FAQ
Which platforms and frameworks do you support?
I specialize in debugging and optimizing Flutter, React Native, and Ionic apps, as well as native iOS (Swift/Objective-C) and Android (Kotlin/Java) projects.
How does AI-enhanced debugging help?
Using tools like Cursor and Roocode, I can detect errors faster and more accurately—up to 3× quicker debugging than manual methods—plus predictive bug detection before deployment.
What do you need from me to get started?
Please share your app’s code (e.g., GitHub repo or archive), a bug report or issue description, and any error logs or crash reports. That allows me to scope accurately and start efficiently.
Can I get fast delivery if it's urgent?
Yes! The Basic package delivers in 2 days. For critical issues requiring same-day attention, please message me and we’ll expedite as needed (extra fee may apply).
What if I’m not satisfied with the results?
Your satisfaction is guaranteed. Each package includes revisions (1–3 depending on tier), and if you're not happy, we’ll work until it's right—or refund as per Fiverr’s policy.
