Learning from a Bug I Caused

Last week I pushed a code change that broke the login page.

It took two hours before anyone noticed the problem.

My manager called me into a quick meeting.

She asked what happened, and I said, “that one was on me.”

I explained the error and did not make excuses.

Here is what I missed: a small change in the data format.

I assumed the old format would still work fine.

That assumption was wrong and cost us time.

I fixed the bug quickly, but the lesson stayed with me.

To stop it happening again, I will test more carefully.

I will also ask a teammate to review my work.

Owning the mistake made me feel more confident.
