root cause, not symptom

Bug fixing
in
production.

I find the root cause of a bug — not just the symptom: I reproduce the problem, eliminate it, and close it so it doesn't come back — whether it's a 500 error, a logic failure, or an integration crash.

handled first.

A bug in production means lost leads and lost user trust. I approach bug fixing systematically: first I reproduce the problem, find the root cause, fix it, and verify the fix didn't affect adjacent functionality.

01 / How I Fix Bugs

How I fix bugs

Diagnosis

I reproduce the bug, study logs and traces, find the root cause — not just the external symptom.

Fix

I fix the problem with minimal invasiveness and verify that adjacent logic wasn't affected.

Critical incidents

I help with production outages — rapid engagement and priority response.

Prevention

Where appropriate, I add a test or validation so the same error doesn't recur.

FAQ

Частые вопросы

How quickly do you respond to a critical bug?
Critical production incidents are handled with priority. Exact response time depends on the engagement format — with monthly retainer support it's agreed upfront.
