Amazon is guided by four principles: customer obsession rather than competitor focus, passion for invention, commitment to operational excellence, and long-term thinking. We are driven by the excitement of building technologies, inventing products, and providing services that change lives. We embrace new ways of doing things, make decisions quickly, and are not afraid to fail. We have the scope and capabilities of a large company, and the spirit and heart of a small one.\n\nTogether, Amazonians research and develop new technologies from Amazon Web Services to Alexa on behalf of our customers: shoppers, sellers, content creators, and developers around the world.\n\nOur mission is to be Earth's most customer-centric company. Our actions, goals, projects, programs, and inventions begin and end with the customer top of mind.\n\nYou'll also hear us say that at Amazon, it's always "Day 1." What do we mean? That our approach remains the same as it was on Amazon's very first day - to make smart, fast decisions, stay nimble, invent, and focus on delighting our customers.

Technical Lead on several body camera subsystems. Highlights: - Led a small team to develop a CAD/location-based activation system for body cameras, enabling dispatch to remotely activate cameras either through user input or automatically when a camera enters a geofenced area. Preserved camera battery-run-time while also allowing the camera to always remain connected to cloud services. - Connectivity Lead; developed a system to adapt and manage WiFi/LTE interoperability for a variety of connectivity at-the-edge use-cases. Lead triage for customer issues around connectivity. - Owned evidence ingestion subsystems, overseeing the entire pipeline from the moment evidence is captured by the camera to its successful upload. Made improvements to the on-device evidence management and refactored the client->cloud interface to improve observability and error handling. Lead triage for customer issues. - Owned initiative to create an observability platform for body cameras, to improve time-to-detect of issues during release waves.
