• Hi! I'm Victor, a developer and interaction designer. I work where design and code overlap.

  • I build ideas from the ground up. From wireframes to polished mockups to functional code.

  • LLM Party is my current side project.

  • Inspired by The Cyberiad and Make It So.

  • Let's connect!

Work Experience

  • Product Designer & Mobile Engineer (contract)

    Consumer mixed-reality startup

    Sole design and mobile engineer on an early-stage consumer product. Owned the React Native / Expo app end to end: architecture, implementation, and interaction design. Built the Supabase backend and Deno edge functions, contributed to the Unity 3D client, and defined the product's design language in Figma. Shipped to TestFlight with external testers; the company wound down in 2026.
  • Head of Design

    CredCore

    Led design at an AI fintech analyzing debt and credit documents. 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.
