Work Experience

  • Product Designer & Mobile Engineer (contract)

    Physical AI startup

    Early-stage company exploring physical AI, with a consumer mixed-reality app as its first test case. Owned the React Native / Expo app end to end, from the design language in Figma to architecture and implementation, and built the Supabase backend with its Deno edge functions. Contributed to the Unity 3D client. Shipped regular TestFlight builds to external testers.
  • Head of Design

    CredCore

    Led design at an AI fintech analyzing debt and credit documents, including its agentic workflows for credit analysis. Grew the team 2 to 6 as the company scaled 8 to 50 (Series A). Owned a platform redesign, prototyped flows in React, built the Figma + Storybook design system, and led a rebrand. Reported to the founder as the design, product and engineering interface.
  • Lead UX Developer

    Field Inc, Berlin

    Pharmaceutical supply-chain platform serving 100+ healthcare providers in Nigeria and Kenya. Joined writing React and D3, then took over design of workflows and data visualizations for drivers, warehouse staff, and pharmacists; eventually owned the Figma design system. Shipped a forecasting dashboard for pre-ordering vaccines and antimalarials ahead of seasonal outbreaks. The mobile app was built for low-connectivity rural environments.
  • Interaction Designer

    Metadrop, Spain

    Designed and prototyped for clients including UNICEF, Save the Children, and Telefonica. Built embeddable visualizations and custom GUIs in Drupal. Shipped Dr. Robert, an early chatbot replacing complex pharmaceutical-database UIs. Doctors could look up disease-medicine links, generics, and active ingredients via chat.
  • R&D Engineer & Mobile Maker Space Director

    BQ, Spain

    Founded and directed CIRCOLAB, a BQ-funded mobile maker-space initiative: led a team of six on a nationwide Spain tour, running 40+ workshops with original curriculum and reaching 2000+ participants. As a member of the robotics lab, also helped prototype Bluetooth firmware and the block-based programming app for Zowi, BQ's flagship educational robot.
  • Software and Hardware Prototyping

    Motorola ATAP - Google ATAP

    Joined the MakeWithMoto tour as an on-site prototyper, a mobile maker space visiting top US universities (MIT, Berkeley, CalTech, Carnegie Mellon, Texas A&M, among others) and industry partners. The program was Motorola ATAP's design research for what would become Project Ara, the modular smartphone; we ran hands-on prototyping workshops to validate modular-hardware concepts.
  • STEAM Education Designer / Researcher

    The Patching Zone, Rotterdam, The Netherlands

    Co-designed and co-taught a year-long STEAM curriculum for two cohorts of vocational students (~30 total, ages 13 to 17), funded by the Mondriaan Fund. Coursework spanned Processing, interaction design, mixed reality, game design, and video creation. Cohorts built a location-based mixed-reality game played through audio while walking the streets.
  • R&D Engineer

    Deimos Space, Madrid, Spain

    Worked on SemSorGrid4Env, an EU collaboration between industry partners and universities building wireless sensor networks for forest-fire and flood detection. Contributed embedded C prototypes; the project produced research papers and a field pilot that deployed after my time.
