Reliability at Scale – With Bruno Paulino (N26)

🎙 About the Podcast:
Señors @ Scale is a no-fluff engineering podcast hosted by Neciu Dan — diving into the real-world chaos of scaling systems, teams, and yourself. From production bugs to platform bets, we sit down with senior engineers to discuss the scars, strategies, and lessons that truly matter.

In this episode, host Neciu Dan sits down with Bruno Paulino, Tech Lead at N26, to unpack how reliability, experimentation, and platform culture shape one of Europe’s most trusted digital banks.

Bruno’s path is anything but ordinary — from serving as a police officer in Brazil to leading FinTech engineering teams at scale. He shares how N26 builds server-driven UIs, runs AI-powered customer support, and balances speed vs reliability when every deploy touches millions of users.

They break down:

How server-driven UI lets N26 ship features in minutes
Why CI/CD pipelines are the backbone of reliability
What it means to trade speed for resilience in FinTech
How Statsig changed experimentation culture company-wide
Lessons from production outages and post-mortems
Why strong developer experience drives safer systems

It’s a deep dive into the real architecture, trade-offs, and human decisions behind reliable banking systems at scale.

🎧 Whether you’re scaling a FinTech product, managing CI/CD pipelines, or just trying to keep production sane, this one’s for you.
