How platform engineering saves 99% in A/B testing costs, enabling innovation for 50M users

Maryna Rybalko shows how platform engineering and no-code tools can transform idea validation in large enterprises. At Jooble, a global job platform with over 50M monthly active users in 67 countries, traditional experimentation was slow, expensive, and engineering-heavy. By introducing a no-code A/B testing tool, the team cut validation costs by 99% and reduced test cycles to 3 days, enabling employees to validate hypotheses quickly and drive innovation.

Key takeaways include:
• How platform engineering drives cost efficiency and accelerates innovation at scale.
• How to leverage existing technology to design solutions for hypothesis validation.
• Lessons learned from failures and successes.
• How a no-code solution helped transform the organizational culture.
