Product Lead, Developer Ecosystem @ 0x

United States

About

I build products, platforms, and experiences that help developers succeed. Over the past decade, I've worked at the intersection of product, engineering, AI, developer relations, and education—from helping grow the PyTorch ecosystem at Facebook to leading developer platform and agent infrastructure initiatives at 0x. My work centers on the developer journey. I partner closely with engineering, research, product, and GTM teams to understand how developers discover, evaluate, onboard, build, and scale on a platform. By combining direct developer feedback with product analytics, I identify friction points, uncover adoption bottlenecks, and translate insights into product improvements that drive activation, retention, and long-term ecosystem growth. At 0x, I led initiatives spanning developer onboarding, platform adoption, agentic infrastructure, MCP tooling, APIs, CLI workflows, and developer experience products. I also owned key developer-facing surfaces, including the dashboard experience, helping ensure the path from first API call to production deployment was seamless, effective, and delightful. Before 0x, I helped developers learn and build through technical education, documentation, open-source advocacy, and community programs at Facebook AI, PyTorch, and Udacity (Android and Blockchain programs). Throughout my career, I'm most energized when helping others learn, build, and succeed with complex technologies.
