BEFORE ORDERING
Message me with your app platform, steps to reproduce the issue, relevant logs and the expected result. I will review the scope and confirm the price and timeline. Complex investigations or additional features may need a custom offer.

FAQ
Do you work on both iOS and Android apps?
Yes. I have delivered iOS and Android products, including custom keyboards. My deepest expertise is native iOS with Swift, Objective-C, UIKit and SwiftUI. Send your platform, framework and issue details so I can confirm the scope before you order.
Should I contact you before placing an order?
Yes, please message me before ordering. This helps me understand your app, confirm feasibility, and provide the best and most accurate solution. 👉 Free consultation included.
Can you fix app crashes and App Store / Play Store issues?
Yes. I diagnose crashes and review the exact rejection notice, then quote the necessary code changes and resubmission support. Store approval is decided by Apple or Google and cannot be guaranteed.
Do you provide support after delivery?
Yes. Support covers reproducible issues caused by the delivered changes, within the support period agreed before ordering. Revisions stay within the original scope. New features, unrelated bugs and third-party changes require a separate quote.
Can you update old or legacy code?
Yes. I can refactor outdated code, migrate old implementations, improve performance, and make your app stable and scalable.
Will you sign an NDA if required?
Yes, I respect client privacy and can sign an NDA if needed.
What if my issue is bigger than the selected package?
No worries 😊 If the issue requires more effort, I’ll let you know before starting and suggest the best package or a custom offer.
My app was built with AI (Cursor, Lovable, Bolt, ChatGPT) and does not work. Can you fix it?
I can review an existing mobile project for build errors, crashes and missing integrations. Send the framework, issue details and relevant code so I can confirm feasibility and quote the work. A web-to-native rebuild may require a separate scope; store approval is not guaranteed.
