Development Principles at Zeffy:

• We always optimize the ratio impact / effort, it’s what we call Zeffy perfectionism, as opposed as classic perfectionism.

• We avoid over-engineering and anticipating problems too much, the codebase stays clean and efficient.

• Every 2 months, we set ourselves targets on the 4 following dimensions: efficiency, security, stability and performance.

• Trust and ownership: every target is clear and owned by one person who is flexible to reach it; owned by one person doesn’t mean working alone on it.

• Continuous improvement: We regularly review and refine our processes, promoting a culture of learning and growth.
