Scala Center

💼 Scala Days 2025 From August 19 to 21, 2025, the Scala Center had the pleasure of hosting Scala Days 2025 at the SwissTech Convention Center in Lausanne. The conference brought together around 300 participants from across the globe to share knowledge, innovation, and passion for the Scala ecosystem. Our Congress & Events team was proud to support the event by managing the registration platform, welcoming attendees, speakers, sponsors, and ensuring smooth logistics throughout the three-day event. In addition to the rich conference program, participants enjoyed memorable social activities, including a Community Party at PLATEFORME 10, a Speaker Dinner at Restaurant du Débarcadère, guided tours in Lavaux with wine tasting, a Master Chocolatier experience, and a Lausanne city tour for accompanying guests. A warm thank you to all partners and participants for contributing to the success of this inspiring edition, and to our clients, Darja Jovanovic, for their trust! #ScalaDays2025 #Scala #EPFL Team: Jonathan Da Fonseca, Amina N. and Gerald Howard (Lausanne Montreux Congress) ©Naomi Wenger

🎬 Episode 2 of our Scala Days 2025 interview series is here - give it up for our friend David A. G., Senior Scala & Data Engineer at Xebia and Scala Ambassador. David told us about his journey into Scala, the reasons behind choosing it, his workshop at Scala Days, and his impressions of the event. ✨ Don’t miss the next episodes - follow our series for more Scala stories! 💭 And what made you choose Scala? #Scala #ScalaDays

At Iterators, we believe that active participation in the global tech community is key to staying at the forefront of software innovation. This commitment recently took us to Scala Days 2025—organized by the Scala Center at EPFL (École Polytechnique Fédérale de Lausanne) and held at the SwissTech Convention Center in Lausanne—Scala’s own hometown. Scala Days remains a key gathering for developers, researchers, and business leaders from every corner of the #Scala ecosystem 🌎 The event offered a packed schedule—including hands-on workshops, in-depth discussions of real-world Scala use cases, explorations of emerging AI and ML in #functionalProgramming, and panels covering topics from developer experience to industry-scale deployments. More than that, it was a celebration of the Scala community—welcoming contributors, researchers, programmers, and enthusiasts to connect, share, and build the future together 💥 Representing #IteratorsHQ at the event was our managing partner, Łukasz Sowa, who continues to serve as a Scala Ambassador 💪 Through this role, Łukasz is engaged in fostering deeper connections within the Scala community, and supporting initiatives that advance the language and its usage across tech and business. Events like Scala Days provide a platform for Ambassadors to share practical insights, champion best practices, and help shape the direction of the Scala ecosystem 🚀 We were happy to attend #ScalaDays —not just for the inspiration and technical insights, but also for the opportunity to contribute to a thriving community united around excellence in software craftsmanship 💪

Thanks again for organising Scala Days to Scala Center and especially Darja Jovanovic, to all platinum, gold, silver and bronze sponsors (full list is available on their page). It was great time spent, feeling fully recharged. I was hesitant actually flying there, few reasons, one of them is it's not the first time, I had been at the same conference few years ago in another venue and wasn't sure if I could learn anything new really. However, no regrets, the quality is still high, the speakers are amazing, the topics are hot. Even the sponsors are not too boring! 😜 I fact, quite the opposite. I am certain that the swag from Gradle Inc. became a legend! 😁 Met so many interesting people, let's not loose connection. This works better when you travel alone. 😉 Very motivating and great learning experience. Bonuses: chance to see famous "Scala ladder 🪜", vibrant EPFL campus and cosy cities of Lausanne and Geneva. Functional programming and Scala are very much alive and still moving into right direction! And thanks to Workday who sponsored my trip (and special thanks to Rachel OToole who helped with that). Not good bye, but see you again soon.

I started playing around with Scala back in 2010, at the time no IDE just a text editor and a rough compiler with cryptic error messages. But a lot of new programing principles: immutability, functional programing, a strict type system. Refreshing and new, giving me the ability to write better more readable code, with less bugs, and less boilerplate. When we started RadiantFleet in 2015 it was the obvious programing language choice. Fast forward to today, and our company is writing all our solutions in the latest Scala 3, ScalaJs and Scala Native. More than a million lines of Scala code. The benefits I found, I saw in our team as well. Scala enabled us to provide more reliable functionality to our clients, and make us the developers more efficient, productive and happy. ScalaDays 2025, 15 years after my first introduction, and I find my self at the ScalaDays 2025 in Lausanne. I see the people whose videos I watched over and over again and I learned so much from in real life. It was a great experience. Big thank you to Martin Odersky and his team, Sébastien Doeraene, Stefan Zeiger, Haoyi Li and many others for creating the language and tools we work on every day, and to the Scala Center for organizing such a great event. #scaladays2025 #scala #scalajs #slick #playframework #epfl

Just had the pleasure of speaking at Scala Days 2025 in Lausanne!🇨🇭 I shared our experience with event sourcing and how separating write and read models with Scala case classes has helped us simplify domains, optimize queries, and keep systems evolving cleanly. Big thanks to Xebia who gave me the opportunity to go to Scala Days, the organizers, the Scala community, and everyone who joined the session. 🙏 And of course, I couldn’t miss taking a picture by the iconic EPFL stairs that inspired the Scala logo! #ScalaDays #Scala #EventSourcing #CQRS #FunctionalProgramming
