Career

Grappeggia's career is marked by a progression through engineering and product leadership roles at major technology companies, with a focus on developer tools and cloud infrastructure.

Early Career

Grappeggia's early career included roles at Amadeus and McKinsey. ^[1]​

Appurify

Before his tenure at Google, Grappeggia was the Product Lead at Appurify, a company focused on providing mobile test automation services on real devices. Under his product leadership, the company developed technology that ultimately led to its acquisition by Google. Following the acquisition, Appurify's technology was rebranded and integrated into Google's developer platform as Firebase Test Lab. ^[1]​

Google

As a Group Product Manager at Google, Grappeggia was a key figure in the development of several high-profile developer products. His achievements include contributions to Gemini Code Assist, various Firebase products, and leading product management for Google Cloud Workstations and Cloud Shell. ^[1]​

In his capacity as the product manager for Cloud Workstations, he positioned it as a primary, managed development environment for daily tasks, providing secure, customizable, and pre-configured settings through container-based templates. This design allows integration with an organization's existing security infrastructure, such as Virtual Private Clouds (VPCs) and Identity and Access Management (IAM). In contrast, he described Cloud Shell as a free, supplementary tool intended for short-term tasks, onboarding new developers, rapid prototyping, and product evaluation. ^[1]​

During a podcast appearance in December 2022, Grappeggia outlined a strategic vision for Cloud Workstations that included achieving general availability, integrating a broader array of developer tools, expanding support for different developer archetypes like mobile and game developers, and deepening security integrations within Google's Software Delivery Shield suite. ^[1]​
