**Now that Claude Code is writing our software, what are you doing with all that free time?** Here's an idea: come spend it with us at the next Belgium NLP Meetup! Our next event will take us back to **BeCentral**, Brussels' prime digital campus, where we're hosted by our friends at Campfire AI. Go ahead and schedule that long Claude job for the evening of **May 5th**. Doors open at 7pm for pizza, talks are planned between 7.30pm and 9pm, and after that there's more time for networking and drinks. The first two talks of the evening are already confirmed. The final presentation will be added in the coming weeks. **Small, specialized, agentic – One Year of Fine-tuning Local Vision LLMs.** *Adriaan Lemmens & Ilia Breitburg (Klassif.AI)* Local LLMs are getting better each year. The smaller the model, the more impressive. While the big labs' closed models still win as generalists, we've been working on fine-tuning our own specialist for enterprise document processing on top of an open-weights base, adapted for use in our custom agent harness and for visual layout reasoning. Recent iterations come within spitting distance of much larger models at a fraction of the size and token usage. In this talk, we share why and how we did it, as well as what it means for how we build efficient agentic systems at Klassif.ai even with hosted models. **Why NLP is More Alive Than Ever in the Age of LLMs.** *Tomas Staelens & Jean-Charles Nadé (Campfire AI)* The hype surrounding Generative AI has led many to believe that traditional NLP is a thing of the past, but the reality on the ground is different. In this talk, Tomas and Charly dive into why "just prompting it" often fails in enterprise environments where cost and ROI are non-negotiable. They will showcase the synergy between NLP and LLMs and argue that the future belongs to a hybrid architecture. Finally, they will share practical patterns for using NLP as a guardrail and optimizer for AI workflows. **Building AI‑native agentic extraction for commercial leases: the grown‑up path** *Frederik Durant (Reavant)* The art of agentic engineering is transforming the software development life cycle at an unprecedented pace. In this new arms race, AI engineers, software architects, and DevOps practitioners are expected to deliver 10x the impact without compromising quality or accountability. In this talk, Frederik will candidly describe his human experience so far navigating this professional identity shift. Additionally, he will show how his company Reavant built an agentic extraction system for complex tenancy documents, and what this taught him about going truly AI‑native.

📢 PGConf Belgium 2026 is back! We’re happy to announce that PGConf Belgium will take place again this year on **Tuesday, May 5th**, at its usual venue: the **UCLL campus in Haasrode**. 🗓️ The preliminary schedule is already available: [http://pgconf.be/#schedule](http://pgconf.be/#schedule) 🎟️ Registration is **free of charge**, but seats are limited to **120 attendees**, so make sure to secure your spot early! ➡️ Register here (mandatory): [http://pgconf.be/#registration](http://pgconf.be/#registration) ⏳ Deadline: **April 28th** ⚠️ Please note: RSVPing on Meetup is appreciated to let others know you're attending, but it **does not count as registration** — you must register via the official link above. 🙏 A big thank you to **Wim Bertels** for organizing the event, and to **UCLL** for hosting!

Let's meet to write! Schedule : 18:00 - 18:30: Arrival & introduction tour. Share briefly with the group your project and the "goal of the day". 18:30 - 20:00 : Let's write! 20:00 : Closing tour. Did you achieve the "goal of the day" ? See you soon !

We do cycles of 4-6 weeks, with a progressive load, and a recovery week at the end of the cycle. Session: * 10 - 20’ warm up (easy run and drills) * Core session (ie. 6x5' - 2' recovery) * Cool down We run together during Warm-up, and cool down and tey to regroup during recovery time. Paces are not imposed (everyone runs at his/her own pace) given the intensity suggested. Notes: It's NOT required to have an activity tracker or smart watch to be able to follow the session, as I'll be giving signals with a whistle. Intervals training is not advised for total beginners. To have an idea, the average pace at the warm up is around 5'45"/km-6'15"/km so this pace should feel very comfortable ***Acknowledgement of member responsibility and release of liability.*** By signing up for this event, you agree to release the organizers from any responsibility and liability in all claims. As the participation is strictly voluntary and you freely choose to join, it is the responsibility of individuals participating to ensure that they are fit enough and have adequate coverage to protect themselves.

Come and join **your fellow peers** to have a good time **practicing** **writing code** to get better at writing code in your real jobs. We’ll start off with **koffiekoeken** and form pairs to do the Game of Life Code Kata. After 45 minutes we’ll delete all our code and talk about new insights you’ve gained. Then we’ll pair up with new people and do it all over again but with new constraints applied, like not using conditional expressions, or committing code on green within 2 minutes. At some point we’ll break for lunch and we’ll figure something out for dinner too. ## **What to bring?** This event is very hands-on and it’s always better to come prepared.

For centuries, the figure of the pirate has occupied a strange place in our imagination, both villain and folk hero, outlaw and symbol of freedom. From the swashbuckling adventures of Captain Jack Sparrow to the real-world exploits of Blackbeard, piracy has often been romanticized as a life unshackled from authority, where individuals carve their own destiny beyond the reach of states and laws. Beneath the mythology, however, lies a deeper philosophical question: what does it mean to live freely, and at what cost does that freedom come? Yet piracy is far from a relic of the past. In today’s world, the term stretches far beyond the high seas, reaching into the digital realm, where so-called “internet pirates” challenge the boundaries of ownership, access, and intellectual property. From peer-to-peer file sharing to the rise and fall of platforms like The Pirate Bay, the debate has evolved into a question of whether information should be free or protected. At the same time, accusations of “piracy” still surface in geopolitical conflicts, where the line between enforcement and overreach becomes increasingly blurred. Recent actions involving the seizure of vessels, particularly by powerful states like the United States, have reignited debates about legality, sovereignty, and moral authority on the high seas. When does the defense of order begin to resemble the very lawlessness it seeks to prevent? And who, ultimately, gets to define what piracy really is? This debate will follow a British Parliamentary format with eight debaters split into **four teams of two.** Participants who wish to speak are highly encouraged to bring a paper and pen. You are welcome to participate even if you have no prior debating experience. We aim for debates that are respectful, constructive, and welcoming: * **Respect ideas and people** Listen actively, stay quiet while others speak, and debate arguments, not identities or beliefs. * **Be concise and civil** Keep questions short and relevant; avoid hostility, hate speech, or discrimination. * **Respect boundaries and time** No unwanted advances or suggestive behavior; arrive on time to avoid disrupting the debate. * **Follow moderators** They guide the discussion and ensure fairness.

***Harbour*** is a worker placement game where players move their worker from building to building, collecting and trading Fish, Livestock, Wood, and Stone; and cashing those resources in to purchase buildings (which are the worker placement spots) from the central pool. Once a building is purchased, it is replaced from the deck, and the central pool is a small subset of the deck, and is therefore different every game.

If none, that's cool too. Round 3: * Job opportunities you're hiring for OR announce that you are looking for one. If none, that's cool. After the introduction circle, everything is self-organized! Feel free to work alone, pair up, attend one of our workshops/presentations, or mingle!

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!
