Lacerda

I am a and based in Montreal, Canada.

I build thoughtful digital products with a deep focus on interface craft, accessibility, performance, and design systems that scale.

6+ years at Shopify building the Checkout Polaris design system and first-party theme architecture, and the user experience details that make checkout feel effortless.

My development workflow is AI-native: I orchestrate multiple AI agents from PRD to code and review — moving faster without lowering the bar.
