Do you build both Android and iOS apps using Flutter?
Yes! I use Flutter to build cross-platform apps that work seamlessly on both Android and iOS devices from a single codebase.
Can you fix bugs in my existing Flutter app?
Absolutely. Share your codebase and a short description of the issue, and I’ll investigate and provide a fix cleanly and efficiently.
What do you need to get started?
I typically need: A brief about your app or issue Design files (if available) Access to your code (for bug fixes or enhancements) Any specific feature list or integrations you'd like
Do you offer post-delivery support?
Yes! I offer limited support for small fixes after delivery. Long-term maintenance or major updates can be arranged separately — just message me.
