FAQ
1. Should I contact you before placing an order?
For a small and clearly defined bug, you can order the Basic package directly. For complex bugs, new features, multiple issues, or an unclear scope, please message me first so I can review the requirements and recommend the correct package.
2. What technologies do you work with?
My main backend technologies include: PHP, Laravel, Node.js, REST APIs, MySQL, PostgreSQL, Redis, queues, scheduled jobs, webhooks, and third-party API integrations.
3. Can you work on an existing project?
Yes. This Gig is specifically suitable for existing applications where you need a bug fixed, functionality improved, or a new backend feature added.
4. Can you build a complete application?
Yes, depending on the requirements. Complete applications are not covered by the predefined packages because the scope can vary significantly. Send me your requirements and I can provide a custom offer.
5. Can you fix database performance issues?
Yes. I can investigate slow queries, database design issues, Eloquent queries, N+1 problems, indexes, and other MySQL/PostgreSQL performance issues. Larger performance audits may require a custom offer.
6. Can you develop REST APIs?
Yes. I can create, debug, modify, or integrate REST APIs and backend endpoints in Laravel or Node.js applications.
7. Can you work with third-party APIs and webhooks?
Yes. I can integrate third-party APIs, debug existing integrations, implement webhook handlers, and troubleshoot failed API communication.
8. Will you rewrite my entire project to fix one bug?
No. My first approach is to identify the root cause and make the smallest clean change necessary without unnecessarily affecting the rest of your application. If architectural changes are required, I will explain them before proceeding.
9. What if you discover that the issue is larger than expected?
I will explain what I find and what additional work is required. Work outside the agreed scope can be handled through an additional or custom offer.
10. Do you provide support after delivery?
Yes. If something directly related to the delivered fix does not work as agreed, I will review it within the revision scope. New features or unrelated problems are considered separate work.
