• Exceptional analytical skills with a proven ability to dissect complex, distributed system issues, determine root causes, and engineer sustainable technical solutions.
• Strong proficiency in inspecting application logs, tracing network requests, evaluating APM metrics, and analyzing heap and thread dumps to isolate defects.
• Proven ability to efficiently prioritize active high-severity cases and lead critical production incidents to swift resolution.
