Build platform-level microservices: Design and scale Backend-for-Frontend (BFF) layers and microservices powering maps, search, user dashboards, and preferences across web and mobile platforms.
Elevate developer experience: Empower ~20 feature teams by modernizing monorepo tooling, CI automation, migration pathways, and frontend architectural conventions.
Pioneer AI-first engineering: Integrate advanced AI development tools like Cursor and Claude Code across the engineering lifecycle to optimize workflows and boost technical velocity.
Champion architectural excellence: Architect resilient, decoupled systems leveraging hexagonal architecture, Domain-Driven Design (DDD), event-driven patterns, and micro-frontends.
Mentor and elevate engineering craft: Guide crew members through technical documentation, code reviews, frontend chapter presentations, and biweekly developer sessions.
