July 1, 2025 - Present

Build and maintain features across a microservices architecture spanning Elixir/Phoenix, Node.js/TypeScript services, NestJS, and React/Next.js applications. Work across Focus Dashboard, Admin 2.0, authentication, and analytics tooling. Integrate internal AI systems into engineering workflows, including multi-agent orchestration with retrieval-augmented memory and remote session control. Designed and built Admin 2.0 “Create Member API” (NestJS + TypeORM) with transactional multi-table inserts and validation that collects all errors rather than failing fast. Built a web push notification system (VAPID) across Elixir/Phoenix and React with per-member-coach throttling. Rolled out a cross-service error code system to improve observability and debugging speed. Optimized PostgreSQL queries using EXPLAIN ANALYZE and composite indexing, cutting coach dashboard query execution time by ~70–80%.
