FAQ
Should I contact you before placing an order?
Yes. Please contact me before ordering and describe the issue. I will review the available information and confirm the appropriate package based on the complexity and investigation required.
What information do you need to investigate the bug?
Please provide the error message, logs, expected behavior, actual behavior, reproduction steps, technology versions and access to the source code or a minimal reproducible example. Clear setup instructions are also required.
How do you determine which package is appropriate?
The package depends on the complexity of the investigation, the number of files and application layers involved, and the testing required. A single visible error may still require an advanced package if its cause is complex.
Can you add a new feature instead of fixing a bug?
Yes, I can also develop small features, REST endpoints, database changes and API integrations. Please contact me first so I can review the requirements and send you a custom offer.
Do you work with both Java and Kotlin Spring Boot projects?
Yes. I work with Java and Kotlin applications using Spring Boot, Hibernate, JPA, PostgreSQL, REST APIs, Maven and Gradle.
Can you fix an urgent production issue?
This Gig is not intended for immediate production emergencies or real-time support. I work asynchronously and need enough time to investigate, implement and test the solution properly.
Is my source code kept confidential?
Yes. Your source code, credentials and business information will remain confidential and will only be used to complete the agreed work. Please provide temporary or restricted access whenever possible.
