*Nem a framework a nehéz, hanem az emberek* Egy transzformáció megvisel minden szervezetben dolgozót -pozíciótól függetlenül-. A csapattagok felé számtalan új elvárást kommunikálnak, a felsővezetők hirtelen elkezdenek magasabb szinten tervezni. De mi van a középvezetőkkel? Gyakorlatilag ők lesznek a "transzformációs belső tolmácsok" egyikei. Elvárásokat támasztanak feléjük. De vajon a segítséget is megkapják ezekhez? Célunk, hogy gyakorlati szituációkon keresztül bemutassuk, hogy mi milyen kihívásokkal találkoztunk, és milyen megoldásokkal próbálkoztunk. Pláne, amik működnek... :) [Horányi Emese](https://www.linkedin.com/in/emese-horanyi/), az Uniqa agilis coach-a, perspektívikus coach alkalmazotti szemmel, míg [Spánn Richárd](https://www.linkedin.com/in/rich%C3%A1rd-sp%C3%A1nn-3a56317b/), transzformációs tanácsadóként, külsős szemmel világít rá a lehetőségekre. \-\-\-\- Please note that this event is for Hungarian speakers only.

Az AI most már nem csak külső chatbotként jelenik meg a fejlesztésben, hanem az Oracle APEX világába is egyre mélyebben beépül. Ezen a meetupon gyakorlati példákon keresztül nézzük meg, mit jelent ez APEX fejlesztőknek, PL/SQL fejlesztőknek és vállalati alkalmazásokat építő csapatoknak. Az új verzió fókuszában az **AI-támogatott fejlesztés**, az automatizálhatóság és a modern fejlesztői élmény áll. A 26.1 legfontosabb újdonságai közé tartozik az **APEXlang**, amely olvashatóbb, fejlesztők és AI-eszközök számára is könnyebben értelmezhető alkalmazásleírást ad. Megjelent az **AI Interactive Reports**, amely természetes nyelvi támogatást hoz a riportolásba. Szintén fontos újdonság az **AI Agent Tools**, amely biztonságosabb és kontrolláltabb AI-alapú megoldások építését teszi lehetővé. Beszélünk a **Codex** APEX fejlesztésben való használatáról, az **OpenAI** integrációs lehetőségekről, valamint bemutatjuk azt is, hogyan építhető **projekt szintű chatbot** saját adatok és dokumentumok alapján. Célunk az Oracle Application Express népszerűsítése, a fejlesztői közösség erősítése és olyan gyakorlati megoldások bemutatása, amelyek valódi ügyféligényekre adhatnak választ. Ha érdekel az APEX, a low-code fejlesztés és az AI gyakorlati alkalmazása, regisztrálj minél előbb, mert a helyek csak korlátozottan állnak rendelkezésre. A rendezvény ingyenes, de regisztrációhoz kötött.

In the last DevBP meetup before the summer break, we will venture to the world of **Continuous Delivery**, exploring the craft of shipping software safely and continuously — from the practices that keep your releases boring, to the hard-won lessons of building the infrastructure behind a feature toggle. \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- **Continuous Delivery Never Died. It Became a Harness.** with [András Fincza (Draven) - XUND](https://www.linkedin.com/in/andrasfincza/) The PR-centered pipeline was already buckling under big batches, delayed feedback, and overloaded reviewers. Agents just turned up the volume. But the discipline that made CD work in 2015: trunk-based development, fast feedback, sociable testing, feature flags, quality gates. These matter more in 2026, not less. This talk is about what to keep from the old playbook, what to upgrade, and what to stop pretending works. **Building a Feature Flag service** with [Zoltán Dávid - ConfigCat](https://www.linkedin.com/in/zoltan-david/) Everyone knows what a feature flag is. Far fewer know what it takes to build and run a feature flag service at scale. In this talk, we'll go behind the scenes of ConfigCat: the technical decisions, the scaling surprises, and the business lessons that came from serving billions of feature flag evaluations. No introductions to feature flagging, just honest insights from years of building a product in a space where reliability isn't optional. \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- \-\-\- This English-language event will be held at the **Shapr3D office**, where we'll provide snacks and drinks to fuel conversations. Arrival is from 17:30, the presentations start at 18:00. You can also find the recordings of previous events on the [@DevBPMeetup YouTube channel](https://www.youtube.com/@DevBPMeetup).

Join the next Budapest Quant Group meetup for an exciting presentation by **Gábor Vigh, Director at MQA, Citi**, on cutting-edge machine learning methods in quantitative finance. The event concludes with networking. **Abstract:** Accurate and efficient calibration of equity volatility surfaces is fundamental to equity derivative pricing. When markets quote only American option prices, this task becomes significantly more complex. We present a neural network-based approach that overcomes these challenges, delivering calibration results while reducing the computational burden of conventional approaches. **Mandatory registration:** please send a mail to the following address: kinga.doktor@citi.com, with the following details: * name * company * job title **Agenda** * 18:30-19:00 Reception.

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

A session on using Claude Code, Anthropic's AI coding agent, in real Unity development. We'll cover what coding agents are, where Claude Code fits, and how to apply it to an actual game project. The format is presentation-style, with live demos and time for questions throughout. After brief scene-setting on coding agents and what makes Claude Code distinct, we'll go problem-driven: demoing it live on a released Unity game and introducing each feature as a solution to a problem we hit. What to Expect: * An intro to coding agents and where Claude Code fits * A live demo on a real Unity project * Key features as solutions to real problems: 𝖢𝖫𝖠𝖴𝖣𝖤.𝗆𝖽, context management, hooks, skills, subagents, and MCP * Unity-specific pain points, including Domain Reload and MCP caveats * Putting it together All experience levels welcome.
