This event will be held in English 🇬🇧

***Talks & Speakers:***
**🔈 Talk 1 - Building Reliable Customer Experiences, The Pipedrive SRE Journey 🗺️**

* *[Nelson Gomes](https://www.linkedin.com/in/nelsonricardogomes/) \- Senior Software Engineer \- [Pipedrive](https://www.linkedin.com/company/pipedrive/)*
* *Pipedrive has an unique infrastructure, hundreds of thousands of customers, many more users, thousands of databases, serves billions of requests per month, executes billions of queries per month, a few years ago it was rare to have customers with a hundred users, now we have plenty of customers with hundreds of users. A tale about the challenges SRE team faced while handling such a massive infrastructure as the one Pipedrive has, solutions implemented and results obtained over the course of recent years and the impact SRE has made.*

***🔈 Talk 2 - Learnings and turnings of RBAC at Scale in Grafana* 👀**

* *[Eric Leijonmarck](https://www.linkedin.com/in/eleijonmarck/) \- Software Engineer \- [Grafana Labs](https://www.linkedin.com/company/grafana-labs/)*
* This talk is going to talk about what "access" actually means in the world of identity and access management (IAM). We will share our experience with setting up RBAC in Grafana – the good, the bad, and why we had to rethink our approach. Other big players like Netflix and Google design their access models. Basically, it's a real-world look at our journey with access and some cool ideas we've picked up along the way.

**🔈 Talk 3 - Handling Technical Challenges of Security Scanning in CI/CD 🧪**

* *[Tiago Mendo](https://www.linkedin.com/in/tiagomendo/) \- Director of Product Strategy \- [Snyk](https://www.linkedin.com/company/snyk/)*
* Have you ever tried to add a web application security scanner to a CI/CD pipeline? I intend to draw attention to some of the challenges that teams experience when trying to automate security tests. The objective is to make the audience aware of these problems so that they can solve them as soon as possible, increasing the success of the tests, and the adoption by the teams, which in the end, will lead to greater security for the organization.

We're thrilled to invite you to our next 🌸 Grafana & Friends Amsterdam Meetup 🌸

Many thanks to our good friends at [HCS Company](https://www.hcs-company.com/), who have kindly offered to host us at their Amsterdam office and share their experience 🫶

📕 **Agenda**

**17:30** Open doors.
**18:00** Food & Drinks
**18:30** Meetup starts: talk & workshop

🗣️ **Talk**
**Monitoring and Managing Edge Devices at Scale with Grafana: The ProRail Approach - [Ho Yeung](https://www.linkedin.com/in/cshy/)**

This talk presents how ProRail has implemented a scalable and efficient monitoring solution for its IOT2050 edge devices using Grafana and containerized services. Attendees will learn how system metrics, Docker container statuses, and MQTT data are collected from edge devices and visualized in real-time dashboards, enabling both operational oversight and historical analysis. The session covers the integration of tools such as Grafana Agent, Alloy, Node Exporter, Mosquitto, and Node-RED—deployed through Portainer—to build a resilient monitoring infrastructure. We’ll also showcase interactive Grafana dashboards, including a nationwide map of edge devices, and explain how alerting mechanisms help detect issues early and reduce downtime. This session is ideal for observability engineers, systems specialists, and anyone interested in edge monitoring and infrastructure visibility at scale.

**🎙️ Ho Yeung** is currently working at ProRail, focusing on the development of an observability platform designed to streamline the collection and processing of measurement data. His work involves integrating diverse measurement devices into a system, automating data validation processes, and leading the visualization of data using Grafana. He collaborates with end-users and technical teams to ensure effective data presentation and decision-making, configuring Grafana in a Kubernetes environment.

🛠️ **Workshop**
**Logs, Metrics, Traces, and Mayhem: An Interactive Observability Adventure** - **[Imma Valls](https://www.linkedin.com/in/imma-valls/)**

This is a hands-on introductory session on observability. Through an engaging text-based adventure, you'll learn to diagnose and resolve issues in your systems. This workshop covers essential observability tools —metrics, logs, and traces — and shows how to leverage them effectively for real-world troubleshooting and insights in your application.
Bring your laptop for this session. Docker and git or a browser to run this on a killercoda playground are prerequisites. You can also work in pairs.

**🎙️ Imma Valls** is a Staff Developer Advocate at Grafana Labs. Imma enjoys automating stuff, and anything that helps get apps from development to production. She also loves sharing with local communities and helping them connect and thrive. She co-organizes Grafana’s meetups in Barcelona and Madrid, Cloud Native Barcelona meetups, and Software Crafters Barcelona. She also volunteers as a coach and board member at the TechFems Barcelona community and collaborates with Technovation Girls as a Judge.

🏢 **Location**
**HCS Company**: Anthony Fokkerweg 61\, Amsterdam \| https://maps\.app\.goo\.gl/LPMZKBzB7MutGrZb6\.
The HCS Company office is easily accessible by both car and public transport. You can park your car on their premises; ample parking is beyond the barrier. If you come by public transport, you can get off at the Henk Sneevlietweg metro station; from there, it is a 10-minute walk.
