The **Digitec Galaxus Product Development Meet-Up** is back — this time diving into **recommender systems** with two talks bridging data science and engineering practice. **Talk 1: Insights from Building and Operating a Recommender System for Migros Supermarkets** *Max Nolte – Data Scientist & Team Lead at Supermarkt IT, Migros-Genossenschafts-Bund* When you think of a Migros supermarket, you don't usually think about recommender systems. Over the past four years, my team and I have built and operated the engine behind personalized Cumulus coupons and a few other digital touchpoints. I'll share how it works, why we invest in it at a brick‑and‑mortar retailer, and what we've learned, covering data, models, measurement, and the practical realities of running it day to day. **Talk 2: Recommendations at Digitec Galaxus — From Data Science to Engineering Practice** *Michael Weiss, Senior Software Engineer & Robert Rosenbach, Senior Data Scientist – Digitec Galaxus* How do you go from a promising model to a recommender system that is fast, scalable, and maintainable in production? We will walk through the Digitec Galaxus recommendation stack end to end: the engineering architecture that keeps recommendations snappy and reliable, and the data-science side of model training — what to optimize for, which input signals matter, and the trade-offs involved in both. The two presentations will take roughly a combined hour, leaving plenty of time for discussions, questions, and exchange afterwards over drinks and snacks. Whether you come from a software engineering, data science, product, or any other background — we'd love to have you join us!

"Behind the Curtain" is a women’s group built around real conversations and genuine connection. It’s a place where you can show up as yourself, talk about the things that actually matter, and feel truly heard — without pressure and without judgment. We intentionally leave work, small talk and our phones at the door, making space instead for honest stories, thoughtful questions and meaningful connection. To keep the space intimate and make sure everyone has room, spots for each gathering are limited. While each event stands on its own, the hope is that familiar faces will return over time, allowing trust to grow and real friendships to form. Whether you come with something on your heart or simply to hold space for others, you’re welcome here exactly as you are.

