Perguntas frequentes
What do I need to provide for you to start?
Please message me before ordering! To help me solve your problem fast, please provide: A clear description of the bug (What you expect vs. what is happening) Screenshots or a short video of the bug. The relevant code. The best way is to add me as a collaborator to your private GitHub/GitLab repo
What if my bug is more complex than your Basic package?
This is why it's so important to contact me first. If you send me the details, I will analyze the problem and send you a fair Custom Offer with an exact price and delivery time. You will always know the full cost before you order.
Why are your prices for this 'bug fix' gig so low?
As a professional software engineer, my goal is to build a strong reputation here on Fiverr. You are getting my full expertise (including my experience at SLT Mobitel) at a special introductory price. My priority is to earn your 5-star review with excellent, fast work.
My bug might be in the backend (API / PHP), not the Flutter app. Can you fix that?
Yes! This is my specialty. I am a full-stack developer with professional experience in both Flutter and PHP/MySQL. If I find the bug is in your API and not the app, I can fix that too. Just let me know when you message me.
Can you add a new feature instead of just fixing a bug?
Absolutely. My Standard package covers a small feature (like a new button, function, or simple screen). If you need a larger feature, please check out my Full-Stack App Development gig, or message me for a custom quote.
How do I know my code is secure with you?
Your code and project idea are 100% confidential. I am an Associate Software Engineer and follow professional ethics. I will only use your code to fix the bug you hired me for, and I will delete all local files after the order is completed and approved.
Can you fix Gradle build errors or iOS Podfile issues?
Yes! I specialize in resolving complex build errors, Gradle version conflicts, and iOS Podfile issues to get your app running again.
Do you fix backend API or PHP/MySQL issues connected to Flutter?
Absolutely. As a Full-Stack developer, I can debug your PHP APIs, MySQL database queries, and their integration with your Flutter app.
Will you rewrite my code if it is messy?
My primary goal is to fix the bug. However, I always write clean, maintainable code. If a refactor is needed for stability, I will let you know.
