**Sponsored by:** ***\- ACP*** ***\- TD SYNNEX*** ***\- Technopark Winterthur*** **Partner-led and partner-branded by**: ***Microsoft*** Speakers: * Firas Cheaib (ACP) – When Models Become the Commodity * Victor Chibotaru(LogicStar AI) – Shipping Faster, Drowning Sooner Abstract: When Models Become the Commodity ACP Engineering works extensively with LLMs to write production code across a small team. What makes that work is not the models, but the groundwork laid before them: a portfolio of Python projects sharing the same tooling, structure, tests, CI, and linters, the same conditions that already made the codebase easy for humans to navigate. That foundation is what powers the current build of ACP-M, ACP's industrial IoT platform for manufacturing customers, and an early agentic-loop prototype now running internally. The next step is enabling customers to automate their own operations the same way. Doing that requires the same kind of preparation on their side: turning fragmented operational data into knowledge graphs, unified namespaces, and typed semantic layers, so that agents act on information that is short, focused, and reliable. Once that environment exists, the model becomes a commodity. What matters is enterprise processes and domain knowledge, not which model happens to be in fashion that quarter. Attendees will leave with a concrete way to assess whether their own environment is ready for agents at all, and what it takes to get there -- Shipping Faster, Drowning Sooner AI ships your features faster than ever, but it also ships bugs faster than ever. Code got cheap, maintenance didn't: customer complaints stack up, Sentry alerts overflow, and triaging the pile is still as expensive as it ever was. I'll show how LogicStar finds bugs across your Sentry, Jira and codebase, separates signal from noise, and helps your team fix issues that matter.

I'm really excited to announce our next Meet Up event. It will take place at Core studio in Rennweg Rennweg 12, 8001 Zurich. The is dedicated to everyone who likes the idea of exercising with the music, dancing and learning a bit of ballet. Find out how to set up the a great posture, learn about body conditioning as well as mind & body connection. Unlike at most general adult ballet classes we will show you how exercise with the precision and focus, getting great results. A great class for those that are just starting with ballet, or those who are conscious about using their body precisely and targeting correct muscle groups in order to achieve greater results. The class is structured as a unique combination of ballet exercises, Pilates, stretching and motivation. Open to all levels. You will need to bring a smile, some water and wear comfortable exercise cloths. The class will be 60 minutes which should be more than enough to get those muscles warmed up and you posturised ready for the next session. There's a small cost to cover the venue and facilities - CHF 40.- For more details about the training provider please see: https://www.balletbodysculpture.com/ballet-body-sculpture-classes-in-zurich

Web Zurich presents inspiring talks all about the web. Join us for the Mai 2026 meetup! We will have three talks as well as chit-chat and drinks. Whatapp: [https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK](https://chat.whatsapp.com/FxOfVTK9nf431xHtVl3eGK) Website: [https://webzurich.ch](https://webzurich.ch) 18:30 \~ 19:00 Arrival time with drinks, chat 19:00 \~ 19:10 Welcome and introduction 19:10 \~ 19:30 *Alex Suzuki* **Monetizing JavaScript: Building Profitable Products as a Solo Developer** Lessons learned from building and launching a commercial JavaScript library as a solo developer. 19:30 \~ 19:50 *Hugo Sousa* **Ten times tea** I'm building a programming language. When I got to the frontend, I ran into a problem: React's mental model is elegant, but the mental model is at odds with the code. Hooks, effects, and render passes create a runtime that bears little resemblance to the code we write. The Elm programming language works differently and its architecture (TEA = The Elm Architecture) has been adopted by other tools over the years. So I copied it as well. My language embeds TEA at the language level, not as a library. This unlocks time-travel debugging, reproducible application state and serializable bug reports that include the entire program state. This talk covers the quick introduction of my language, TEA, why TEA is the right fit and what becomes possible when the architecture is baked into the language itself. 19:50 \~ 20:10 *Marco Gähler* **Software testing** Many old software projects don't have any tests - if the code works, why should you bother with tests? Well, you really should bother, because code changes all the time. During development, you keep adding new features which at times requires large scale modifications of the code that will inevitably alter existing functionality. And in existing projects, one still has to make updates once in a while, for example for security patches. These things will always break existing functionality and tests are the only remedy against this issue. In this talk, we will look at the basic idea of tests, how to implement them, what issues to look out for and how you can test pretty much any piece of code if your code base is well structured. 20:10 onward More drinks & chat We look forward to see you there!

