Quality Engineering meetup
Thu, Jul 16, 4:00 PM*In collaboration with* *Deutsche Bank*, *[Qase](https://qase.io/) is presenting the **thirteenth** Meetup on Quality Engineering in Berlin.* *We’re bringing you three deep-dive talks: all designed to challenge the way you think about quality, testing, and collaboration.* *As always, expect great conversations, snacks, and drinks. See you there!* **AGENDA** **1\. Olga Bokova @ Deutsche Bank: *Testing the Nanoseconds: A Decade of High-Frequency Trading QA Evolution*** High-frequency trading systems operate at the edge of technology, where latency is measured in nanoseconds and every delay can translate directly into financial impact. In this environment, traditional QA approaches quickly break down, e.g. functional correctness alone is no longer enough. In this talk, Olga will share a real-world journey of how QA evolved over the past decade within high-performance trading systems. We’ll explore the challenges of testing ultra-low latency platforms, handling massive market data streams, and ensuring deterministic behaviour in highly distributed environments. Olga will walk us through how fragmented testing approaches led to inefficiency, duplication, and scalability issues, and how they transitioned toward a unified, domain-level testing framework built around simulation and controlled environments. You’ll learn how treating testing infrastructure as an engineering product helped us reduce complexity, increase reliability, and enable performance testing at realistic market scale. Along the way, Olga will share practical lessons, trade-offs, and what they chose to abandon (not just what we built). **2\. Neha\-B Yadav @ Deutsche Bank: *Secure AI, Smarter Testing: How QA Teams Can Shift Left Efficiently*** Now as ever, staying effective and efficient requires more than just strong testing fundamentals, but also intelligent orchestration of tools, data, and automation. Neha will focus in this talk on three key dimensions: how to stay effective with the help of AI-driven test workflows, how to remain relevant with modern engineering practices and enterprise tooling, and how to continuously upskill in an ecosystem of automation, AI agents, and integrated test platforms. Neha will share her approach with shifting testing left, proactive defect prevention, early test design, and proper continuous integration. The session will highlight techniques such as test-driven development, early collaboration between QA and engineering, and integrating validation into CI/CD pipelines to reduce downstream risks. **3\. Vitaly Sharovatov @ Qase: Leading Cost Cutting Initiatives by Improving Quality** More and more companies are cutting costs and doing layoffs, and QA is often among the first to be cut. Yet it is precisely QA folks who can help cut costs while improving quality. In this talk, Vitaly suggests ways we all can lead cost cutting discussions to make things right and either reduce or prevent layoffs. Partner with Customer Support to identify which escaped defects cost the most in ticket handling and escalations. Partner with Sales to identify which bugs put renewals and expansions at risk. Add Finance for SLA credits and refunds, and Engineering for incident response and hotfix effort. Add it all up, and you get external failure costs. After that, quantify internal failure costs like rework, retesting, queues, and waste. We will turn these numbers into a cost cutting proposal that managers understand: reduce the priciest external failure costs first, then reduce internal failure costs, by improving the way we build quality in. You will leave with a simple template for collecting the numbers with other departments, doing the calculations, and proposing specific process changes. Let's be the people who cut failure costs, not the people who get cut!

[Date changed] Berliner Bitcoin-Stammtisch @ Friedel Richter
Sat, Jul 4, 5:00 PM[Date changed!] Welcome to the Berliner Bitcoin-Stammtisch, where we gather to talk about the digital currency that's worth more than gold and sometimes causes more drama than a Netflix series. Join our tribe of business beings, developers, and activists who believe that Bitcoin is the future of money, and El Salvador seems to agree! Here you can learn the ropes of Bitcoin, from buying your first fraction to safely storing your private keys. Our current hangout spot is Friedel Richter on Torstraße, because ROOM77 is closed until the last block is mined. You can pay in Bitcoin ₿ or Lightning ⚡ and enjoy awesome regional food with an international twist. So come join the fun, the food, and the revolution! We're waiting for you. 🍔🍔🍔
