Flutter app development, rescue, and maintenance
Most projects start in one of three places: there's no app yet, there's an app that's struggling, or there's a live app that needs a dependable developer. Pick the one that sounds like you.
Build a new app
A first version built quickly and carelessly gets expensive fast. Features start breaking each other, releases slow down, and within a year someone suggests a rewrite.
Founders with an idea or designs and no mobile team, companies adding a mobile product, and agencies that need a senior Flutter developer for a client build.
Plan your new appI turn your designs or spec into a production Flutter app for iOS and Android from one codebase. I plan the architecture first: how state is managed, how the app talks to your backend, and where integrations like payments or real-time chat fit. Then I build in milestones you can install and test, and take the app through App Store and Google Play review.
- 1Scope call: what ships first, what waits, how we'll measure it
- 2Architecture and a milestone plan
- 3Builds on TestFlight and Google Play internal testing as features land
- 4Store submission, review fixes, and launch
- 5Handover with documentation, or straight into maintenance
What you get: A production app on both stores, a clean repository you own, setup notes for your next developer, and a codebase that won't need rewriting when you grow.
Rescue an existing app
The app crashes, screens lag, builds fail, or a feature that should take a day takes two weeks. Often the original developer has moved on and nobody fully understands the code.
Product owners and founders with a Flutter app that's buggy, slow, unstable, or hard to change, and teams that inherited a codebase from an agency or freelancer.
Get your app auditedI start with an audit, not a rewrite. I go through crash reports, profile slow screens, review state management and API handling, check dependencies and Flutter version, and get the build pipeline working. You get a written list of problems ranked by how much they hurt users. Then I fix them in that order, improving structure as I go so the app keeps shipping.
- 1Audit: code review, crash and performance analysis, written findings
- 2Stabilize: crashes, blocking bugs, and anything stopping store review
- 3Improve: untangle state, fix API handling, cut unnecessary rebuilds
- 4Resume regular releases, with you deciding what comes next
What you get: A clear picture of what's wrong and why, a stable app, a faster release cycle, and a codebase another developer could pick up.
Keep a live app moving
Your app is live and people use it, but features pile up, iOS and Android updates break things, and there's no one dependable to own the Flutter side.
Startups after launch, companies whose original developer left, and agencies with apps in long-term support.
Discuss ongoing supportI work as your Flutter developer on a monthly basis. New features, bug fixes, Flutter and dependency upgrades, OS changes, store releases, and performance work, prioritized with you each cycle.
What you get: A dependable owner for your Flutter code, predictable releases, and an app that keeps up with iOS, Android, and Flutter changes.
The parts that usually go wrong
Whichever way a project starts, these are the areas I'm most often brought in for.
Performance and stability
Slow screens, excessive rebuilds, janky scrolling, memory problems, crash spikes, and poor API handling. I profile first, then fix the actual bottleneck instead of guessing.

Every project is quoted after a short scope call, so you pay for what your app actually needs.
Fixed-scope project
A defined set of features, a timeline, and a price agreed up front. Best for new builds and single features.

A short, paid review of an existing codebase with a written report and a prioritized fix list. The usual first step for rescues.

A reserved block of my time each month for features, fixes, and releases. Best for live apps that need an ongoing owner.

What time zone do you work in?
Pakistan, UTC+5. That overlaps with European working hours and US mornings. We agree on shared hours at the start of each project.
Do you design the app too?
I build from your designs, usually in Figma. If you don't have designs, I can work with a designer you choose or recommend one.
Who owns the code?
You do, from the first commit. The code lives in your repository, and the app is published under your developer accounts.
Can you join our existing team?
Yes. I can work inside your repository, your process, and your tools, alongside your backend and design team.
Do you handle App Store and Google Play submission?
Yes, including store listings, review guidelines, and fixing rejections until the app is approved.
Is Flutter the right choice for my app?
For most products that need iOS and Android, yes: one codebase, native performance, and faster releases. If your app depends heavily on platform-specific features, I'll tell you before we start.
Not sure which fits?
Describe the app and where it's stuck. I'll tell you which option makes sense, even if the answer is a small fix.
