Abstract:
Zappi, a growing scale-up, faced a make-or-break moment: to unlock the next generation of insights, it needed a purpose-built Lakehouse platform - fast. With limited runway after previous setbacks, it took a bold gamble: adopting Elixir, despite having zero prior experience with the language.
This high-stakes choice paid off. Elixir’s concurrency model, scalability, and “Let it crash” philosophy were a force multiplier for us to design a robust, decoupled system. From onboarding Elixir newcomers to overcoming technical challenges, we learned invaluable lessons about maximizing delivery under pressure.
In this talk Herman shares:

Why we chose Elixir.

Strategies for rapidly onboarding a team with no Elixir experience.

How Elixir’s unique principles turned challenges into opportunities.

Practical insights for teams betting on new technologies in high-risk projects.
Whether you’re a tech lead or engineer, this story offers real-world guidance for innovating under constraints.
