With experience building and scaling design systems at companies like Splunk, DocuSign, Schlumberger, and Supercoder, I’ve learned that good design isn’t just about polished Figma files—it’s about how well it translates into real, reliable product experiences. I focus on bridging design and engineering through clear system architecture, robust component thinking, and AI-assisted workflows. I work more like a design system engineer than a traditional designer: defining component structures, tightening the relationship between tokens, UI patterns, and code, and using tools like Claude and Gemini to generate and refine implementation-ready UI, documentation, and even draft pull requests. This lets teams move faster while keeping interfaces consistent, scalable, and maintainable. At Supercoder, I joined a fragmented set of three overlapping products and helped unify them into a cohesive AI hiring platform by mapping end-to-end flows, clarifying the “north star,” and organizing the system around shared patterns. I’m at my best in ambiguous environments where structure, hierarchy, and clarity need to be created from scratch. My background in acting, culinary arts, and finance also gives me a broad, human lens on behavior and decision-making, which I bring into UX thinking to keep complex systems intuitive and empathetic. * I’ve opened some slots for 1:1 chats to discuss my work, future collaborations, or to simply connect. ☕️ Grab a time here — https://calendar.app.google/BS2YFrxtbG1hJjKH7
