A special edition meetup with a very special guest! International speaker Daniel Afonso will talk about the Framework wars and what he learned from them! Don't miss out! 🚀 ────────── **18:30: Welcome** **18:45 Intro by Host Neciu Dan** **19:00 React-Driven Development: Career Lessons from the Framework Wars** Speaker: Daniel Afonso, Senior Developer Advocate at PagerDuty "No one uses what I built!" "Why can't I get support to do this?" "I don't even know why we're using that?" "Why am I always the one doing everything?" Sound familiar? The truth is, friction is ever-present in our careers — in our influence, processes, relationships, and even the code we ship. But we're rarely taught how to handle it. Here's the fun fact: React's history is full of lessons in dealing with friction. From the early skepticism around JSX and the Virtual DOM to the chaos of Server Components, the React team has navigated many friction points you'll face: skeptical stakeholders, unclear messaging, delayed initiatives, and the challenge of getting buy-in. So let's recap the highlights since its birth to the latest release, understand what React got right (and wrong), and extract practical takeaways you can apply to your career, team, and developer experience initiatives. Whether you're leading a team, building internal tools, or advocating for a technical decision, you'll leave with concrete strategies for driving change, building trust, and shipping initiatives that actually get adopted. **20:00: Drinks and networking!** Do you want to talk at this meetup?

**Hello, fellow DevOps enthusiasts 🤓** On **May 7th**, we'll meet again for a couple of insightful talks, hosted by **[Dynatrace](https://www.dynatrace.com/)**! 📍**Location**: Avda Diagonal 211 \- 14th floor\, Torre Glòries\, Barcelona \| [https://maps.app.goo.gl/22q31ECkaW7BzDMD8](https://maps.app.goo.gl/22q31ECkaW7BzDMD8) \-\-\-\-\-\- 📅 **Agenda** * **18:30 - 18:40** Welcome from the hosts * **18:45 - 19:30** "The microservices kool-aid and what that means for SREs" * **19:30 - 20:15** "Observability in the AI-Native DevOps Age" * **20:15 - 21:00** Networking & Snacks \-\-\-\-\-\- **🎤 Talks & Speakers** * **Title: "The microservices kool-aid and what that means for SREs"** * **Speaker**: [Csaba Almási](https://www.linkedin.com/in/csaba-almasi/) - *Staff Platform Engineer at [Neonomics](https://www.neonomics.io/).* * **Duration**: 30-45 mins * **Abstract**: For years, the industry has treated microservices as the default architecture for any scaling project, but for SREs, this "Kool-Aid" often comes with a bitter aftertaste. This session moves past the hype to examine the true operational tax of service proliferation, specifically focusing on how fragmented architectures drive up observability costs and create silent performance bottlenecks through network overhead and resource contention. We will dive deep into the technical signals that reveal a "distributed monolith"—a system that shares the complexity of microservices but retains the rigid coupling of a legacy app—and provide a rubric for identifying when an architecture has become more of a liability than an asset. Beyond the theory, we’ll explore practical guidelines for determining when to actually decompose a monolith and, perhaps more importantly, when to move in the opposite direction. Using real-world examples from the field, we will walk through the architecture and design decisions behind both successful service extractions and strategic consolidations of over-engineered distributed systems. You’ll walk away with a framework for balancing technical depth with operational sanity, ensuring your architecture evolves based on performance data rather than industry trends. * **About**: Csaba Almási is a Staff Infrastructure Engineer at Neonomics, where he focuses on building reliable platforms and maximizing the business impact of observability. With extensive experience in SRE and distributed systems, he specializes in bridging the gap between technical architecture and operational efficiency in the fintech sector. \-\-\-\-\-\- * **Title: "Observability in the AI-Native DevOps Age"** * **Speaker**: [Andreas (Andi) Grabner](https://www.linkedin.com/in/grabnerandi/) - *CNCF Ambassador, Book Co-Author, and Fellow DevRel at [Dynatrace](https://www.dynatrace.com/)* * **Duration**: 30-45 mins * **Abstract**: *AI is here to stay!* *The question is: How to make it an efficient DevOps partner for the human to build, test and operate software?* The answer is simple: Just like humans, the AI can use observability to understand and optimize the impact of generated and deployed code and configuration. In this talk you learn the path through three important lessons on how observability as you know it is changing to become useful for the Human and the AI as we enter the AI-Native Age. **1.** **The Observability Primer**: “What’s different in observing an app, an AI or a workflow?" **2.** **The AI Delivery Lifecycle**: “How can my AI becomes better with observability?” **3\. Cost and Impact**: “How can we speed up while staying within budget?” You will walk away and know how to best apply open standards like OpenTelemetry and OpenLLMetry to get insights and optimize your own usage of AI. Whether its for coding, automation or to provide it as a business feature! * **About**: Andreas Grabner has 20+ years of experience as a software developer, tester, and architect, and is an advocate for high-performing cloud-scale applications. He is a CNCF ambassador, a contributor to the CNCF project keptn, a Co-Author of Platform Engineering for Architects, and a Fellow DevRel at Dynatrace. Andreas is also a regular contributor to the DevOps, Platform Engineering, and Cloud Native communities and a frequent speaker at technology conferences. In his spare time, you can most likely find him on one of the salsa dancefloors of the world! \-\-\-\-\-\- 🔑 **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, and do not forget to **bring your ID**!

Two weeks ago Yann LeCun and his team at New Yourk University published a paper http://yann.lecun.com/exdb/publis/pdf/lecun-06.pdf aimed to tackle a fundamental problem of AI -- world model, an obstacle that can keep us at the current level of LLM-s for potentialy centures, or can take us to singularity if it will be solved. To do this LeCun used EBM -- energy base models instead of classical probabilistic densities. We are planning to discuss energy based reasoning from mathematical point of view and also discuss connected technologies and their perspectives. Main article that we will discuss https://openreview.net/pdf?id=ZBj3Qp1bYg This is part of the scientific paper reading club. Presenter: Anier Velasco Sotmayor, teacher at Harbour Space Institute of Technology language of the meeting: English. Entrance donation: 15 eur

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!
