Why this program matters

  • Without mastering Prettier, your source code remains inconsistent, multiplying merge conflicts and endless team reviews.

  • Developers lose an average of 15 to 20 hours per week on manual reformatting, amounting to more than 50 000 € in annual productivity per team of 5 people.

  • 60 % of production bugs are tied to neglected formatting errors, causing costly downtimes and critical project delays.

  • Every month without automatic standardization, your company risks fatal loss of competitiveness, and your career stagnates against more agile juniors.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
