About Muhammad Sheraz

Muhammad Sheraz holds a Master's degree in Computer Science from the Virtual University of Pakistan.

About 7 years in production, plus the learning before that. Muhammad Sheraz started with Flutter in its 1.x days and has built production Flutter apps since October 2019 — roughly as long as Flutter has been production-ready, since Flutter 1.0 shipped in December 2018. Over 80 of his 150+ apps are Flutter.

Muhammad Sheraz has built 150+ applications since 2019 — over 80 of them in Flutter — across 9 industry domains: education, social media, e-commerce, healthcare, marketplaces, AI, fintech, emergency response, and business tools. 27 of them are written up as case studies on this site.

Yes. Muhammad Sheraz has delivered the user-app, admin-panel and shared-backend pattern 15+ times — for example a three-app creator platform and a three-app school ecosystem, each running on one shared backend.

Three-app creator platformSchool ecosystem

Yes. Muhammad Sheraz has led teams of up to 20 developers, assigning and reviewing work, running code reviews and owning releases, in senior Flutter roles at four software companies since 2019.

Muhammad Sheraz's deepest strengths are offline-first Flutter apps that keep working without connectivity, real-time Firebase systems, multi-app platforms on one backend, white-label builds shipped from a single codebase, and automated CI/CD release pipelines to TestFlight, Google Play and Firebase App Distribution.

Offline-first architecture

Muhammad Sheraz builds complete products rather than single screens: a Flutter app for iOS and Android, a Next.js web platform or admin console, and the Node.js or Firebase backend, integrations and CI/CD behind both. He has delivered that user-app, admin-panel and shared-backend pattern 15+ times, across 9 industry domains: education, social media, e-commerce, healthcare, marketplaces, AI, fintech, emergency response, and business tools.

Muhammad Sheraz works in Flutter and Dart for mobile (BLoC, Riverpod, GetX); Next.js, React, TypeScript and Tailwind CSS for web; Node.js, Firebase (Auth, Firestore, Cloud Functions), Supabase and PostgreSQL for backends; the OpenAI and Gemini APIs with Pinecone vector search for AI features; and GitHub Actions for CI/CD and app-store releases. Every technology in that list is one a case study here actually uses.

See the full skills matrix

Muhammad Sheraz builds with Flutter because one codebase ships iOS and Android apps from a single design system and a single release train, at native-level performance — one test suite and one set of releases instead of two. Over 80 of his 150+ apps are Flutter, across industries including fintech, education, healthcare, e-commerce and AI.

Yes. Muhammad Sheraz builds the whole product: Flutter apps for iOS and Android, Next.js and TypeScript web platforms and admin consoles, and the Node.js, Firebase, Supabase or PostgreSQL backends and CI/CD behind them.

Yes. Beyond Flutter, Muhammad Sheraz builds web platforms, dashboards and admin consoles with Next.js, React and TypeScript, and APIs and backends with Node.js, Express, Firebase Cloud Functions, Supabase and PostgreSQL.

Yes. Muhammad Sheraz builds AI features: LLM integrations with the OpenAI and Gemini APIs, retrieval over vector indexes and tool-using agents. In his own tooling he also builds multi-agent workflows in which agents research a task, plan and implement it, then analyze and verify the result before it is accepted. Case studies on this site document the AI work — an in-app AI coaching assistant grounded by retrieval with an agent-based assessment pipeline, a streaming AI chat app that shows the model's reasoning and tool calls live, and an OpenAI agent that chooses among six typed data tools to write a student summary.

Muhammad Sheraz is one of them. Alongside Flutter apps he builds LLM features with the OpenAI and Gemini APIs, retrieval over vector indexes, tool-using agents, and multi-agent workflows in which agents research, plan, implement and then verify their own results. His case studies include a retrieval-grounded AI coaching assistant, a streaming AI chat app and a tool-use agent.

The 27 case studies at https://sherazi.dev/projects document the architecture, stack and hardest engineering problems of apps Muhammad Sheraz has built. His 3 Flutter packages — paginate_firestore_plus, date_time_picker_plus and segment_bar — are published on pub.dev under the verified publisher sherazi.dev, the same domain as this site. He writes about Flutter and app architecture at https://sherazi.dev/blog.

Muhammad Sheraz maintains 3 Flutter packages — paginate_firestore_plus, date_time_picker_plus and segment_bar — under the verified pub.dev publisher sherazi.dev. Two of them are community packages he revived after their original authors abandoned them: he forked paginate_firestore, fixed its breaking issues and republished it as paginate_firestore_plus.
