+What happens when you add an API gateway in front of a decade-old monolith serving thousands of partners? At Mews, we discovered our APIs were being used in ways we never imagined. Join me to learn what we broke, what surprised us, and how we fixed it.

+I learned about burnout the hard way—by having several of them, including a Christmas Eve spent in the hospital hooked up to tubes. I wish I had recognized the signs earlier. You don’t have to hit that wall like I did. In this talk, I’ll share how to see burnout coming and what to do about it.

+It’s always hard to explain what DevOps is or what you actually do. To your spouse, to your friends, to your family, hell even to your dentist. After this talk, you might actually be able to get it right and they might finally figure out why do you mention containers so often.

+I’ve been crafting software for 23 years—long enough to remember the joy of debugging for Internet Explorer 4.0 and Netscape Navigator. My first software ran on an 8-bit computer, and I wrote my first “serious” desktop app for Windows 95 using Delphi 3 (Object Pascal). Over the years, I’ve worn many hats: running my own web hosting company complete with a self-built “datacenter” in 2008, diving into mobile app development for the iPhone in 2009, and moving to cloud-based web applications in 2010.
+
+My path has zigzagged between engineering and leadership, but since 2018, I’ve leaned fully into people management. Currently, I lead IT, Cybersecurity, CloudOps, and Technical Writing at FINN, a German scale-up making mobility frictionless and flexible for both B2C and B2B customers. I thrive at the intersection of technology and security, problem-solving, and building teams that drive innovation.

+Head of Engineering at Labyrinth Labs TLDR DevOps newsletter Curator
+My main focus is designing full-featured cloud infrastructures on AWS and Azure. Over the past couple of years, I gained experience building robust, auto-scaled, and highly-available cloud environments for many customers and applications, utilising a large set of tools and technologies during the process, mainly revolving around Kubernetes and Serverless. I like to work on challenging tasks, and always want to learn something new. I’ve wrote couple of blog posts mainly focused on observability tools and challenges I needed to solve and developed/contributed to couple of open-source tools used across the DevOps community.
