About
Stealth Co-Founder building an AI-native productivity platform for enterprises. We help teams cut through work noise, surface clear, actionable insights, and automate the mundane work that slows organizations down—giving every employee back hours of deep focus and enabling teams to move faster without adding headcount. Previously, I served as an AI Product Lead at Amazon, where I launched Visual ID, a CNN-based facial recognition system built with rigorous fairness standards across ethnicities, genders, skin tones, and abilities. The product scaled to 2M+ daily active users and required deep partnership with Security, Legal, Privacy, and global regulatory teams. I also built Thyme, one of the earliest LLM-powered proactive executive assistants, pioneering anticipatory scheduling and time-management automation. Before Amazon, I was the Product Lead for the first Chromecast remote with Google Assistant, enabling millions of households to use natural voice commands to navigate and stream content. The work demanded cross-functional leadership across hardware, firmware, voice UX, and Assistant integration, helping define a new class of frictionless, voice-driven entertainment experiences. Across all my roles, I’ve focused on building reliable, human-centered AI products at scale—systems that reduce cognitive overhead, integrate cleanly into existing workflows, and deliver measurable business impact.
