCHiveflutter_local_notifications
  • Offline-first by design. All schedules cached locally with Hive, so reminders keep firing with zero connection.
  • Precise, resilient scheduling. Timezone-aware notifications with exact-alarm scheduling — doses land on time even across reboots and DST shifts.
  • Full CRUD over complex regimens. Multi-dose, multi-profile prescription schedules with per-person adherence tracking and reports.
  • Accessibility as architecture. Type scale, contrast and touch targets tuned for older users from the ground up, not bolted on.

MedCare Telemedicine + pharmacy
The friction

Healthcare is scattered — history in one place, appointments in another, the pharmacy somewhere else, and no easy way to ask a simple medical question. MedCare pulls it into a single app for three kinds of people at once: patients, doctors and pharmacies.

The engineering bet

Build a full multi-role platform with real business logic and zero paid backend — staying entirely on Firebase’s free tier by turning security rules themselves into the backend.

What I built

Patients get medical history, appointment booking, a pharmacy to buy from, and an AI assistant for simple questions. Doctors manage their appointments. Pharmacies run full inventory. Three roles, one codebase, no server bill.

Under the hood
FlutterFirebase AuthCloud FirestoreProvider / ChangeNotifierFastAPIREST
  • Security rules as backend. Complex Firestore rules enforce role-based access (patient / doctor / pharmacy) and let patients atomically decrement inventory with FieldValue.increment while categorically rejecting any tampering with prices or metadata.
  • Zero-cost cloud architecture. Deliberately migrated from local SQLite to a fully cloud-backed system while holding a strict no-paid-Cloud-Functions constraint on the Firebase Spark tier.
  • Reactive, flicker-free state. Composed multiple domain stores over live Firestore snapshots() streams with explicit loading states — a real-time UI without the flashes.
  • Self-hosted AI over typed REST. A custom FastAPI medical assistant on Railway, called through a typed JSON client that handles conversation context, timeouts and graceful typing / failure states.
  • Backend-free push. Appointment and medication reminders via Firestore listeners + local notifications instead of FCM — keeping the zero-cost promise intact.

The friction

Most to-do apps are either too dumb to categorize anything, or so bloated with features you spend more time fighting the tool than doing the work. Sprinto is the middle: organized, fast, premium to touch, and nothing you don’t need.

The engineering bet

Ship a full-stack product where the hard parts are invisible — a real auth system and offline support that just work, so the app always feels instant and never logs you out mid-session.

What I built

A Flutter client on a custom FastAPI backend: projects and tasks with status and priority, real-time search, offline mode, light/dark theming, and a glassmorphism design system — all backed by a targeted test suite.

Under the hood
FlutterBLoC / CubitDiogo_routerget_itfreezedHiveFastAPIJWT
  • Custom auth backend. FastAPI with JWT access/refresh tokens, refresh-token rotation and server-side revocation, deployed to a cloud host.
  • Single-flight token refresh. A Dio interceptor that catches concurrent 401s with a deduplication guard — no redundant refresh calls, no mid-session logouts — with unit tests written for the concurrency paths specifically.
  • Clean Architecture, enforced. Strict inward dependencies (presentation → domain ← data) with a pure-Dart domain. Proof it paid off: offline caching was added entirely inside the data layer without touching UI or business logic.
  • Optimistic updates with rollback. Mutations feel instant, then auto-revert on failure so the UI never drifts from the server.
  • Design system, not just styles. A reusable glassmorphism system with theme-aware tokens via Flutter ThemeExtensions, full light/dark.
  • Tests where they matter. Focused on failure paths — refresh concurrency, optimistic rollback, cache fallback — over chasing coverage. Clean, phased Git history with conventional commits.

“Where did my day go?” You can’t fix a habit you can’t see. Heft makes you track what you’re actually doing right now — the first real step to taking your time back.

What I do

The same tools,
aimed at outcomes.

Frameworks are table stakes. What clients actually hire is the judgment about how to use them. Here’s what that looks like.

Product thinking

where every project starts

I translate a fuzzy problem into a product decision. The reason my apps feel focused is that I decide what not to build as carefully as what to build.

Architecture that scales

Clean Architecture · feature-first

Layered, testable, easy to extend without fear. Proof: added offline caching to Sprinto entirely in the data layer — UI and logic untouched.

Flutter craft

design systems · motion · a11y · RTL

Custom design systems with theme tokens, fluid animation, and interfaces built for real people — including full Arabic / right-to-left support.

Backend & cloud

FastAPI · JWT · Firebase

I build the API too when it’s needed — custom FastAPI services with proper auth, or cost-optimized serverless on Firebase that runs a real product for free.

Offline-first reliability

Hive · optimistic UI · graceful failure

Apps that stay fast and honest with no connection: local caching, instant optimistic updates with rollback, and failure states that tell you what to do next.

Abdelrahman Eldaly

I studied Computer & Information Science at Ain Shams University, which gave me the fundamentals most self-taught developers spend years back-filling — data structures, systems thinking, the why behind the framework.

Then I spent over two years as a technical instructor at iSchool, teaching engineering concepts to other people. That’s the part clients tend to value most: I explain technical decisions clearly, I communicate on time, and I don’t disappear. If you’ve ever worked with a developer who couldn’t tell you what they were doing, you already know how rare that is.

Everything I build comes back to one instinct — notice the friction in someone’s day, then engineer it away. That’s what turns an idea into an app people actually keep.
