01About Me

The person behind the code

Muhammad Uzair — Senior Flutter Developer and Mobile Engineering Lead
4+Years
Open to new opportunities

I believe the best mobile apps are those where the technology completely disappears, leaving only the experience.

I approach every project with a product-first mindset — obsessing over user experience before writing a single line of code. My work spans the full lifecycle, from architecture whiteboard sessions to App Store deployment, always anchored in clean code and scalable patterns.

My technical foundation rests on clean architecture (MVVM, MVC), state management mastery (Provider, GetX, BLoC), and deep integration experience — REST APIs, Firebase, SQLite, OpenAI APIs, Google Maps, geofencing, and push notifications. I build systems that are maintainable by teams, not just by me.

Beyond engineering, I think deeply about system design, product strategy, and user delight. I'm equally comfortable leading cross-functional collaborations, implementing agile workflows, and mentoring junior developers. Every shipped app reflects a commitment to craft over speed.

How I approach the work

09FAQ

Frequently asked questions

Everything you need to know about working together, delivery timelines, and project handover.

01What does your typical project development workflow look like?

We kick off with a technical scope alignment call to define requirements and milestones. From there, I structure the application architecture (BLoC/Clean Architecture), deliver weekly testable APK / TestFlight builds, maintain transparency via GitHub, and finalize with App Store and Google Play submissions.

02How do you manage communication across different timezones?

I am based in PKT (UTC+5), which allows 4–6 hours of direct working overlap with European (GMT/CET) and Middle Eastern (GST) business hours, and morning/evening alignment windows with US East (EST) and West (PST) teams. I provide daily async Loom/Slack updates and weekly progress demos.

03What engagement and pricing models do you offer?

I work under two flexible models: (1) Fixed-Scope Milestone Contracts for MVPs and audits with well-defined specifications, and (2) Weekly Dedicated Sprint Retainers for evolving products requiring continuous feature delivery and team leadership.

04Do you handle App Store and Google Play deployments and compliance?

Yes. Every project includes end-to-end release management: configuring Apple Developer / Google Play Console accounts, setting up provisioning profiles, adhering to strict privacy and permission guidelines, and addressing any reviewer feedback until public release.

05Who owns the code and intellectual property once completed?

You retain 100% full intellectual property ownership. All source code, Git repositories, Firebase configurations, and design assets are transferred completely upon milestone completion under standard commercial IP terms.

06Can you take over or refactor an existing, buggy Flutter codebase?

Absolutely. I frequently conduct codebase health rescues: profiling frame rate drops, resolving state management entanglements, upgrading deprecated packages, and restructuring code to clean architecture without having to rebuild from scratch.
