Production incident resolution
Problem
A production incident requires restoring operation without widening the impact or turning an urgent fix into a difficult-to-reverse change.
Analysis
I review the scope, symptoms, recent changes, and available information. I reproduce the behavior when possible and do not treat a cause as confirmed before checking it.
Solution
I apply a small, reversible fix along the affected flow. At MP Sistemas, the process can continue through build, deployment, and remote support when needed.
Validation
I check the original flow and nearby scenarios, review side effects, and record what was learned so the next incident does not start from zero.
Result or learning
Learning: restoring service and understanding the cause are related tasks, but they are best handled in that order.
