Health / Emergency · 2025 · Live
Blood Donors 243 GB
Offline-first emergency blood-donor locator for rural Pakistan
A free, open-source emergency blood-donor locator built for rural Pakistan (village 243 GB) where connectivity is intermittent. Search donors by blood group and distance, see availability, and reach them in one tap over WhatsApp or a call. The headline is the architecture: an offline-first stack on HydratedBloc + Supabase — cached donors render instantly on launch with no spinner, a background incremental sync pulls only records changed since the last sync, and writes made offline queue in a persistent sync queue (with retry) that auto-flushes the moment connectivity returns. Fully localised in Urdu (RTL) and English.
Why Make finding a matching blood donor possible at 2 AM on a 2G connection — the app has to work fully offline and sync silently when the network returns.
Built with
- Flutter
- flutter_bloc + HydratedBloc
- Supabase
- connectivity_plus
- go_router
- Urdu / English (RTL)
Features
- Search donors by blood group + distance
- One-tap WhatsApp & call
- Offline-first — cached list loads instantly, no spinner
- Incremental background sync (changed records only)
- Persistent offline write queue, auto-retry on reconnect
- Urdu (RTL) + English, register-as-donor flow

Social / Discovery · 2021 · Shipped
Social Groups
Browse & join WhatsApp groups by category — plus a scam-reporting board
A WhatsApp group discovery app (android:label "Social Groups"). Users browse curated groups by category (Food, Funny, Sport, Travel, Education and more), open any group for its info and member count, and join in one tap. A community "Scammers" board lets people report and look up known scammers, and anyone can submit a new group or scammer entry with name, link and description. A companion admin app ("Grouper Admin") reviews and approves pending group/scammer submissions, manages categories, and configures the ad units remotely.
Why Make it easy to find trustworthy WhatsApp groups by interest while warning the community about known scammers.
Built with
- Flutter
- BLoC + HydratedBloc
- Firebase (Firestore + Storage)
- AdMob + AppLovin MAX
- go_router
Features
- Browse groups by category
- Group detail + one-tap join
- Community scammer board
- Submit a group or scammer (admin-approved)

E-Commerce · 2023 · Live
YouShopper
A three-app multi-vendor marketplace — shop, sell & deliver
A complete multi-vendor marketplace built as three separate Flutter apps, all live on Play Store. The Customer app is a full storefront — categories, brands, flash deals, club points and an in-app wallet, with 10+ payment gateways (Stripe, PayPal, Razorpay, bKash and more) and live order tracking on a map. The Seller app is a vendor dashboard with sales analytics, product and order management, commission history and withdrawals. The Delivery app is a last-mile pickup tool with assignment, live map tracking and earnings. Firebase messaging, Google Maps and social login run across all three.
Why Give a cold-logistics marketplace its own end-to-end commerce stack — shopping, selling and delivery — instead of renting three off-the-shelf apps.
Built with
- Flutter
- Provider + GetIt
- Firebase Messaging
- Google Maps
- Multi-gateway payments
- i18n localization
Features
- Customer storefront — categories, brands & flash deals
- 10+ payment gateways (Stripe / PayPal / Razorpay / bKash…)
- Club points & in-app wallet
- Seller dashboard — sales analytics, products, commissions
- Delivery app — live map tracking & earnings
- Firebase push, social login & multi-language

Status Saver / Downloader · 2024 · Shipped
Status Getter
Save WhatsApp statuses (Android SAF) + paste-URL video downloader
A status saver and all-in-one video downloader. It reads WhatsApp and WhatsApp Business statuses into a gallery so users can save any photo or video — built on Android's Storage Access Framework via a native Kotlin SAF handler for scoped-storage compliance on Android 11+. A separate "All Video Saver" pastes any link (TikTok, YouTube, Facebook, Instagram and more) and downloads it in a chosen quality and format, extracting through an in-app WebView + savefrom-style scraper. Thumbnails are generated off the UI thread with Dart isolates; Material-3 green dual-theme, AdMob configured from Firestore, open-source on GitHub.
Why One app to keep the statuses worth remembering and grab any video by link — without watermarks or a separate downloader per platform, while staying Play-Store compliant on modern Android.
Built with
- Flutter
- BLoC + HydratedBloc
- Storage Access Framework (native Kotlin)
- InAppWebView scraper
- Dart isolates
- Firebase + AdMob
Features
- Save WhatsApp & WhatsApp Business statuses
- Scoped-storage compliant via Android SAF (Android 11+)
- All Video Saver — paste link (TikTok / YouTube / FB / IG / …)
- Quality / format picker
- Off-thread thumbnail generation (Dart isolates)
- Material-3 green light / dark theme

