Alexa Mobile App

https://alexa.amazon.com
Within the Alexa app, the redesigned Skills & Games section allows customers to find and use new features that are both built-in or created by third-party developers. The content presented in this section of the app is personalized for each user. As the senior front-end engineer in the organization, I was tasked with the system design and implementation for the client-side implementation and service integration. I coordinated with UX designers, project managers, and other engineers to define the scope of work and timeline for project deliverables. I also worked with back-end engineers to update API definitions and consulted on technical system design documents. This project included four new back-end services, several new user interfaces, and numerous new reusable components, all built within the constraints of the existing Alexa app ecosystem.

Oakley.com

https://www.oakley.com
I led the front-end development effort in an entire site and platform overhaul, from a basic Ruby stack to the omnichannel commerce platform Hybris. This involved the management of two other engineers, defining project scope and timelines for deliverables, architecting the modular framework for reusable front-end components, and defining the pattern for integrating that front-end with the Spring-based service layer.
