I set multi-year design direction with stakeholders and research, then build the systems and prototypes a team needs to ship against it. At Render I own design for the networking and platform scaling surfaces. At Auth0 I was design lead for security products tied to $20M+ in ARR growth and retention, and helped scale the design organization through hiring, onboarding, and mentorship. ## Experience ### Render Senior Product Designer 2025 – Present - Established a code-native, agent-assisted prototyping workflow so designers and product managers can deploy frontend experiments directly on Render. - Reduced the time to connect with external infrastructure from a multi-day manual support process to self-serve, doubling adoption in three months to carry roughly 30% of inbound platform traffic at a fifth the cost of public egress. - Expanded bandwidth observability to support new traffic types, exposing roughly 60% of outbound traffic the platform had never shown users, which let us reprice network bandwidth and significantly improve networking margins. ### Auth0 (acquired by Okta) Staff Product Designer 2024 – 2025 - Design lead for the Customer Identity Cloud security platform, setting multi-year direction with stakeholders through user research, competitive analysis, and security domain expertise. - Scaled the security design function without a formal reporting line: ran hiring loops, onboarded senior designers and interns, and owned project planning across the group. - Mentored senior ICs and rebuilt onboarding materials, shortening the ramp for designers new to identity and security. ### Auth0 (acquired by Okta) Senior Product Designer 2021 – 2024 - Led and shipped designs that expanded the security product portfolio, contributing to $5M+ ARR growth over three years. - Designed the launch experience for passkey authentication, which influenced $15M+ ARR in retention deals and exceeded its adoption target by 361% in the first quarter after release. - Pitched and shipped a new security observability platform to meet enterprise demand, creating the foundation for new capabilities and upgrade paths across the security portfolio. - Drove design system operations to 100% design and code parity for web components, reached full documentation coverage within a year, and introduced a hybrid contribution model for new components and patterns. ### McAfee Product Designer 2019 – 2021 - Established the Pegasus Design System with a cross-functional team of five, and defined the visual identity for McAfee Personal Protection, the flagship consumer security product. - Owned the end-to-end service diagram for the Personal Protection user journey, and built training material that raised throughput for the design and research functions. ### McAfee UX / Visual Design Intern 2018 – 2019 - Concepts for McAfee Gamer Security were selected as the final product design at launch. ## Education ### University of Waterloo Bachelor of Global Business and Digital Arts 2015 – 2019
