**About the talks:**

* **Talk 1: Chasing Operational Excellence in an Inherited Environment: Knowing What Good Looks Like Doesn’t Always Make It So**

After years of building teams from the ground up and successfully empowering autonomy, what happens when you inherit two decades of a "simple business"? How do you transform every aspect of that organization—while keeping it running smoothly and driving profitability at the same time? This talk explores the challenges, lessons, and opportunities of leading large-scale transformation in a legacy environment.

* **Talk 2: From vibe coding to spec-driven development**

Vibe coding, rapidly prototyping based on intuition, is gaining significant attention in software development. This session explores how developers can move beyond vibe coding to generate more consistent and repeatable outcomes through spec-driven development.

**Speaker Bio's:**
**1\. Brent McLean** is a commercially driven and strategic technology executive with over 20 years of experience leading product and platform transformations in online marketplaces, spanning horizontal classifieds, real estate, and automotive. He is recognized for delivering both top- and bottom-line impact through deep digital transformation and large-scale replatforming initiatives.

Brent began his journey as Technology Director for online classifieds at Fairfax Digital in Sydney before relocating to the Netherlands in 2010 to become CTO of Marktplaats. He later rose to CPTO of eBay Classifieds Group, where he led global product and technology teams across more than 10 countries. Following the group’s highly valued sale to Adevinta in 2021, Brent took on the role of Group CTO at Aviv Group, an Axel Springer company backed by KKR. Over four years, he guided the business through intensive transformation—an experience that tested every lesson from his career to date.

**2\. Gunnar Grosch** is a Principal Developer Advocate at AWS. A developer and engineer for over 25 years, and a former AWS Serverless Hero and AWS User Group Leader, he connects with developers worldwide to understand their needs and bring their voices into AWS, sharing code, insights, and lessons from the field.

Datadog User Group Amsterdam Meetup

I'm happy to announce another User Group meetup. This time we're - once again - welcomed by **[rackspace](https://www.rackspace.com/).**

I'll post the agenda as soon as I can confirm speakers. If you're interested in give a talk, feel free to reach out to me at marcel.drechsler@andsafe.de

All talks will be **presented in English**, to ensure that as many people as possible can participate and engage at this event.

\-\-\-\-\-\-

**🏠 18:00 - Arrival: Networking, Drinks & Snacks (30 min.)**
Grab yourself snacks & drinks and say hello to everybody else!

**📅 18:30 - What's Bad Telemetry Anyway? (30 min.)**
**🎙️**Speaker: Juraci Paixão Kröhling, Software Engineer & CNCF Ambassador @ **[OllyGarden](https://ollygarden.com/)**

The promise of "instrument all the things" often leads to an overgrown jungle of telemetry data—expensive, noisy, and surprisingly unhelpful when incidents strike. This talk examines what separates signal from noise in modern observability, explores the hidden costs of poorly curated telemetry, and provides practical strategies for cultivating data that actually serves your debugging needs instead of obscuring them.

**☕ 19:00 - Break (15 min.)**

**📅 19:15 - Recap of DASH25 (60 min.)**
**🎙️**Speaker: Alla Igityan, Enterprise Sales Engineer @ **[Datadog](https://www.datadoghq.com/)**

In this session, we'll get an overview of all the announcements made at Datadogs annual conference DASH and some surprise demos.

**🥗 20:15 - Drinks, Food & Networking**
Enjoy refreshments while networking with community peers!

**👋 21:00 - Goodbye, see you next time!**
