About Manuel

I'm an experienced and pragmatic software engineer who thrives on building impactful features while maintaining high standards for code quality and performance. I'm equally passionate about developer experience, always seeking ways to reduce friction, share knowledge, and empower both myself and my colleagues to move faster with confidence. I like working in fast-paced environments.


I'm primarily looking for engineering roles, but could also be interested in transitioning into an entry-level engineering manager position, combining technical contributions with team support. I find greater satisfaction in helping others succeed than in being recognized for my own achievements.

Experience

  • Gorgias
    Frontend Engineer
    September 2021 - Today (4 years and 9 months)
    Some key contribitions:
    • Custom Actions Enabled our merchants to build and trigger "custom actions" via a simple UI, allowing seamless interaction with external APIs. A templating mechanism would let them compose HTTP requests using all the data available across Gorgias. It was fullstack development, using React on the frontend and Python on the backend. Among other benefits, this contributed to increase revenue by helping attract several large companies to adopt Gorgias.
    • Revamped a core product to reduce churn Led the rapid redesign of a major product feature that was underperforming and contributing to customer churn. In a tight timeline, we delivered a revamped React-based solution while simultaneously refactoring legacy code. This not only brought churn close to zero but also let other developers easily build more feature on top of it.
  • Crédit Agricole CIB
    Frontend Engineer
    April 2021 - September 2021 (5 months)

    Developed a real-time financial transaction tracking application using TypeScript and React, capable of handling hundreds of thousands of records and supporting advanced risk analysis.
  • Ministère des solidarités et de la santé
    Frontend Engineer
    February 2019 - March 2021 (2 years and 1 month)
    France
    Working within the Digital Factory of the French social ministries, I spent two years helping build and refine a high-impact, user-centered public platform. The work emphasized clarity, accessibility, privacy, performance, SEO, open source collaboration, and long-term maintainability.
    Following its first year online, the platform achieved over 3 million visits and ranked above service-public.fr on certain legal queries.
