summary: >
  Tomás is a full-stack engineer with five years of experience
  delivering customer-facing web applications. He moves comfortably
  across the stack — TypeScript backends, React frontends, and the
  build / observability glue around them — and enjoys working
  closely with designers to ship features that feel right.

experiences:
  - company: Vivanto Health
    role: Full-stack Engineer
    period: "Jan 2024 - present"
    description: >
      Context: Vivanto is a B2C tele-health platform serving
      150k monthly active patients across France and Belgium,
      with a strong emphasis on accessibility and clinical UX.

      Responsibilities: full-stack IC on the patient-facing
      product team (8 engineers + 2 designers). Pairs weekly
      with the design lead to refine flows before
      implementation; second-line support on production
      incidents.

      Key contributions: rebuilt the appointment-booking flow
      with optimistic UI, lifting completion rate from 71% to
      88%; introduced React Server Components for the
      content-heavy education hub, cutting Largest Contentful
      Paint from 3.4s to 1.1s; shipped the GraphQL persisted-
      query pipeline that lets the mobile app cut data usage
      by 40%.

      Source of pride: the booking-flow rework was the first
      project where engineering, design and customer-success
      shipped a shared metric improvement together.

  - company: Atelier Numérique
    role: Frontend Engineer
    period: "Jul 2021 - Dec 2023"
    description: >
      Context: a Paris-based digital agency building bespoke
      web experiences for cultural institutions (museums,
      theatres, public archives).

      Responsibilities: frontend IC across 4-6 client projects
      in parallel, sole owner of the build and deployment for
      the smaller ones; close contact with project managers
      and clients on scope and trade-offs.

      Key contributions: built the new public catalogue for
      a national archive (1M+ records, faceted search, fully
      keyboard-navigable); shipped a React Native companion
      app for a museum's audio-guide programme; consolidated
      the studio's 4 separate webpack configs into a single
      shared Vite preset.

      Source of pride: the museum companion app was used by
      120k visitors in its first season and got featured in
      a national newspaper's culture section.

  - company: Studio Vega
    role: Junior Frontend Developer
    period: "Sep 2020 - Jun 2021"
    description: >
      Context: first job out of school, on the live-ops admin
      tools for a mobile-game studio.

      Responsibilities: junior IC, building internal dashboards
      that the game-design team used for content tuning.

      Key contributions: shipped the season-tuning dashboard
      that replaced a daily spreadsheet handover; learned
      hands-on testing discipline through unit and integration
      tests required to land any change.

      Source of pride: a tool I built in my first six months
      is still in daily use four years later.
