Summary
Acting as a trusted advisor to top leadership, I lead and grow platform teams to drive engineering excellence, developer experience, and system testability. I take full technical ownership of projects—from concept to delivery—with deep hands-on expertise in building custom UI controls, designing communication protocols, and implementing delegate interfaces.
I collaborate closely with product, web, and backend teams to shape and deliver creative features, while incorporating feedback from UX, architecture, and quality teams.
I bring practical experience in A/B testing, feature configurations, and a strong technical foundation across MQTT, CoAP, SQL, HTML, JS, Apple HomeKit, SceneKit, Jenkins, and IoT components like Bluetooth HM10 and ESP32.
My work has powered large-scale digital transformations for brands like McDonald’s, Warner Bros. World, Ferrari World, and YAS WaterWorld. I currently hold two patents in process at Walmart Global Tech.
