He pairs hands-on development with mentoring and code review, and has improved developer productivity through tooling and integration work such as KeyCloak reorganization and EDM integrations. Comfortable debugging production incidents end-to-end, he emphasizes tests, metrics and postmortems to eliminate root causes rather than papering over symptoms.