A decade. Hundreds of conversations, ideas, and inspirations. And we're celebrating with a meetup that truly delivers. Three exceptional speakers, topics that matter, and plenty of room for what has made this meetup special for 10 years: real people, real conversations, real networking. **The Evening at a Glance** 17:30 Doors open, first drinks, familiar faces and new ones 18:00 Welcome and a brief look back at 10 years of DevOps Meetup Zurich 18:15–18:45 **Claws in the Dark: Bringing DevSecOps to Legacy Hardware with Robotics and Playwright** by Alexander Friesen 18:45–19:15 **Beyond Agile: Structuring Organizations for Real Autonomy** by Lea Düker 19:15–19:25 Short break 19:25–19:55 **From Bottlenecks to Flow: OKRs, Value Stream Management, and Governance Done Right** by Vasileios Konofaos 19:55–20:15 Panel discussion with all three speakers 20:15 Networking, Open Space, snacks, drinks, and anniversary cake 🎂 **Claws in the Dark: Bringing DevSecOps to Legacy Hardware with Robotics and Playwright** What do you do when your software’s "deployment target" is a piece of security hardware embedded in a concrete wall for 20 years? In the world of access control, we don't have the luxury of "move fast and break things"—if the integration fails, the door stays locked. For decades, hardware development at Primion relied on manual bit-shifting, incomplete specifications, and the "read, write, and pray" method. When the pandemic decentralized our R&D department—scattering 60 developers across Europe—the traditional model of physical bench testing collapsed. We couldn't send a lab to everyone’s home, so we brought the developers to the lab through robotics. In this session, we deep-dive into how we bridged the physical-digital divide by building a fully automated hardware-in-the-loop (HIL) testing farm. We will explore: * The Architecture: How we orchestrate GitLab CI, Azure ephemeral environments, and Playwright to drive physical interactions. * The Hardware Hack: How a 200 CHF robotic claw replaced manual testing, allowing developers to "touch" hardware from anywhere in the world. * The Shift-Left Strategy: Moving from "praying for compatibility" to robust integration testing that catches bit-level errors before they ever hit the factory floor. * Scaling on a Budget: How a single working student scaled our setup to 20+ (and rising) automated test cells. Join us to see how "claws moving in the dark" turned hardware debugging from a nightmare into a breeze, and learn how to apply DevSecOps principles to the most stubborn, physical environments. **Alexander Friesen** Aexander is a **Lead IT Architect** with over a decade of experience in software architecture and technical leadership. He specializes in building and scaling modern ecosystems for major enterprises like **Swisscard** and **Siemens**. DevOps & Platform Engineering Highlights * **Platform Leadership:** Directed technical strategy for Siemens’ IoT flagship "BuildingX" and managed multi-million dollar budgets for large-scale SAFe trains. * **Automation & Compliance:** Expert in **DevSecOps**, achieving ISO27000 compliance through automated CI/CD pipelines and security scanning. * **Efficiency Gains:** Improved software team productivity by **30%** through the implementation of AI Ops and Internal Developer Platforms. * **Cloud Native Stack:** Certified **AWS Architect** with deep expertise in Kubernetes, Terraform, Serverless, and **Data Mesh** architectures. * **Global Teams:** Proven track record of leading cross-functional engineering teams across Switzerland, Germany, the USA, and India. **Beyond Agile: Structuring Organizations for Real Autonomy** Many organizations invest in agile methods, DevOps, and new technologies, and yet the desired impact on collaboration, accountability, and decision-making often fails to materialize. A key lever for change lies in how organizations are structured. This talk provides an introduction to Holacracy as a model for radical self-organization and places it within the broader landscape of organizational development. It explains what defines Holacracy, the principles behind it, and the problems it aims to address. The focus, however, is not solely on the organizational model. The talk also presents concrete tools and practices of self-organization, such as clear role definitions, structured decision-making processes, and transparent governance, that can be applied regardless of the organizational structure in place. **Lea Düker** * Since 2024: IT Project Manager and Scrum Master at digital agency Unic AG * 2021–2024: Project Manager and Deputy Head of IT at the Building Department of the City of Zurich * 2018–2021: Consultant for Process Management at Join GmbH * 2016–2018: Master's degree in Business Management with a specialization in Process Management **From Bottlenecks to Flow: OKRs, Value Stream Management, and Governance Done Right** In our session, we'll be delving into the advanced flow engineering practices we've implemented at KPMG CH for our Cloud Platform. These methods have truly transformed how we deliver outcomes—faster, safer, and with an even greater level of satisfaction. During the session, we'll take a closer look at how we leverage OKRs to align teams and drive strategic goals, and how Value Stream Management helps us optimize workflow and eliminate bottlenecks. Our robust Governance model will also be discussed, highlighting how we maintain compliance without sacrificing agility. Beyond sharing the technical details, we'll reflect on the lessons learned and valuable insights we've gained throughout our journey. Our goal is to provide actionable takeaways that will benefit the DevOps community and inspire organizations seeking to enhance their delivery pipelines and nurture a culture of continuous improvement. **Vasileios Konofaos** Head of Business Services CH Group Digital Vasileios Konofaos is a seasoned technology leader with more than 20 years of experience driving large‑scale software engineering, cloud infrastructure, and digital transformation initiatives.

It all sounded straight forward. Then the project started... Join us for an informal evening with fellow Agile practitioners, Scrum Masters, project managers, coaches, and anyone working with change, delivery, or transformation. We’ll meet at a local pizzeria, have some good food, and talk about the things that usually come up once the theory meets reality — challenges, lessons learned, different approaches, and questions we’re still figuring out. Nothing formal, just a chance to exchange ideas, meet people from the community, and have interesting conversations. Because some of the best discussions don’t happen in meeting rooms. They happen in the second floor private room of a pizzeria. 🍕 **The venue:** Da Raffaele brings a slice of Naples to the heart of Zürich's Altstadt. Think 48-hour dough, a 500°C wood-fired oven, and an amazing pizza. Two minutes from Central, close to HB — easy for everyone coming from across the city or the S-Bahn.

AI is changing how art is made. But when does it stop being your work and start being the machine’s? This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation? We encourage audience participation during this event that will be moderated by Chris Slee. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories. When you become free of your past, you will be free from stress, anger, anxiety and depression. Studies show that negative emotions can affect your health. By being free of negative emotions, believe it or not, you will most likely even look younger, feel more energetic, and become healthier!
