Perguntas frequentes
Do you work on live production systems?
For safety, I recommend bug fixes be tested in staging first. I can assist in both staging and production deployments if access is provided.
What if the bug is bigger than expected?
I’ll let you know upfront if it needs more time than your package includes. We can then adjust the scope or time accordingly.
Will you explain the fix?
Absolutely. I provide a short summary of what caused the bug and how it was fixed so you can learn from it or avoid it in future.
How do you handle sensitive code or data?
I treat your project with full confidentiality. No code is shared or reused, and I’m happy to sign an NDA if needed.
Can you fix bugs in both frontend and backend?
Yes! I work with React/Next.js (Vite) for frontend and Java (Spring Boot, JPA, GraphQL) for backend. I can handle full-stack bug fixes.
What do you need from me to get started?
I’ll need access to your codebase (via GitHub, ZIP, or remote), steps to reproduce the bug, and details on expected behavior. Screenshots or logs help too!
