Our first CTO Roundtable Berlin in 2026: **How Can I Become a Better CTO**: Many CTOs step into the role through strong technical expertise, only to discover that success increasingly depends on leadership, communication, and influence. This session will focus on the transition from hands-on technical leadership to broader organizational impact. We will discuss which skills matter most at different company stages, how to shift from problem-solver to decision-enabler, and how to continue growing as a CTO while staying credible with engineering teams. Practical advice, common pitfalls, and personal development strategies will be shared to help CTOs evolve their role intentionally.

Save the date! The Mozilla Meetup series continues with talks focused on modern web technologies. To account for typical **no-show rates**, we’ve opened more RSVP spots than we can physically accommodate. Based on our last event, only about 36 of 100 registered participants (including Mozillians) attended in person. **We will admit attendees on a first-come, first-served basis and will need to close the doors once we reach room capacity (around 50 people).** Note that this event operates under the [Mozilla Community Participation Guidelines](https://www.mozilla.org/about/governance/policies/participation/). **18:00** \- Doors open **18:30** \- Tracking \(Protection\) Everywhere There are a variety of tracking vectors on the web. But how exactly does this tracking work and what mechanism do we have available to protect our privacy? This talk takes a closer look at the many anti-tracking mechanisms Firefox uses to protect its users, and discusses the threat models behind them and the practical protection they provide. Bio: Manuel Bucher is a software engineer on the Firefox Privacy team working on anti-tracking in Firefox **19:30:** No Servers, No APIs: AI in the Browser I’ll present how modern web technologies make it possible to run AI models directly in the browser combining WebLLM and WebAssembly to deliver powerful, privacy-preserving client-side AI experiences. For more context, here’s a related article I wrote for Mozilla AI: [https://blog.mozilla.ai/3w-for-in-browser-ai-webllm-wasm-webworkers/](https://blog.mozilla.ai/3w-for-in-browser-ai-webllm-wasm-webworkers/) **Bio:** Barış Güler is an engineering leader working on in-browser AI systems that leverage WebLLM, WASM, and web platform features to bring AI inference and tooling into client environments. He writes about web-native AI and open-source approaches to privacy-first machine intelligence (and a Rust fan, for sure).

As always, please make use of the lightning talks and talk about anything you like: a problem that you'd like help with, a thing you've built, or a hobby you like. Doesn't have to be Django, doesn't even have to be tech! **18:30 Doors open** **19:00 Main talk by Johannes Tigges** **19:30 Lightning talks** **19:45 Get eatin'** This event is governed by the **[Berlin code of conduct](https://berlincodeofconduct.org/de/).** We want this to be a safe space for all. Any questions and concerns can always be directed towards the organizers Lara Krämer (lara.softwareengineer@gmail.com) and Markus Binsteiner (markus@frkl.dev) before, at and after the event. **Accessibility information:** The main entrance door to the building is quite heavy and must be opened manually, as does the office door. There are a few steps leading to the elevator, along with a relatively steep ramp built into those stairs.

In this session, we’ll explore how GitHub Spec-Kit enables teams to treat specifications as first-class artifacts—living documents that drive architecture, implementation, and verification. You’ll learn how Spec-Kit helps teams clearly express intent using structured, version-controlled specs that live alongside code. We’ll walk through a practical workflow that starts with defining system behavior and constraints, then progressively refines those specs into testable, automatable outcomes. Along the way, we’ll show how specs can reduce ambiguity, improve cross-functional collaboration, and make design decisions explicit before a single line of production code is written. This talk will cover: --What spec-driven development is (and what it isn’t) --How GitHub Spec-Kit fits into modern developer workflows --Using specs to align product, engineering, and AI-assisted development --Real-world examples of turning specs into implementations with confidence Whether you’re building greenfield systems, integrating AI into your stack, or trying to reduce costly rework, spec-driven development offers a scalable way to move faster without sacrificing clarity. Attendees will leave with concrete patterns and a clear mental model for adopting GitHub Spec-Kit in their own projects. **YouTube Link** TBA
