I will fix, update, and take over your existing flutter app
Hoang Nguyen
Hi, I'm Hoang. I've spent 10+ years building software — from React-based
web products to native mobile apps for e-commerce businesses across
multiple industries.
What sets my work apart isn't templat...
Over deze dienst
Your Flutter app is a business asset and right now it may be quietly
dying. Google and Apple raise their SDK requirements every year: apps that
don't update get warnings, then get removed. Flutter itself moves fast
an app untouched for 18 months often won't even build anymore. And if your
original developer disappeared, you're stuck holding a codebase nobody
understands.
WHAT THIS GIG COVERS:
- Bug fixes and crash diagnosis
- Upgrade to the latest stable Flutter + dependency updates
- Google Play / App Store compliance (target SDK, policy changes)
- Taking over abandoned codebases: audit, fix backlog, document, maintain
WHY TRUST A STRANGER WITH YOUR PRODUCTION APP?
My own apps are live on the App Store & Google Play I've maintained
them through every SDK cycle, for years
10+ years of engineering. I read code before I touch it: health check
first, honest report, then only the fixes you approve
I don't break production. That's the whole job.
After delivery, most clients keep me on a monthly care plan so you never
have to think about store policy emails again.
Send me your app's store link + what's wrong. I'll respond within hours.

Veelgestelde vragen
My developer disappeared and I only have the APK — can you help?
I need the source code (Git repo or zip). An APK alone can't be maintained. If the source is truly lost, I'll give you an honest rebuild estimate — sometimes cheaper than you fear.
What exactly is in the health check?
Build test on current toolchain, dependency audit (abandoned packages), store compliance status, a read of code quality, and a prioritized fix list with per-item pricing. You'll know exactly what shape your app is in.
Google sent a warning / removed my app — can you fix it?
Yes, this is my bread and butter. It's usually the annual target SDK requirement or a policy form. Standard covers the update + compliant rebuild + resubmission support.
Can you add new features, not just fix?
Yes. After takeover I quote features individually, and the monthly care plan includes small improvements. Big features get a custom offer.
Will you break my live app?
Health check first, changes in a separate branch, test build for your approval before anything touches production. My own apps have survived years of my maintenance — yours will too.
What does the monthly care plan cost?
Depends on app complexity — typically from $99/month for compliance + fixes. I'll include a quote with your delivery, no obligation.
