**„Květnový sraz, kde se řeší novinky i přístupnost s Claude Code!"** Jaro je v plném proudu a my se opět scházíme v pivovaru Lajka. Tentokrát na vás čekají čerstvé novinky ze světa frontendu a přednáška o tom, jak propojit Obsidian s Claude Code pro web accessibility. Vezměte dobrou náladu a přijďte! **Budeme se scházet postupně od 18:00 a od 18:30 máme na programu:** * 📰 Nowwwinky – Tomáš Kout * ♿ Obsidian + Claude Code = web accessibility **–** Petr Koláček * 🎲 Risk{f}uj! **Nowwwinky 📰 – Tomáš Kout** Co je nového ve světě frontendu? Tomáš pro vás jako vždy vybral to nejzajímavější, co se od posledního srazu událo. **Obsidian + Claude Code = web accessibility 👩🏽‍🦯 – Petr Koláček** Díky AI můžeme dnes poměrně lehce překonávat technologické bariéry a stavět aplikace, které bychom dříve sami nesvedli. Je to ale vždycky potřeba? Nejdeme často s kanónem na vrabce? Jak postavit nástroj, který nám pomůže s webovou přístupností pouze pomocí aplikací a služeb, které máme dávno k dispozici. *Petr je frontendový vývojář s více než 20letou praxí. Dlouhodobě se specializuje na CSS, webové UI, tvorbu design systémů a v posledních letech i na webovou přístupnost.* **„Risk{f}uj!" 🎲** Čeká nás další kolo oblíbené vědomostní soutěže na frontendová témata. Sestavte si tým a porovnejte svoje znalosti s ostatními soutěžícími. Těšíme se na vás v pivovaru! 🍻✨

Hello Gophers, Welcome back for another year of Go talks and networking! Would your company like to host our meetup? Let us know! If you'd like to give a talk - submit your proposals here: http://goo.gl/forms/54YvJT223F All talk formats work: short talks (5-10 min) as well as regular length (25 min). If you have more ideas - talk to us at the Gophers slack: https://invite.slack.gobridge.org/ in the #berlin channel, and follow us on twitter: https://twitter.com/gdgberlingo **Speakers**: *Simon Schulte* is a Tech Lead with nearly a decade of experience building scalable backend systems across fast-paced product companies. With a background in business informatics and a passion for Golang, cloud infrastructure, and DevOps, he has spent his career solving complex engineering challenges. He is particularly excited about leveraging AI and LLM workflows to eliminate the tedious, repetitive work that slows developers down — think tech debt, boilerplate, and documentation — so engineers can spend their energy on what actually moves the needle. For Simon, AI isn't about replacing developers; it's about giving them back their time. *Daniel Peralta Madriz* is a backend engineer from Costa Rica with around 6 years of experience working with Golang, although, sadly, he's been spending most of his time lately working with Node.js :(. He is interested in distributed systems, scalability, and developer experience, and is currently experimenting with how to leverage LLMs to safely and autonomously execute repetitive tasks. *Michael Morgen* is a Platform/infra engineer by day, runtime and network optimizations by night. Join in person at: **Talon.One** Talon.One is the incentives engine behind 300 of the world’s most-loved brands, unifying loyalty and promotions on a single flexible platform. Their customers run millions of real-time incentive decisions across markets, channels, and use [cases.As](http://cases.as/) incentives become more strategic than ever, they are continuing to raise the bar for what businesses can build and how fast they can build it Wiener Str. 10, 10999 Berlin https://maps.app.goo.gl/8eMjgWes1E4TBA3c7 or virtually at: https://www.youtube.com/live/qh__TQ1bMF0?is=hw21pk0ZE3HGyaaT *** Agenda 10:49 PM: Networking Networking over drinks and food 7:30 PM: Welcome Welcome words from the organizers 7:35 PM: Talk 1: Go-ing Against the Chaos: Deterministic LLM Workflows / Daniel Peralta Madriz (Backend developer) & Simon Schulte (Techlead of Webhooks and Notifications) @ Talon.One LLMs are powerful, but “it works most of the time” isn’t good enough for production. In this talk, we’ll walk through how to design deterministic workflows around non-deterministic models using Go. From structured iteration loops to validation steps and guardrails, you’ll learn how to move beyond prompting and start engineering reliable LLM-powered systems 8:10 PM: Announcements and break Announcements, HR lost & found, open mic 8:30 PM: Talk 2: About Go Memory Allocator / Michael Morgen, Platform/infra engineer @ Mirantis A short talk about how Go gives memory to your program. We will look at the main allocator parts, why small allocations are usually fast, when Go asks the OS for more memory, and a couple of simple examples where this knowledge helps performance. 9:05 PM: Networking Networking over drinks and food *** Hosted By Natalie Pistunovich, Organizer Ole Bulbuk, Organizer Tim Scheuermann, Organizer Anderson Queiroz, Organizer Complete your event RSVP here: https://gdg.community.dev/events/details/google-gdg-berlin-golang-presents-hybrid-may-golang-meetup-1/.

**Liebe Gophers,** am 13.Mai geht es bei uns um eines der wichtigsten Patterns in verteilten Systemen: das **Transactional Saga Pattern**. Wer mit Microservices arbeitet, kennt das Problem – eine Bestellung aufgeben klingt einfach, aber dahinter stecken Payment Service, Inventory Service, Shipping Service... und jeder hat seine eigene Datenbank. Was passiert, wenn mittendrin etwas schiefläuft? Klassische ACID-Transaktionen funktionieren hier nicht. Sagas schon. Unser Speaker Mark Borukhov zeigt, wie das Saga Pattern funktioniert – mit echtem Go-Code, einem E-Commerce-Beispiel und Live-Demo. **Was euch erwartet:** * Warum verteilte Transaktionen ein echtes Problem sind * Saga Pattern: Konzept, Choreography vs. Orchestration * Implementierung in Go – Schritt für Schritt * Pitfalls, Lessons Learned & Q&A Das Event richtet sich an alle – von Go-Einsteigern bis zu erfahrenen Entwicklern. Auch wer Go nicht kennt, aber Microservices baut oder Patterns liebt, ist herzlich willkommen. **Der Vortrag wird auf Deutsch gehalten.** Wir treffen uns um 18 Uhr bei [lynqtech](https://www.lynq.tech/). Mit dem Vortrag starten wir um 18:30 Uhr. Danach wollen wir über Technologien und Erfahrungen plaudern, voneinander lernen, Kontakte knüpfen und einfach eine tolle Zeit miteinander verbringen. Wir freuen uns auf euch! 🚀 *Mark & Anna*

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!
