At Vellum, I simplified an overgrown AI workflow product and designed a chat-based builder that lets people create workflows by describing them. I also defined a personal AI assistant from zero, from competitor research and its core feature set to a new visual identity and Figma design system.

I contributed production code with Claude Code, rebuilding most live UI components and shipping new features. That cut design-fix turnaround from about a week to a day.

At Alma AI (Almaca Inc.), I built a design system and designed major features including invoicing, advanced reporting, integrations and an overview dashboard. I partnered with leadership on product strategy, contributing to 100% month-over-month revenue growth and $1.5M ARR within 6 months.

At CloudKitchens, I designed the Courier app and helped pilot it across 2 continents through to US launch. I also contributed to Facility Hub and delivery analytics dashboards; across my work, I’ve designed products in AI, healthcare, logistics and B2B SaaS.
