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) 🍻🍷🥤☕️

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)

Open Heart Meditation Sessions with Amrita Rani (Live in-person and online on selected Thursdays via Zoom) You are warmly invited to join the Open Heart Meditation Sessions with Amrita Rani. These sessions are created both for beginners and seasoned practitioners who wish to deepen their meditation practice, stabilize awakening, and walk the path of enlightenment with guidance and support. Whether you are new or experienced, each gathering offers a grounded structure to help you build consistency in daily practice and grow in confidence on your spiritual path. At the heart of Open Heart teachings is direct recognition. Through the Two-Part Formula and precise meditative guidance, you are supported in shifting from self-based mode into selfless awareness, again and again, until cessation of self-based suffering takes place. A central and deeply transformative practice in Open Heart is guru yoga. Through guru yoga, the practitioner directly connects with awakened awareness through devotion, transmission, and experiential recognition. With the help of this profound method, one recognizes their true selfless ease, the natural, effortless state beyond space and time. Alongside guru yoga, the sessions include insight meditation (Vipashyana), tantric methods, dynamic concentration, trauma-healing techniques, and foundational practices such as Bodhicitta prayers. Each session includes guided meditation, space for questions, reflection, and personal support. Rani’s meditation sessions are held live on Zoom on selected Thursdays from 18:30 to 20:00 (CET). Recordings may be available for continued integration and practice on her YouTube channel, The Sweetness of Enlightenment. Participation fee: 15 € per session Please make your payment in advance via PayPal before joining, to Rani’s PayPal account: kaisaeskeli@gmail.com Upcoming Thursday Sessions for Summer Season: 14.5.2026 at 18:30–20:00 (CET) 4.6.2026 at 18:30–20:00 (CET) 11.6.2026 at 18:30–20:00 (CET) 18.6.2026 at 18:30–20:00 (CET) 25.6.2026 at 18:30–20:00 (CET) 2.7.2026 at 18:30–20:00 (CET) 9.7.2026 at 18:30–20:00 (CET) 23.7.2026 at 18:30–20:00 (CET) 30.7.2026 at 18:30–20:00 (CET) Zoom link for all sessions: https://us02web.zoom.us/j/89766267672 Welcome all!

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. This talk walks through applications of AI across the research process, from organizing recruitment and analysis to bridging insight and delivery, and makes the case that researchers now have the opportunity to shift from *delivering insights* to *owning research infrastructure*. **Filip Užarević**, User Researcher * [LinkedIn](https://www.linkedin.com/in/filip-uzarevic-b4b87584/) \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 📣 **Is Documentation Dead or More Alive Than Ever?** AI generates docs in seconds, but the code those docs 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**, Software Engineer * [LinkedIn](https://linkedin.com/in/danijelbuhin) \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- 🗣️ Both talks will be held in Croatian. 📹 Not recorded or streamed this time — you have to be in the room. 🪑 There are a limited number of seats, first come, first served. 📍**Location**: **Zadarska ulica 80, 6th floor — Reactor Studio.** Use the main entrance on the right side of the building. If you're driving, the Lidl parking lot nearby is your best bet, or grab any free spot around the buildings.

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
