Application Development

Join us for our first [Kyverno](https://kyverno.io/)-dedicated meetup before the summer break 🌴 We want to thank **[Schwarz Digits Spain](https://www.linkedin.com/company/schwarz-digits-spain/)** for kindly hosting us for this evening of learning and networking! **🧭** **What is Kyverno?** **[Kyverno](https://kyverno.io/)** is a CNCF-graduated, Kubernetes-native policy engine. Unlike other tools that require learning a new programming language, Kyverno allows you to manage cluster governance, security, and compliance using familiar Kubernetes manifests. With zero coding required, you can easily: * **Validate**: Block non-compliant resources before they hit your cluster. * **Mutate**: Automatically inject sidecars, labels, or configurations on the fly. * **Generate**: Automatically create new resources (such as NetworkPolicies or ConfigMaps) when a new namespace is provisioned. **📅 Agenda** * **18:30-18:45**. Doors Open. * **18:45-19:45**. Talks (see below). * **19:45-20:30**. Mingling and food. **📍Location:** c/ Bergara 13\, Barcelona \| [https://maps.app.goo.gl/zd6h3BGzHNxgAgjT6](https://maps.app.goo.gl/zd6h3BGzHNxgAgjT6) **🎙️ Talks** **1️⃣ The Kyverno Five: New Policy Types And What You Can Do With Them**, [Cortney Nickerson](https://www.linkedin.com/in/cortney-nickerson-26836413a/) *\- Head of Community at [Nirmata](https://nirmata.com)* (Talk in English 🇬🇧) As Kubernetes has evolved, so has Kyverno! This talk provides a tour of the five new Kyverno policy types, ValidatingPolicy, ImageValidatingPolicy, MutatingPolicy, GeneratingPolicy, DeletingPolicy, with real-world examples of how you can use them to solve complex security, automation, and governance issues. The talk will end by showcasing how you can combine the usage of these policy types, for advanced platform engineering solutions. **2️⃣ Kyverno más allá de la validación: automatización con mutación y generación de recursos**, [Javier Dompablo](https://www.linkedin.com/in/javier-d-62a7b824b) - *Expert Platform Engineer and Product Security en [Schwarz Digits](https://www.linkedin.com/company/schwarz-digits-spain/)* (Talk in Spanish 🇪🇸) En esta sesión exploraremos dos de las capacidades más potentes de Kyverno: la mutación y la generación de recursos. Veremos cómo automatizar las configuraciones, aplicar de forma transparente los estándares de la plataforma a los equipos de desarrollo y reducir la carga operativa mediante la creación y la modificación automáticas de recursos en Kubernetes. A través de ejemplos prácticos, descubriremos cómo implementar políticas que mejoran la consistencia, la seguridad y la gobernanza de los clústeres sin necesidad de modificar las aplicaciones. See you there 👋

Some of it runs during install, some in CI, some inside the editor, and some with access to real credentials. This talk explains how recent supply-chain attacks abused that trust and what developers can do to reduce risk without stopping delivery. **19:20 Under the hood: How V8 powers your JS apps (and why you should care)** Speaker: [Gwyneth Rose](https://www.linkedin.com/in/gwyneth-rose/), Senior Engineer at Lodgify You've transpiled your JavaScript, minified it, chunked it, and sent it to your CDN. But what happens when the code actually hits the browser? In this talk, we'll walk through the workings of V8, the JavaScript engine that powers Chromium-based browsers and Node.js. We'll focus on its JIT (just-in-time) compiler, how it learns about your code at runtime, and how it optimizes for performance as you use a web app. We'll also go over concrete techniques to make the JIT compiler's job easier, helping you stay in V8's fastest execution path. **19:50: Drinks and networking!** **20:45 Meetup finished** Would you like to talk at the next meetup?

**🔎The session:** AI is already part of how we work, but most people are still using it as a chat or an autocomplete tool. The next step is moving from asking for help to letting AI actually do parts of the work for you. **That is where agents come in**. In this session, we explore **how to build and use AI agents in a practical way using tools like GitHub Copilot, Agent Mode, MCP, and reusable skills**. The focus is not on complex architectures, but on what is useful in real day-to-day work. We walk you through **what an AI agent is** and why it makes sense to use one instead of just prompts or simple automations. You will see how agents can reason, plan, and execute tasks across multiple steps, and how to apply patterns that already work in production. We also look at **how this fits into your existing workflow**, especially in environments like VS Code, and **how agents can connect to real systems and data**. Real examples will show how to automate documentation, interact with data platforms such as Microsoft Fabric, and create reusable workflows that save time. The session also **covers common mistakes**, including overcomplicating solutions with too many agents, and how to keep things simple, controlled, and maintainable. 🎯**The goal is to give you a clear and practical understanding so you can start using agents in your own work without overengineering.** 👩‍💻**This session is for you if:** * you are a developer working with code on a daily basis * you use tools like VS Code, GitHub, or similar environments * you are an engineer interested in improving productivity using AI beyond autocomplete * you want to explore how to integrate AI agents into real workflows -No prior experience with AI agents is required -Basic understanding of development workflows is enough 📋**Agenda** 🙋18:00 Registration & Welcome **🗣️18:30** Session and Q&A 🌮19:30 Drinks & Bites We look forward to this inspiring evening together! 🤩

Close to twenty years of production platforms, infrastructure, distributed systems, developer tooling, and the organisational structures around them. My background is in software engineering and architecture, but most of my work has lived where product requirements, developer tooling, infrastructure, delivery process, and team structure all meet. I build the systems around the software as much as the software itself. I have run full technology functions end-to-end: development, architecture, DevOps, delivery, hiring, vendor strategy, and operational structure. A lot of my career has been spent taking environments that are unstable, fragmented, or afraid to ship, and turning them into organisations that can move quickly without collapsing under their own weight. I still work hands-on every day. I write code, work in infrastructure, and stay close to the actual problems instead of managing them from a distance. *** * **Title: DevOps Horror Stories Vol. 1** * **Speaker**: **[Vicent Soria](https://www.linkedin.com/in/vicentsoria/)** \- Fractional Infrastructure Engineer @ [techabreath.com](https://techabreath.com/) * **Duration**: 30-45 mins * **About**: I work with management and technical teams to connect strategy with execution. My goal is to transform technology from an obstacle into a business driver. I act as a fractional CTO, DevOps engineer, or technology consultant, depending on each client's needs at any given time. I provide a practical and strategic perspective, helping to make impactful technology decisions: those that accelerate projects, improve processes, and align technology with business objectives. \-\-\-\- 🔑 **Important Access Note** Our host requires the attendees to provide their ID to grant us access to their offices. **Do not forget to fill in the "NIF - NIE - Passport" field** when registering!

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** *July Meeting - Lightning Talks!* Lightning talks are very short presentations on a topic of your choice (must be related to .NET). Talks should be 15-20 minutes in length and include minimal slides and quick demo (no live coding please). There will be 6 slots available! First come, first serve! **YouTube Link** TBD

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
