Led six backend engineers, one QA engineer, and one Integration Manager while remaining closely involved in architecture decisions, code reviews, high-risk changes, releases, and production troubleshooting.
Reduced median integration lead time from 10 to 8 business days by standardizing reusable Symfony components and implementation patterns.
Helped reduce incidents by 15% over six months through risk-based reviews of dangerous changes, stronger delivery controls, and improvements to incident-management practices. Established a weekly technical sync with the team to identify, estimate, and assign technical-debt improvements.
Drove an L2 support transformation that reduced developer-bound escalations by 80% within three months: built internal diagnostic tooling, established investigation workflows, and trained the entire L2 team to independently handle complex integration issues previously owned by L3 Engineering.
Partnered with Product, Integration, QA, DevOps, Support, and engineering leads, and joined client escalations to diagnose and resolve integration issues that had remained open for months.
Hired and onboarded five engineers, mentored four specialists through probation, conducted 20+ technical interviews as the primary interviewer, and participated in 20+ additional interviews.

Completed post-incident reviews and postmortems covering root cause, timeline, lessons learned, and preventive action items; contributed approximately 10 operational articles to the SRE Playbook.
Prevented a critical production database incident – identified and stopped unsafe analytical queries targeting the primary production database, moved the workload to a read replica.
