FAQ
What kinds of API issues can you fix?
I resolve authentication failures, broken endpoints, webhook problems, timeout errors, validation issues, incorrect responses, payment API failures, database-related errors, and communication problems between services.
Can you work with an existing project instead of building from scratch?
Yes. Most projects involve existing applications. I can review your current backend, understand the architecture, identify the root cause of the issue, and implement the necessary fixes without disrupting unrelated functionality.
Which backend technologies do you support?
I primarily work with Laravel, PHP, Node.js, Express.js, Java Spring Boot, MySQL, PostgreSQL, Redis, Docker, REST APIs, GraphQL, and modern backend architectures.
Can you integrate third-party services?
Absolutely. I integrate payment gateways, authentication providers, CRMs, email services, SMS platforms, cloud storage, shipping APIs, AI services, and many other external systems.
Do you fix production issues?
Yes. I can troubleshoot production environments carefully while minimizing downtime. I also investigate server logs, application logs, and deployment-related issues when access is available.
Will you explain what caused the problem?
Yes. I believe clients should understand what went wrong. Along with the fix, I explain the root cause and the changes made so future maintenance becomes easier.
Can you improve API performance as well?
Yes. Besides fixing bugs, I optimize database queries, reduce response times, improve caching strategies, eliminate unnecessary API calls, and enhance overall backend efficiency.
What should I do before placing an order?
Send a message with a brief description of the issue, your technology stack, error messages (if available), and your expected outcome. This helps determine the best approach before work begins.
