Full-stack POS & inventory platform with offline-first sync
A POS and inventory management platform: a Node.js/TypeScript REST API on PostgreSQL paired with a Flutter app that keeps working offline and syncs when connectivity returns.
A rental-only listings platform rebuilt around a branch-based, role-scoped backend
A branch-managed rental marketplace connecting tenants with branch offices — a Next.js web platform plus a Flutter mobile app sharing one Supabase backend, with real-time messaging, commission tracking and full audit logging behind role-scoped admin and branch panels.
Social sports platform — live NFL/NBA scores, friendly wagers & group chat
A feature-dense social sports app where friends track live NFL/NBA scores and news, challenge each other with 'gages', climb leaderboards and talk trash in group chat — with push notifications and deep links throughout.
Field-sales order app for medicine distribution
A Flutter field-sales app for medicine distribution: sales reps browse a medicine catalog, take store-by-store orders with quantity, discount and bonus fields, and sync a local SQLite ledger to Firebase for backup and recovery.
AI chat that streams replies live — with visible reasoning, tool calls and a multi-provider model catalog
A Flutter AI-conversations app where every reply streams over a live WebSocket connection, with the model's reasoning steps and tool calls (web search, automatic model routing) visible as they happen. Sign-in is a passwordless magic link — the app is usable as a guest before that — and users pick from a searchable, multi-provider model catalog with free and premium tiers.
Creator-economy platform — fans commission personalized videos from celebrities, celebrity and admin apps
A three-app creator-economy platform: a fan app where users commission a personalized video message from a celebrity for a specific occasion and pay through an integrated bank payment gateway, a celebrity app for recording and delivering the video and managing bank withdrawals, and an admin console with a 14-permission role system — all three sharing one Firestore backend.
AI-assisted coaching platform — student app, admin console, and a multi-provider AI backend
A Flutter learning and personal-development platform built as a student app and an admin console over one Firestore backend, with an in-app AI assistant — chat, per-lesson summaries and recommendations — powered by a dedicated OpenAI/Gemini/Groq backend with vector search over the course library.
Three coordinated apps, one shared backend
A school-management platform built as three coordinated Flutter apps — a student/parent app, a teacher professional-development app and a staff operations app — sharing account and content infrastructure, with a standalone AI prototype exploring automated student-performance summaries.
Web POS for fuel retail — meter-reading sales entry, inventory & reports
A Flutter Web point-of-sale system for fuel retail: a daily closing form that turns per-nozzle pump readings into sales and atomically updates fuel and shop-item stock, plus two Firestore-backed sales reports, all behind an admin-gated Firebase login.
Role-based POS with vendor/customer ledgers for small retail businesses
A Flutter POS and back-office system for small retail businesses — Admin/Cashier roles, a two-pane checkout terminal with partial/credit payments, and running vendor and customer ledgers, all on a real-time Firestore backend across web, Android and iOS.
Short-video social app — camera-to-feed reels, live rooms and a creator coin economy
A Flutter short-video social app: an in-app camera records reels with a searchable sound library, a vertical feed carries hashtags, follow, like and comment, and a coin economy lets users recharge with card payments or native in-app purchase and gift coins to creators, who withdraw them — all behind a Node/Express/MongoDB backend and a Next.js admin console, with AI content moderation on every upload.
Two-sided sports-ground booking — partner and player apps
A two-sided Flutter marketplace for sports-ground bookings: a partner app where venue owners manage grounds, weekly slot templates and incoming reservations, and a player app for browsing grounds, picking hourly slots on a calendar and tracking payment status — both sharing one Firestore backend.
A line of KYC-gated crypto wallet apps built on one hardened architecture
A line of Flutter crypto-wallet apps sharing one architecture: KYC document capture, PIN-secured send/receive, live market charts and a dedicated REST backend per app.
3 published pub.dev packages under a verified publisher
I maintain three published Flutter packages on pub.dev under the verified publisher sherazi.dev — the same domain as this site — including paginate_firestore_plus, which I revived after the original was abandoned.
Encrypted 1:1 and group chat, self-destructing messages, and an approval-gated admin console
A Flutter chat app and a companion Flutter admin console sharing one Firestore backend: message data is encrypted client-side before it is stored, conversations carry an adjustable 1-6 day self-destruct timer, the chat screen blocks screenshots and screen recording, and idle sessions auto-log-out after 5 minutes.
