FAQ
What information or access do I need to provide before you start?
To get started, please provide a clear description of the bug, any relevant error logs or stack traces, and access to the codebase(e.g., via GitHub/GitLab access, a ZIP archive, or relevant project files). For database or deployment issues, sharing your sanitized application.yml/properties or Docker
How do we handle project privacy and sensitive data?
Confidentiality is top priority. Please do not share production credentials, API keys, or real user data. I recommend replacing sensitive values with mock placeholders in configuration files prior to sending.
Can you help fix build errors related to Java or Spring Boot version upgrades?
Yes! I can help resolve build failures, broken dependencies, and deprecated library methods caused by upgrading Java versions (e.g., updating to Java 17 or Java 21) or upgrading Spring Boot and Spring Security releases.
What if the bug requires more time or turns out to be a larger issue?
If initial diagnostic work reveals deeper structural issues or additional feature requirements beyond the agreed order scope, I will pause work immediately and provide a detailed diagnostic report along with a custom offer before proceeding.
Do you test the fix before delivering the final order?
Absolutely. Every fix is thoroughly built, verified locally, and tested against your specified use cases or unit tests to ensure no regression issues are introduced before delivery.
