Things I designed, built and shipped.

Sole developer and architect, end to end.

• Core accounting — double-entry ledger over transactions, accounts, journal templates and balanced postings, with multi-currency FX rates, revaluation runs and auto-balanced FX trading P&L.
• Reporting & compliance — trial balance, balance sheet, income statement, cash flow and P&L, plus AML flagging, audit trails and tax handling.
• Multi-tenant SaaS — row-level security and least-privilege database roles with user memberships, role management and tokenised invite links.
• Multi-platform client — one Flutter codebase on iOS, Android, macOS, Windows and Web; offline-first via Drift/SQLite with real-time sync and conflict handling.
• Backend & DevOps — Dart/Serverpod API of roughly 30 endpoints, deployed on Fly.io with Docker, Cloudflare and GitHub Actions CI/CD.

Senior Flutter developer.

• Architecture & scale — production app of roughly 950 Dart files spanning a social feed, marketplace, real-time chat and a peer-to-peer job-exchange module ("Hand2Hand"), shipped to iOS and Android.
• Real-time chat — WebSockets plus Firebase (Firestore, Realtime DB, FCM) for live messaging, delivery and read receipts, and push notifications.
• AI job matching — in-app assistant for job-offer search and matching with conversational search and persistent chat history.
• Native plugins & media — two in-house Flutter plugins wrapping a licensed video-editing SDK and a real-time face-filter engine, plus speech-to-text and video trimming.
• Commerce & social — multi-vendor storefronts, cart and checkout, wallet and instalment payments, QR-verified live draws, and a full social layer of posts, stories, short video and challenges.
• Engineering — GetX for state, DI and routing across 100+ screens; Dio with custom interceptors; bilingual Arabic/English RTL localisation; Firebase Auth, Crashlytics and Analytics.

Full-stack developer · built and maintained solo across ~20 months.

• Platform — Laravel 11, Filament 5 and Inertia + React managing clients, suppliers, banks, fund boxes and system accounts with date-based exchange-rate conversion.
• Transaction engine — transfers, internal transfers, income and expense, payments, currency exchange and opening balances, with soft-delete reversal handling and an immutable audit log.
• Access control — role-based permissions (Spatie) with per-resource, per-action authorisation for finance staff, cashiers and admins.
• Offline-first capture — pending transactions cache locally during connectivity loss and auto-sync via REST on reconnect.
• Reporting & API — bearer-token REST API with a consistent JSON contract, plus PDF and Excel export pipelines for reports, balance sheets and vouchers.

Solo developer · cross-platform.

• Architecture — feature-first, thin-UI/fat-repository structure with Riverpod state management and go_router navigation.
• Auth & backend — multi-provider sign-in (email, Google, Apple) on Firebase with Firestore, Auth, Crashlytics, Analytics and App Check; offline-first via Drift/SQLite and Hive.
• Training — workout templates, live active-workout tracking backed by Firestore, and a progress dashboard charting body-metric trends.
• Nutrition — food search, macro tracking and daily summaries, plus an AI coaching feature with usage limits and in-app-purchase upgrade prompts.
• Testing — unit and widget tests with mocktail and fake_cloud_firestore, UI kept decoupled from data sources.

Tasks, budgeting and work-hours tracking unified into one tool.

• Architecture — GetX for reactive state and Hive for local-first offline storage, with model-based persistence across transactions, tasks and work sessions.
• Budget intelligence — per-category monthly budgets, real-time 80%/100% threshold alerts, and month-over-month spend variance insights.
• Task system — Eisenhower matrix quadrants wired into a streak-based dashboard that combines task completion with budget adherence.
• Time-to-money — hourly-rate work tracking that converts logged hours into income postable directly to the budget.
• Native widgets & sync — Android home-screen widgets in Kotlin, QR-based data transfer, local AES encryption, and Firebase Realtime Database for exchange-rate sync.

Privacy-first, fully offline: multilingual content, habit tracking, local reminders and native widgets.

• Architecture — no backend at all; clean separation of content, state and UI, with counters, streaks, bookmarks and settings persisted locally.
• Localisation — content across six languages with automatic English fallback and full RTL layout for Arabic and Urdu.
• Content pipeline — integrated the open-source Hisn al-Muslim dataset through a normalisation pipeline mapping source categories to the app schema and filtering corrupted machine-translation entries.
• Notifications — local reminders with timezone-aware, exact-alarm scheduling on Android 12+, deep-linking from a notification into the relevant collection.
• Native widgets — Android App Widget in Kotlin and iOS WidgetKit via Swift TimelineProvider, showing an auto-rotating dhikr without opening the app.
