Timeline
I lead Toyota’s next-generation connected-vehicle platforms, owning end-to-end delivery across Toyota Japan, LG, Denso, and Continental for DCM software spanning multiple vehicle generations. Operating at the intersection of hardware, embedded systems, cloud services, and regional launch governance, I focused on launch readiness, defect prevention, and scalable validation—driving a ~40% reduction in pre-production defect leakage and materially improving global launch predictability. I established the Environment Readiness Check (ERC) framework, accelerated validation through shift-left automation, and built telemetry dashboards linking backend, DCM, and vehicle-health signals to enable early anomaly detection and faster executive decision-making.
At Amazon, I led large-scale technical programs across Buy with Prime, applied AI/ML, and internal platform enablement, operating across 18+ globally distributed engineering, product, and ML teams. My role centered on translating ambiguous business goals into executable roadmaps, aligning portfolio priorities, and driving executive governance across multi-year initiatives. Key outcomes included a ~25% conversion uplift through Buy with Prime on Shopify, a ~70% reduction in manual reviews via ML-driven fraud and abuse mitigation, and a ~40% reduction in developer onboarding time through an enterprise-grade RAG Knowledge Assistant. Across programs, I balanced customer impact, operational rigor, and long-term platform scalability while maintaining compliance in highly regulated domains.
At Columbia Sportswear, I led the global rollout of Salesforce Commerce Cloud across 20+ countries, establishing scalable delivery governance and improving reliability across distributed teams. The program strengthened executive visibility, reduced defect cycles, and accelerated global market launches.
At Intuit, I supported the global expansion of QuickBooks Online, focusing on platform scalability, cloud migration, and regulatory readiness. I played a key role in Agile transformation efforts that increased release velocity while maintaining compliance across regulated environments.
At American Honda Motors, I led the delivery of next‑generation connected‑vehicle platforms for Honda’s PHEV and EV programs, spanning mobile, web, and telematics systems. Working across global engineering teams in the U.S., Japan, and offshore centers, I strengthened governance, improved delivery efficiency by ~20%, and advanced Honda’s early connected‑services capabilities through disciplined program leadership and cross‑functional alignment.
In my early career, I delivered safety-critical aerospace and industrial automation software across aerospace, rail, and HVAC domains, gradually transitioning into technical leadership roles through consistent delivery excellence and cross-functional ownership.
