When I broke production, and it almost broke me
summary
A React change to a core payments service is rolled out without a teammate review, forgot to ask teammate, and promptly causes customers to be unable to pay; investigations show the deployment path and a frontend validation edge case combine to drop a few million krona in transactions. A manager insists on a blameless investigation, documents the faulty deploy script and missing tests, runs training and a public postmortem, and the engineer converts the failure into shared process improvements and mental health recovery.
