Tell us about your biggest fail.

One of the biggest fails happened when I accidentally deleted an important part of the data in production due to a migration script error. This occurred because of insufficient testing and lack of backups at the time.

After that, I implemented several important practices:

• Mandatory testing of migrations in the staging environment.
• Creating backups before making changes to the database.
• Implementing code review processes for critical changes.

This experience taught me attentiveness and the importance of quality control processes, which significantly reduced the risks of similar errors in the future.
