Experience that shaped my design thinking.
Redesigned the entire mobile banking app for Techreo, a fintech serving emerging financial institutions in LATAM.
→ Built and led the UX team from scratch.
→ Delivered a scalable design system and improved user retention.
→ Adapted the app to multiple white-label clients (CAME, Pagaqui, IDEPRO).
Designed a mobile-first financial app (FCIL) for underserved users in Mexico.
→ Led end-to-end UX research and prototyping.
→ Improved task flows for better accessibility and retention.
Mariachi.io is a tech agency that partners with major financial institutions. I worked on UX/UI design for clients like Fincomún, Scotiabank, and Procesar.
→ Led user research: interviews, usability tests, heuristic analysis, and benchmarking.
→ Designed customer journeys, wireframes, and hi-fi prototypes for native apps.
→ Conducted usability testing to validate design decisions before development.
→ Worked closely with developers and stakeholders under agile sprints.
Worked on healthcare dashboards and internal tools for clinicians and staff.
→ Created design systems and validated usability through internal testing.
This app is a branded implementation of the modular banking platform I originally designed for Techreo. I led the full UX/UI design of the base app, creating flexible components and layouts to support multiple clients. For Pagaqui, we customized the interface and removed modules they didn't require, while maintaining usability and brand consistency.
I led the UX/UI design of the onboarding flow for Fincomún’s mobile banking app, “Fácil.” This was a key area of concern due to a high user drop-off rate. Through user research, usability testing, and visual redesign, we significantly improved early user retention.
