**PLEASE NOTE THE ADDRESS CHANGE! We're now at [w3hub.berlin](https://w3hub.berlin)** [Qase](https://qase.io) is presenting the **twelfth** Meetup on Quality Engineering in Berlin. As usual, we’re bringing you three deep-dive talks, **but also something extremely new and exciting — food testing activity. Don't worry, we won't be the test subjects, we will feed the spectrometer and see if our tests pass or fail :)** **AGENDA** **1\. Sebastian Kasanmascheff\, CEO/Owner @ Altum Solutions:** ***Wetware QA Jumpstart: Hands-On Spectrometer Demo*** Did last meetup’s “Food QA: Testing Tasting” session whet your appetite for wetware testing? Well here is an invitation to turn theory into practice with a live showcase of the device that taste-tests like a human, namely, the spectrometer. Take a leap from the familiar realms of software and hardware into the exotic world of wetware: translate between computer bits and chemical bonds, complement your programmer hoodie with a lab coat, and let us test what is in our food: \- How much protein is really in your protein powder? \- Can you trust the fat content values on your milk packaging? \- What ingredients are hiding in your favourite fast food meal? Learn how to answer such questions by joining the Altum Solutions team for an end-to-end spectroscopy workflow: from sample preparation to ML/AI-enhanced scientific analysis. This same wetware QA pipeline empowers sustainable lab automation across Big Food, AgriTech, and Pharma 4.0. **BYOB — Bring Your Own Bytes/Bites** **2\. Jaideep Naik\, Senior Software Engineer: *The Migration Hell: From Ghost Inspector to Cypress*** Jaideep will share his lessons from a 12-month test automation migration from Ghost Inspector (low-code) to Cypress (code-first). Limited planning led to flaky tests, slow CI pipelines, and lost trust in automation. Covers the key challenges — skills gap moving to JavaScript, tightly coupled tests, inefficient Page Object Model, UI-based auth bottlenecks, static test data, no coding standards — and the solutions that fixed them: phased migration, page-based POM with standardized locators, API-based auth, dynamic test data, and PR reviews from the start. **3\. Radik Zagirov\, Founder @ Agentiqa: Quality Is Binary: Why Your Coverage Metrics Don't Matter After the First Escalation** Radik argues that shipping code has become essentially free — AI writes code, CI/CD deploys it. But quality hasn't kept up. The bottleneck has shifted to people and processes, and business perceives quality as binary: everything works, or QA failed. One escalation erases months of coverage improvements and process building. Radik will share his understanding, that the answer isn't better testing but rather better communication. How to explain QA's value in the language of money, risk, and speed, and how to build "opportunity tunnels" — systematic channels that make QA's impact visible before an incident forces the conversation. **4\. Anupam Krishnamurthy\, Head of AI Testing @ TestSolutions GmbH:** **Ensemble Testing of an LLM Application** Earlier in November, Anupam demonstrated how we could test LLMs by using the LLM-as-a-judge approach. In that session, somebody asked, how can we trust an LLM to judge another LLM? In this session, we put LLM judges to the test. We'll do some live testing to have an LLM judge evaluate an existing RAG application. We'll then put up the results on the big screen and take a look together, to verify if our LLM judge is working as expected. In other words, everybody in the room will judge the judge. Can an LLM judge survive the scrutiny of a hundred pair of expert eyes? Come and find out in this live ensemble testing session.

Empower your soul by joining us for insights into the energy of the week and how to direct that energy in your life. Participate in practical workshops, experience consciousness-expanding meditations, and study spiritual wisdom that gives you real-life advantages. All classes are based on key wisdom contained in the Zohar, the ancient kabbalistic text that decodes the Torah's hidden messages. Quite simply, the Zohar is a manual for the days and weeks of our life. It helps you understand the spiritual laws of the universe so that you may find fulfillment in life and seize the opportunities before you on any given day.

**ESMT Insight Hour with Paul M. Achleitner** **Schedule:** 5:30 p.m. - Registration opens 6:00 p.m. - Welcome from host, ESMT Berlin 6:05 p.m. - Talk of Paul M. Achleitner 6:30 p.m. - Discussion and Q&A 7:00 p.m. - Networking, drinks and nibbles will be provided 8:30 p.m. - Close Experience used to accumulate slowly. Today, decisions travel instantly, legitimacy can evaporate overnight, and leaders operate under permanent public scrutiny. So how do you lead and stay legitimate in a world that no longer feels stable? In this ESMT Insight Hour, **[Paul M. Achleitner](https://www.linkedin.com/in/paul-achleitner/)** joins us for a moderated conversation on leadership, corporate legitimacy, and performance in times of geopolitical disruption, digital transparency, and shifting societal expectations. Drawing on more than four decades across Goldman Sachs, Allianz, Deutsche Bank, and multiple supervisory boards, and reflecting the themes of his recent book, *Accelerate Your Experience: Principles for Success in a Fluid World*, Achleitner proposes three interconnected dimensions of modern management: * **Legitimacy** – why companies must earn their place in society beyond financial performance * **Performance** – how sustained value creation requires focus, discipline, and strategic clarity * **Leadership** – what integrity, intellectual humility, and judgment mean in an era of permanent visibility Rather than offering prescriptions, he distills experience into principles on stakeholder dynamics, public attention, geopolitical disruption, AI, crisis management, and the realities of “muddling through.” The conversation will explore: * Why legitimacy has become the decisive constraint for corporations * How leaders balance long-term value creation with short-term scrutiny * What performance really means when underperformance becomes normalized * The evolving role of boards in turbulent environments * Whether experience can, in fact, be “accelerated” Join us for an hour of reflection on leadership under pressure and on what it takes to remain effective, credible, and resilient. Moderated by **[Jörg Rocholl](https://esmt.berlin/person/jorg-rocholl)**[,](https://esmt.berlin/person/jorg-rocholl) President, ESMT Berlin. **About the speaker** **[Paul M.
