Ernesto L.

I design complex digital products—and the systems that make them consistent, scalable and easier to ship. With 15+ years of experience, I help SaaS, fintech, telecommunications and media teams turn complicated workflows and fragmented interfaces into clear, cohesive user experiences. I can lead product design from discovery, user flows and prototyping through polished responsive UI, or strengthen the foundations behind a product through design tokens, component libraries, patterns, documentation, accessibility and governance. I also help teams prepare design systems for AI-assisted and agentic workflows. This includes structuring Figma components, semantic variables, documented patterns and code mappings so people and AI agents can retrieve, understand and apply system intent with clearer context—including through MCP-enabled workflows. Selected outcomes include: • Increasing adoption of a new digital banking journey from 2.52% to 88% • Building 45 components, 25 patterns, 12 templates and 350 design tokens for a telecommunications platform • Helping achieve approximately 75% design-system adoption and 35% faster new-screen design • Creating a responsive white-label streaming platform used across more than six client brands • Redesigning the core experience of a complex B2B product in three months I work closely with product managers, engineers, researchers and content designers, staying involved through handoff, implementation and quality assurance. I’m particularly effective on complex SaaS products, dashboards, operational workflows, responsive platforms and design-system initiatives—especially when a team needs to improve both the customer experience and the way the product is designed and built. If you’re redesigning a product, scaling a design system or preparing your foundations for AI-assisted delivery, I’d be happy to discuss the challenge.