YouTube Marketing / Coin Economy · 2026 · Live
YT Master
Two-sided YouTube growth marketplace — API-verified earning, live demo
A two-sided YouTube growth marketplace spanning a user app ("YT Master", in-app brand "ProBooster") and a claim-gated admin panel — shipped in 2021, then given a major 2026 modernization and security overhaul, now live as Flutter web demos. Members earn coins by genuinely watching (anti-cheat playback-position tracking — seeking, stalling, backgrounding or 2x speed earns nothing) and subscribing, with every claim verified against the member's own YouTube account via the YouTube Data API — no honor system. Coins fund view / subscriber / watch-time campaigns that settle in atomic Firestore transactions, top up through local rails (Easypaisa / JazzCash / bank) with admin approval, and flow through a channel marketplace and referral codes. The admin panel adds a live-KPI dashboard, order review, user management and catalog editors behind a Firebase admin claim — including a public view-only demo login — all on a deliberately zero-paid-backend architecture with deployed Firestore rules smoke-tested by 46 automated assertions.
Why Give creators a one-stop marketplace to grow their channels — rebuilt so every reward is verifiably earned and the whole economy runs without a paid backend.
Built with
- Flutter
- Provider + go_router
- Firebase (Auth + Firestore + Rules)
- YouTube Data API v3
- youtube_player_iframe
- ThemeExtension design tokens
Features
- Watch & Earn with anti-cheat playback-position tracking
- Subscribe & Earn verified via YouTube Data API — no honor system
- Campaigns settle in atomic Firestore transactions
- Coin store via Easypaisa / JazzCash / bank + admin approval
- Channel marketplace & referral codes
- Admin: live KPIs, orders, users, catalogs — public view-only demo

Utility · 2021 · Shipped
Bill Checker
Check Pakistani utility bills — electricity, gas, phone & water
A utility-bill aggregator for Pakistan. Tabs for WAPDA (electricity), Gas, Phone and Water list every regional provider — LESCO, FESCO, SSGC, SNGPL, the city Water & Sanitation Agencies and more — and tapping one opens that provider's official bill-inquiry portal in an in-app browser to fetch the latest bill. Ships with a light/dark theme toggle and AdMob monetization.
Why Put every Pakistani utility bill-inquiry portal behind one app so people stop hunting for each provider's website.

Home Services · 2023 · Live
Nakoda Urban Services
On-demand home services for India — cleaning, AC & pest control
The customer app for Nakoda Urban Services, a home-services marketplace in India covering cleaning, AC servicing and pest control. Delivered as a Flutter app wrapping Nakoda's mobile booking platform, hardened with native plumbing: a video splash, OneSignal push that deep-links straight into the right service page, Firebase Analytics and Crashlytics, Google Play in-app updates, and a branded navigation drawer linking every service category, the blog and the partner login.
Why Give Nakoda's customers a fast, installable booking app with reliable push and seamless update delivery — beyond what a plain mobile site offers.

Calculator
Open-source Material You calculator — scientific mode, every platform
A polished cross-platform calculator, now open-source (MIT) and live on the web. Standard and scientific modes ride a real expression engine (math_expressions) with Samsung-style percent semantics (200 + 10% = 220), smart thousands-grouped formatting, and a persistent day-grouped history with undo. Material You dynamic theming, adaptive phone / tablet / desktop layouts, full keyboard support and haptics round out the front end — rebuilt from GetX to Riverpod 3 for the public release. The original client build pairs it with a Firebase backend: ad units configured remotely from Firestore and a companion admin app that manages users, balances and withdrawal payouts (mobile-only, cleanly gated out of desktop/web builds).
Why Ship a genuinely useful calculator whose ads and reward payouts are fully controllable from a backend — then open-source the modernised app as a portfolio-grade Flutter showcase.
Built with
- Flutter
- Riverpod 3
- math_expressions
- Material You (dynamic_color)

- AdMob (remote config)
Features
