User Interface (UI) Chief at LOi

As Head of User Interface Engineering, I directed the visual design strategy and component architecture for LOi's web and mobile platforms. Led the creation, prototyping, and iterative validation of complex interface systems — translating product requirements into pixel-perfect, performance-optimized UI implementations grounded in design system principles and cross-device consistency.

Funciones y Responsabilidades

Funciones principales desempeñadas en esta posición.

  • Author technical design briefs — define problem space, constraints, success metrics, target personas, and technical boundaries before design execution begins
  • Translate product requirements into scalable design systems — atomic design methodology, token-based theming, and component APIs that serve both design and engineering
  • Build high-fidelity interactive prototypes — micro-interactions, state transitions, responsive behavior, and real data integration for realistic user validation
  • Diagnose UX failures through data — analyze funnel drop-offs, heatmaps, session recordings, and A/B test results to design evidence-based solutions
  • Present architecture proposals, product concepts, and design solutions to C-level stakeholders — iterate based on technical and business feedback with versioned decision logs
  • Build and evolve design systems from scratch — token architecture, component libraries (Figma + code), versioning strategies, and cross-platform consistency enforcement
  • Execute the full visual design lifecycle — from moodboards and wireframes through high-fidelity mockups to developer-ready specs with token references and responsive breakpoints
  • Define and enforce design standards — spacing scales, typography systems, color token hierarchies, responsive breakpoint strategies, and interaction pattern libraries
  • Solve complex UX problems through systematic decomposition — reduce cognitive load, eliminate unnecessary states, and design progressive disclosure patterns for power users

Contribuciones y Logros Clave

Iniciativas que lideré, co-lideré, o de las que fui directamente responsable.

  • Established a comprehensive design system with reusable component libraries, design tokens, spacing scales, and typographic hierarchies ensuring visual consistency across all platforms
  • Led the end-to-end UI architecture for the e-commerce platform — from wireframing through production implementation — with ongoing maintenance of the component library and visual regression testing
  • Designed and maintained the mobile application interface, ensuring native-grade interaction patterns and platform-specific design conventions across iOS and Android
