Highlights of the Rev/Dev 2025

Revolut's annual dev event in Barcelona: talks on scaling event-streaming and data aggregators, plus networking over Moritz beer.

On Monday, March 31st, the annual Rev/Dev event took place at the Moritz factory in Barcelona, and I had the incredible opportunity to attend!

The Revolut team put a lot of care into organizing the event and were very attentive to all attendees.

We kicked things off with a warm welcome from Svetlana Kochkina, Head of Employer Branding at Revolut. She gave us a brief overview of the company's history, highlighting key milestones and future goals.

Following Svetlana's introduction, we enjoyed two insightful talks on how Revolut has tackled some of its most significant technical challenges:

A tale of scaling an event-streaming platform

By César Luis Alvargonzález, Lead Software Engineer

It was fascinating to learn about the challenges involved in managing the vast amount of event data generated by the Revolut ecosystem. César explained how his team scaled their database solutions to ensure high performance and reliability while handling billions of events — an ever-growing number.

Lessons learned on building data aggregators: an engineering perspective

By Xabier Burgos Gimeno, Senior Backend Engineer

One thing I hadn't fully grasped before (but had suspected) was just how complex and tricky it is to integrate a platform with multiple data providers across all the countries where Revolut operates. Xabier gave us a fantastic overview of how his team tackles this challenge — and, surprisingly, how fun it can be! Each new provider is different, meaning there's always something new to learn.

As the event drew to a close, Revolut had planned a generous and highly productive networking session. We had the chance to connect with fellow attendees while enjoying original Moritz beers and a selection of delicious snacks.

I want to sincerely thank Revolut for inviting me to this amazing experience and all the speakers for sharing a glimpse of their work and purpose at Revolut. See you next year!