A timed Firestore quiz engine, PDF handout library and study-group directory for distance-learning students
A solo-built Flutter app for Virtual University of Pakistan students: a category-driven quiz engine pulling randomized, timed questions from Firestore, plus browsable handouts, past papers and assignment solutions delivered as cached PDFs, alongside a WhatsApp study-group directory and video-lecture links.
A category-browsable food-ordering app with a live Google Places address picker, plus a matching admin catalog console
A Flutter food-ordering app — browse a menu by category, build an order through per-item variations and modifiers, and check out with a Google Places-autocomplete address picker and a live Google Map marker — paired with a separate Flutter admin console for managing the menu catalog and user accounts over the same Firestore backend.
A football match-prediction feed backed by an admin bulk-data pipeline
A two-part Flutter platform: an Android app that streams football match-outcome predictions — win/draw probabilities, BTTS and over/under goal chances — segmented into upcoming, in-play and past fixtures from a live Firestore feed, paired with a Flutter Web admin console that bulk-imports match data from CSV, JSON or XLSX files and deploys to Firebase Hosting through its own GitHub Actions pipeline.
A personal health-tracking app — multi-metric dashboards, body-system browsing, and doctor-appointment booking
A Flutter personal health-tracking app: blood glucose, blood pressure, weight, food, exercise, mood and sleep each get their own fl_chart/echarts-based analytics screen across a 10-tab dashboard, alongside a 'Health Avatar' screen for browsing records by anatomical body system and a clinic/doctor appointment-booking flow with government/private clinic selection. Built as a UI-first prototype.
A social fitness tracker — Mapbox route recording, live group tracking, and a full social layer built on top of it
A Flutter social-fitness app: Mapbox-based route recording for workouts, live on-map tracking of other users nearby, Bluetooth pairing with cycling sensors for speed/cadence, and a social layer — activity feed, posts, chat, follow/friend requests, and report/block moderation — all built on GetX with 14-language localization.
A public water-quality dashboard — an interactive grade-coded map, trend charts and a heatmap over live field data
A Next.js web dashboard for community-collected water-quality data — an interactive Leaflet map with A–F grade-coded markers and a heatmap mode, multi-parameter trend and comparison charts, and region/date/grade filtering, reading from a shared Firestore collection.
A citizen-science field app — wildlife sightings and water-quality sampling, logged with GPS and reviewed through a built-in admin console
A Flutter citizen-science app with two observation tracks: wildlife sightings (photo, a species picker sourced from an admin-managed list, a self-reported confidence rating, GPS location) and water-quality sampling (a detailed chemistry form plus manually assigned site/region/watershed A-F grades). A shared map plots both, and a 5-tab admin console in the same codebase handles moderation, species management and user blocking.
A podcast app with per-episode comprehension quizzes — background playback, local favorites, and a scored quiz history
A Flutter podcast app: search and browse a live third-party podcast catalog, play episodes with a persistent background audio player and lock-screen controls, and — for episodes carrying an authored quiz in Firestore — take a scored multiple-choice comprehension quiz with instant right/wrong feedback. Favorited shows and completed-quiz scores are tracked locally on-device, browsable later in a dedicated quiz-history screen.
A personal sexual-health record app — STI test tracking, birth-control history, and a one-tap summary of what others will see
A Flutter personal health-record app: a user logs STI/STD lab test results, birth-control methods and disease-prevention/surgery history, all summarized on a dedicated 'Preview' screen framed as "what others will see" — the app's central value proposition, not a generic patient dashboard. Firebase-backed, with email and SMS phone verification and Firestore-synced records.
Emergency SOS alerting with a role-based live-dispatch console
A Flutter emergency-SOS app that fires a live, location-tracked alert across six emergency categories — with a native call/SMS fallback alongside the in-app channel — paired with a role-based Flutter Web console for live monitoring, dispatch logging and chat, backed by a TypeScript Cloud Functions layer that routes push notifications by admin role.
An AI-agent prototype that turns a student's attendance, notes and grades into one narrative teacher-facing summary
A TypeScript backend prototype built around one idea: give a teacher a single narrative overview of a student — strengths, gaps, and next steps — generated by an OpenAI agent that decides which of six data tools to call (student info, attendance, notes, grades, assessment results, attendance register) rather than being handed one flat prompt.
Location-based social network — friends, groups, crowd-voted event meetups, and a dedicated gamification backend
A Flutter social-networking app built around a friend graph, groups and a 'Moments' photo/video feed, with events discovered through Firestore geo-radius search and resolved by attendee voting — a venue poll and a fees poll that auto-tally and close on schedule — all backed by a dedicated Firebase Cloud Functions service that runs the app's points-and-levels gamification layer.
