Profile

Product designer with 5+ years on web and mobile products for mass-market customers. I own the work end to end, from research and flows to high-fidelity design, testing and launch, and I prototype in HTML, CSS and JavaScript. Trained in animation and digital art, I bring motion and visual craft to product work.

Experience

UI Designer at UiX, design team for Banco Azteca

Dec 2024 – present

  • Designed Banco Azteca’s pay-with-a-loan checkout button from proof of concept to production: a mobile web flow where shoppers at partner merchants pay with a loan, through OTP, biometrics, offer and purchase.
  • After launch, diagnosed the funnel with Hotjar session analysis, mystery-shopping purchases in production and a review of 70 merchant checkouts, tracing the largest drop-offs to biometric verification and generic error screens.
  • Redesigned login, OTP and biometric verification (auto-validating OTP, selfie guidance, retry without restarting the flow) and designed distinct error states so each failure cause can be measured.
  • Presented findings as interactive HTML decks with embedded Figma prototypes, aligning product, IT, analytics and commercial partners on a dated action plan.
  • Hold a formal mandate for AI initiatives (20% of my role): designed and led a hands-on Claude workshop for the design team and built its companion web app on Cloudflare Workers.

Customer Experience Manager at Banorte

2020 – 2024

  • Worked across the bank’s innovation lab, project office and customer-experience area: researched emerging technology (digital identity, blockchain payments), presented recommendations to executives and tracked cross-functional projects in risk, branch onboarding and debit cards.

UI/UX Design Consultant at Softtek, assigned to Banorte

2018 – 2020

  • Designed Banorte’s developer portal for its open-banking and regulatory APIs, including the ATM-locator and merchant-acquiring APIs, as responsive layouts for desktop and mobile.

UI/UX Designer at Ryndem Studios

2016 – 2018

  • Designed management software for lab reagents (Proquifa) and restaurant wine cellars (WineAdvisor) and the Holland Animal Health website; moved the studio to Sketch and Zeplin.
