Ux Ui Designer

 
Product Designer with 6+ years of experience leading end-to-end product strategy and UX delivery across nonprofit SaaS, EdTech, Web3 gaming, and consumer platforms. Specialized in information architecture, design systems, and complex workflow optimization, partnering with engineering and leadership to ship scalable, metrics-driven products.

As a UI Designer at Tazki, I designed and scaled a Figma design system with 1,500+ components and variants across web and mobile. I defined system architecture including naming conventions, design tokens, spacing, color variables, typography, and interaction rules. I standardized UI states and accessibility using brand guidelines and WCAG principles to ensure consistency and contrast compliance. I collaborated closely with designers and developers to align components with implementation constraints, reducing design to development friction, and built a Notion component inventory to document system usage.

As a UX/UI Designer at Skillcap, I delivered 12+ responsive desktop and mobile screens across dashboards, profiles, inventory, marketplace, and housing views, translating complex roguelite and player-run data into scalable interfaces. I designed gamified dashboards visualizing 10+ per-run metrics to support progression and engagement. I defined end-to-end UX flows for a Web3 NFT marketplace, mapping a five-step blockchain withdrawal process with clear system feedback, error handling, and transaction state visibility, and established information architecture and navigation models.

As a Product Designer at Fundación ConTrabajo, I owned end-to-end product strategy and delivery for a custom SaaS evaluation and case management platform. I translated cross-departmental requirements into technical specifications and acted as the primary product decision maker for the CFO and six departments. I led Agile delivery with two developers, managing weekly sprints and 500+ tasks over 13 months. I architected a scalable system supporting multiple programs, 150+ participant profiles, 16 evaluation types, and 8 status progressions. I reduced evaluation and reporting time by 70% and increased monthly evaluation throughput by over 70%.
