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.

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.

Please contact me on WhatsApp if you’d like to join our group, as this group will soon be deleted from Meetup. 017684589930 Thanks, Marco We play every Sunday—year-round—and are looking for a few players who are willing to join regularly. Average age is around 27-50. We play on grass using poles as goals, which allows us to adjust the field and goal size depending on the number of players. Please arrive on time, as we need to divide the teams. Game starts 11:30 sharp. Wir spielen jeden Sonntag - ganzjährig - und suchen nach ein paar Spielern, die sich vorstellen können, regelmäßig dazuzukommen. Alter im Schnitt ca. 27-50. Wir spielen auf Rasen mit Stangen als Toren, wodurch wir die Platz- und Torgrösse flexibel a die Anzahl der Spieler anpassen können. Bitte pünktlich da sein, weil wir die Mannschaften aufteilen müssen. Das Spiel beginnt pünktlich um 11:30 Uhr.

**About this trip:** Some weekends are meant to help you slow down — this is one of them. We’re heading to Füssen for a long weekend that feels straight out of a postcard. Set in the Bavarian Alps, this trip is all about lakes, mountains, and slow moments in nature. Think clear blue water, scenic hikes, and views that don’t feel real — including the iconic Neuschwanstein Castle. The plan is to keep things simple and enjoyable. We’ll explore spots like Lechfall, walk through beautiful alpine trails, and take in some of the best views in the region — without rushing from place to place. There’s also plenty of time to just relax, enjoy the surroundings, and soak in the experience — whether that’s by a lake, on a trail, or during a sunset. It’s a short trip, but designed to give you a proper break from the usual routine. **Why travel with TripstoTales?** We organise small-group trips that are simple, well-planned, and easy to be a part of. Transport, stay, and the overall flow of the trip are already taken care of — so you don’t have to spend time figuring things out. You can just join and enjoy the experience. The group size stays small, which makes it easier to connect with others and keeps the trip relaxed and comfortable. If you’re looking for a scenic weekend getaway with a good mix of nature, light activity, and a social vibe, this trip is a great fit. **Trip Vibe** Style: Small-group curated Experience: Scenic & fairytale-like City Time: Minimal Activity Level: Easy–moderate Overall Feel: Calm & refreshing Ideal For: Nature lovers Age Group: Adults only Note : To ensure you dont travel with total strangers, we will also arrange a short 3-6 hours hike in the vicinity of Berlin so you get to know the other team members. “Feel free to message if you have any questions before joining 🙂” More information on : www.tripstotales.com Instagram : @tripstotales Join our Whatsapp community : https://chat.whatsapp.com/GbUXptOchFMDVuWubT7DNn

Join this Professional Communication session — to sharpen the skills for architectural pitches, elevator pitches, interviews. This time we meet in the Monbijou park. 💡 How it works The event is split into two parts: 1. **Communication (10 minute rounds)** – One participant answers a round of design and behavioral questions. Each other participant gets to ask him one question. 2. **Feedback Round** – The group provides feedback on communication, structure, and clarity. Constructive criticism is encouraged. 💡You will be asked: * **Light design problems** (high-level reasoning, not code) * **Behavioral questions** (“Tell me about yourself”, “Describe a challenge you faced...”) No need to prepare anything in advance — just bring curiosity and an open mind. 💡Note: location is the entrance to Monbijou park
