My values

Care, creativity, equity, transparency: four human values at the heart of SolaFox.

Care

I design for humans, with humans. Care comes with respect: for the people I work with and the environment I operate in.

In practice

  • Sustainable, low-impact code and digital sobriety.
  • A healthy, respectful and inclusive collaboration setting.

Creativity

I value the freedom to act and experiment. The best solutions come from daring to look at problems differently.

In practice

  • Continuous learning and active tech watch.
  • Sharing knowledge with clients and the wider community.
  • Support for initiatives and unconventional ideas.

Equity

I believe in a tech that is accessible to all, fostering diversity and fairness in every interaction.

In practice

  • Designing software accessible to all user profiles.
  • Fair and inclusive collaboration at every stage of a project.
  • Awareness of unconscious bias, valuing differences.

Transparency

I build long-term relationships through honest and open communication.

In practice

  • Sharing progress and difficulties with clarity.
  • Being honest about the strengths and limits of my solutions.
  • Regular feedback, both ways.

I build solutions that actually fit your needs and constraints. Available to discuss your projects.
