Information Science

Speaker: **Luka Karlić** Title: **My first anniversary with Claude Code - am I still in the honeymoon phase?** In this talk, Luka will take us through his first year of (power)using Claude Code - what worked, what didn’t. How does he keep learning instead of just producing? What about critical thinking? Expect a fair amount of rambling about harness, scaffolding, memory, even brain-atrophy. Last but not least - why, to him, this is both the easiest and the hardest time to be an engineer. \-\-\-\-\-\-\-\- Drinks and friendly discussion afterwards at [Buzz Bar](https://maps.app.goo.gl/e8dCmPL5ZBhzua717) 🍻🍷🥤☕️

Nakon duže pauze, za UXR Zagreb meetup#5 puta udružujemo snage s[ Vibe Coders Croatia](https://meetup.com/vibe-coders-croatia). Dvije zajednice koje obično sjede na suprotnim krajevima proizvoda — mi koji razgovaramo s korisnicima i oni koji ga deliveraju — u istoj prostoriji. Ono što nas spaja (kao i ostatak software development svijeta) je AI. Na ovom meetupu pričat ćemo o tome kako AI (1) mijenja i proširuje rolu researchera i (2) mijenja pristup tehničkoj dokumentaciji. \*\*\* **Raspored** 18:00 - Uvod u temu 👋 18:15 - 19:30 - Predavanja + diskusija💡 19:30 - XX:XX - Networking + drinks 🧋 \*\*\* **Sažeci predavanja** **From Insights to Infrastructure: Expanding UXR Impact with AI** AI changes how everything in software development works, including research. This talk walks through some of my applications of AI across the research process, from organizing participant recruitment and data analysis, to bridging the gap between insight and delivery. It makes the case that researchers now have the opportunity to shift from *delivering insights* to *owning research infrastructure*. **[Filip Užarević](https://www.linkedin.com/in/filip-uzarevic-b4b87584/) -** User Researcher \- \- \- \- **Is Documentation Dead or More Alive Than Ever?** AI generates docs in seconds — but the code they describe changes just as fast, which makes stale documentation a \*bigger\* problem, not a smaller one. This talk explores why the AI era demands a different approach to documentation, and looks at Tesso, a tool that connects documentation to the actual code written by AI and humans alike — so the docs and the codebase stop drifting apart. **[Danijel Buhin](https://www.linkedin.com/in/danijelbuhin/) -** Software Engineer. \*\*\* **Napomena -** ima cca 45 sjedećih mjesta. First come first served :) Oba predavanja održat će se na hrvatskom. \*\*\* Thanks to Reactor for providing us with space and drinks \*\*\*

Join us for **BipTalks Engineering Meetup**, where we’ll explore how AI technologies perform once they leave the sandbox and enter real-world systems, through two first-hand talks. From the MCP protocol that can turn your existing API into an agentic service, to using LLMs effectively to build tools that solve problems reliably and efficiently — both talks offer concrete, actionable knowledge drawn from production experience. 💡 **What to expect:** * **Real-world insights from production** — Both talks are grounded in hands-on experience. No theory for theory's sake — only what actually worked (and what didn't). * **Concrete tools you can use right away** — Learn how to turn an existing API into an MCP server and how to use LLMs to build solutions that work every time. * **A clearer view of software development with fast-evolving protocols** — Understand how to make architectural decisions in an environment where standards and tools shift week to week. 🎤 **Speaker: Filip Pankretić, Junior Software Engineer @ Infobip** Filip is a Junior Software Engineer at Infobip with a deep passion for machine learning. He works with voice models — teaching them how to listen, and sometimes how to respond. He helped open Infobip's platform to AI agents worldwide using MCPs, giving them communication superpowers. 🎤 **Speaker: Filip Srnec, Principal Engineer @ Infobip** Mathematician, engineer, father, and husband. At Infobip, Filip currently leads the MCP initiative with the goal of opening the communications platform to the agentic world. He has worked on challenging projects across diverse areas — from scientific computing to scalable distributed systems and API governance. He has spoken at conferences including Devoxx UK and Infobip Shift, and teaches at the Department of Mathematics at the Faculty of Science as an external associate. After the official part of the program, stay with us for **great conversations and refreshments** 🍕🥤 🎟️The event is **free**, but the spots are limited so please register here: [Bip Talks Zagreb - Infobip](https://www.infobip.com/hr/c/biptalks-engineering-meetup-zagreb)

Meetup #2 for **Vibe Coders Croatia** — this time we're joining forces with **[UXR Zagreb](https://www.meetup.com/ux-research-zg/)**. Two communities that usually sit on opposite ends of the product — the people who *talk to users* and the people who *ship to them* — in one room for a night. The bet: vibe coders move fast and build, UX researchers know *what's actually worth building and why*. Put them together and you get a sharper loop — research that ships, and shipping that's grounded in real user evidence. Two talks, both in Croatian, one from each side of that table, then the hallway conversations where the next side project (and your next user interview) starts. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 📣 **From Insights to Infrastructure: Expanding UXR Impact with AI** AI changes how everything in software development works — including research.

**Register here: [https://events.3nf.hr/Seminar.aspx?eid=adc0dd14-ea08-4c03-8eff-bb55d7bc4fd0](https://events.3nf.hr/Seminar.aspx?eid=adc0dd14-ea08-4c03-8eff-bb55d7bc4fd0)** This one-day seminar is intended for data and analytics professionals who want to understand how to design, implement, and use Microsoft Fabric effectively. It provides a practical, end-to-end overview of Fabric’s key components, including OneLake, data ingestion and transformation options, lakehouse and warehouse choices, and the evolving role of Power BI within Fabric. Participants will also gain insight into AI capabilities, security, CI/CD, and licensing, and will apply their knowledge through hands-on labs to build a complete analytics solution.

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.

Join the Columbus AI community for a special event. **Battle of the Personal Agents** is your chance to see what people are actually building with AI agents and personal automation systems. Whether you’re running OpenClaw, Hermes, or a completely custom solution, bring your agent and show the community how it works. We’re interested in real-world implementations: the problems your agent solves, how you use it day-to-day, how it’s hosted and managed, how you built it, and why you’ve chosen to keep using it. Live demonstrations are encouraged, so be prepared to show your code, architecture, workflows, and your agent performing real tasks. This is less about polished presentations and more about sharing practical experience, comparing approaches, and learning from one another. If you’d like to present, please contact Chris Slee (via meetup) before the event so we can allocate enough time for everyone’s demonstrations. Come ready to show what you’ve built, discover what others are doing, and maybe find a few ideas worth taking home. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