Accessibility often feels overwhelming with all its guidelines, standards and edge cases. But in practice, meaningful improvements don’t require perfection. They require empathy and a sincere motivation to create a truly usable experience for all. In this talk, we share real learnings from UX and UI projects: what actually made a difference, where teams struggled, and how small, deliberate changes created a much more inclusive experience. You’ll walk away with a practical mindset and actionable ideas to start improving accessibility in your own projects — without waiting for the “perfect” solution.

The OWASP community is getting together for another meetup in May 2026! Join us for some security talks 🔐, good company 🤝, and a little aperitif 🍕. **Program:** **16:00** - **Doors open**: Grab a drink, meet old and new friends from the OWASP Switzerland community **16:30** - **Hello from OWASP Switzerland** **16:40 - Talk: AI-Driven Development Lifecycle (AI-DLC) (Markus Rollwagen, Senior Solutions Architect, AWS)** **17:25** **-** **(10min break)** **17:35 - Talk: Using HoneyPots to protect critical Infrastructure (Giulio Grazzi, Head IT Security, SRF)** **18:35** - **(10min break)** **18:45 - Talk: We Tried to Detect Prompt Injection in Coding Agents. Here's What Broke (Paulo Martins, Principal Security Engineer, GitLab)** **19:30 - Networking & Pizza 🍕 & Aperitif**🍷- Grab a bite and chat with old and new friends **Talks Details:** **AI-Driven Development Lifecycle (AI-DLC) (Markus):** Software development is undergoing a fundamental shift. AWS’s AI-Driven Development Lifecycle (AI-DLC) positions AI not as a mere assistant, but as a central collaborator across the entire SDLC — from requirements to deployment. In this session, we’ll explore how AI-DLC’s three phases — Inception, Construction, and Operations — redefine team workflows, and what this means for security: how AI enforces organization-specific security standards consistently, maintains human oversight at critical decision points, and ensures traceability from requirements to deployment. We’ll discuss the security opportunities and risks this methodology introduces, and how teams can adopt AI-DLC while keeping security a first-class citizen in every “bolt.” **Using HoneyPots to protect critical Infrastructure (Giulio):** How do you protect your critical infrastructure in the days of agentic ai and very limited options on your hosts? You need to get creative and use stone age tech. I’ll give you some insights, from our journey and pitfalls you might be facing (and should be avoided :)) **We Tried to Detect Prompt Injection in Coding Agents. Here's What Broke (Paulo):** As a community, we are delegating a significant part of our development workflow to agents, and as the use cases grow, the risk of prompt injection keeps increasing - to the point that it made it to the top of the OWASP LLM Top 10. In this talk, I'll explore the concept of "detect and prevent prompt injection" and why it is particularly hard to do for coding agents. **Speaker Details:** **Markus Rollwagen** Senior Solutions Architect at AWS, based in Switzerland Markus enjoys deep dive technical discussions, while keeping an eye on the big picture and the customer goals. With a software engineering background, he embraces infrastructure as code and is passionate about all things security. **Giulio Grazzi** Head IT Security, SRF From bike messaging to networking to infosec - always maximize never max out. Currently at Schweizer Radio und Fernsehen dealing with all Infosec topics, background in networking, embedded devices and mobile security. **Paulo Martin** Principal Security Engineer, GitLab since 2021 Now focused on AI security: prompt injection, sandboxing, and keeping agentic workflows from doing things they shouldn't.
