•Owned and operated backend services integrating 7+ external systems with inconsistent APIs, auth mechanisms, and data quality, powering a health plan platform serving 800k+ members.
•Designed provider search and ranking systems with geospatial filtering, attribute normalization, and sponsor-specific constraints, balancing relevance with latency and correctness.
•Built clinical benefits and cost transparency pipelines integrating external pricing services; normalized unreliable third-party data and designed graceful degradation to preserve core member flows under partial vendor failures.
•Architected a CMS content migration (Hygraph) including an in-memory locale cache with startup validation — decoupling content from deployments and preventing silent production failures.
•Acted as tech lead during senior engineer absence on a primary care network launch: reviewed code, filled implementation gaps, coordinated with external vendors, and drove production deployment on deadline.
•Drove adoption of a post-production validation framework, endorsed by leadership as the team standard; owned change-board-approved production releases.
•Led incident response for a production outage — isolated root cause to expired vendor credentials, escalated with structured context, and proactively built team knowledge to prevent recurrence.
•Mentored contractors and junior engineers through backend service knowledge-transfer sessions and first-PR pairing; deliberately reduced single points of failure on the team.
•Presented to engineering leadership on integrating AI tooling into backend development workflows in a healthcare context; achieved 40–50% faster development cycles and drove team-wide adoption.
•Enabled multi-tenant feature rollouts using feature flags, supporting sponsor-specific logic, safe experimentation, and fast production rollback.
