Lean Product Management

DubJUG 265, our live in-person event, presents Professor Ž (aka Željko Kozina!) Hear why Netflix dumped REST in favour of GraphQL and explore how memory management improves performance, the different parts of Java memory and the various garbage collectors. OFFICIAL BOOKING >>>>> https://ti.to/dublin-java-user-group/265-zeljko-kozina ## **Talk 1:** Netflix dropped REST, but should you? Last year, Netflix announced that it was dropping REST completely in favour of GraphQL. It is undoubtedly one of the popular kids on the Development playground right now. GraphQL is a new way to build APIs, one that's easier, faster, better, and more flexible than the old RESTful API system, or at least that's the promise. In this session, a REST developers' Assessment of Spring GraphQL, Željko will cover the basics of Spring GraphQL, explore its strengths and weaknesses, and determine whether it is a better option for your company than a conventional REST API. ## **Talk 2:** Trash Talk - Optimising Java Garbage Collection Understanding how Java organises memory is important for every Java professional, but this particular topic is a common knowledge gap for many software professionals. With the help of Željko, this talk explores how memory management can help you improve performance effectively, helping you understand the different parts of Java memory and the various garbage collectors so you can select your preferred one.

Vision Language Models (VLMs) such as LLaVA, Qwen-VL, Nemotron VL and GPT-4o have unlocked a new era in AI where language and sight converge into a single reasoning system. These models can describe images, answer visual questions, read documents, and interpret charts — but their true power emerges when you fine-tune them on domain-specific data, teaching them to see and reason about the visual world that matters to you. In this hands-on session, we walk through the full fine-tuning pipeline for vision-language models. We begin by understanding how these architectures work — how a visual encoder like CLIP or SigLIP is coupled with a large language model through a projection layer, and how the interplay between image tokens and text tokens enables multimodal reasoning. We then move into the practical side: preparing image-text datasets, choosing the right fine-tuning strategy (full fine-tuning vs. LoRA vs. QLoRA), configuring training with frameworks like Hugging Face Transformers and PEFT, and evaluating results on real-world benchmarks. We will also discuss when and why fine-tuning a VLM is the right approach compared to alternatives like prompt engineering or retrieval-augmented generation, and how to avoid common pitfalls such as catastrophic forgetting, overfitting on small visual datasets, and misaligned image-text pairs. Bring your laptop, your curiosity, and — if you have one — a dataset you would like to try. By the end of the session you will have a clear, reproducible workflow for adapting any open-source vision-language model to a custom task. \*\*📅 Open to all levels — no prerequisites, just curiosity.\*\*

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!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. 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.

This meetup is a beginner-friendly session introducing version control for Unity projects, with a look at three common tools: Git, Perforce, and Unity Version Control. The goal is to help you understand what version control is, why it matters for Unity development, and what options are out there. The format will likely be presentation-style, with live demos and time for questions throughout. You'll see each tool in action and learn how they fit into a Unity workflow. What to Expect: * An introduction to version control and why it's essential for Unity projects * An overview of Git, Perforce, and Unity Version Control * Demos of each tool in a Unity workflow * Tips for getting started * No prior version control experience required * Resources for continued learning All experience levels are welcome. Whether you're new to version control or already using one of these tools, this session will help you understand what each one offers. Food and drinks provided. Join us to learn more about version control options for Unity.

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
