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/.

Join us for a two-day Botanical Watercolour experience, where we’ll step out of the studio and into two *almost hidden* gardens in Friedrichshain to paint plants directly from life 🌿 Over two days, we’ll meet in two different, *almost hidden* gardens in Friedrichshain—quiet green corners of the city where we can slow down, observe, and paint plants directly from life. Think wild flowers, textured leaves, unexpected shapes, shifting light… and the simple joy of painting outdoors. This is more than just a meet-up: **it’s a guided class designed to help you grow your skills while you enjoy the process.** We’ll start each session exploring essential watercolour techniques—wet-on-wet, layering, colour mixing, and transparency—and then apply them to what we see around us. You’ll learn how to approach different types of plants, how to simplify complex forms, and which techniques and effects work best for each subject. No experience needed—just curiosity, and a love for plants, light, and slow summer days 🌱 The workshop includes **two classes**, but you’re also welcome to join individual sessions. **When:** Wednesday 13 + 20 May From 6 to 7.30 PM **Where:** Friedrichshain, Berlin (You will receive the exact address by e-mail) **Price:** 50€ for the whole workshop (2 classes) Single class 27€ / Paypal & Bank Transfer **Material:** You will need a watercolour set, watercolour paper (or sketchbook) and brushes.

🕢 Doors open at 18:30 and sessions start at 19:00. Freestyle vocal workout at and play session. €8-20 😌 Flow is a state of being… an experience when you allow yourself to be 100% fully engaged in the present moment in a feedback loop between clarity and satisfaction. It is an undeniable sensation where things seem to be more effortless, pleasurable, in sync, and you can easily sense a connection with something greater than yourself; this is what we will create…: • a connected and mindful meditation where it is possible to blissfully surf the cutting edge of the present moment together… • a game where it’s possible to feel excited and calm in the same moment, and everyone can win as much as they like… Scott Bolden, founder of Das Baumhaus Berlin will share some very easy, practical and effective methods developed during the last 12 years of facilitating the “Improvisational Groove Orchestra” (I.G.O.) improv vocal jam sessions. Within 20 minutes participants learn to use the common sound space to create resonance in the form of improvisational music where it is quite common to experience some real flow moments… It is very easy to participate, no musical talent or training is required so anyone is welcome to join. All of the session is done with eyes closed to avoid visual distractions and keep focus on the co-created sound space. During these sessions we will also have short breaks for feedback and refreshment. Important – Please be on time. It is very important to understand the methodology and warm up in the group before joining in! 🎤 @21:00 - Freestyle vocal workshop and practice session. €8-15 Have you ever wanted to learn how to do freestyle vocalizations?

Tauche ein in die wohltuende Welt des *Heilsamen Singens*! In der Singgruppe erleben wir gemeinsam, wie einfache, wiederholende Lieder mit positiven Texten Herz und Seele berühren. Du musst kein*e geübte*r Sänger\*in sein – beim heilsamen Singen geht es nicht um Leistung, sondern um Verbindung, Freude und Entspannung. Teils sanfte, teils kraftvolle Klänge und Melodien laden dich ein, den Alltagsstress hinter dir zu lassen, bei dir selbst anzukommen und neue Lebensfreude zu spüren. Beim gemeinsamen Singen entsteht innere Ruhe, dein Immunsystem wird gestärkt – und auf liebevolle Weise entsteht Verbindung untereinander. Komm, wie du bist – mit deiner Stimme, deinem Atem, deinem Herzen. Lass dich tragen vom Klang und entdecke die heilende Kraft des Singens. Wir freuen uns auf dich! Wo: Offenes Wohnzimmer Moabit Wann: jeden 3. Freitag im Monat 19:00 Teilnahme auf Spendenbasis Um die Planung zu erleichtern, melde Dich gerne an unter: [kontakt@heilsames-singen-berlin.de](mailto:kontakt@heilsames-singen-berlin.de) (Wer spontan kommen kann, ist natürlich ebenso willkommen!) Hei, ich bin Gesa, Sängerin, Gesangspädagogin und zertifizierte Singleiterin für Heilsames Singen. Nach über 20 Jahren als Opern- und Konzertsängerin liegt mein Fokus heute auf dem „Heilsamen Singen“. Mir liegt am Herzen, das Singen wieder in unseren Alltag zu holen. Weil es uns mit unserem innersten Menschsein verbindet, weil es Herz und Seele berührt – und weil es ein kleiner, aber kraftvoller Beitrag zu mehr Freude, Wärme und Menschlichkeit in unserer Welt ist.

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!
