New Product Development: Software & Tech

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/.

**​What if your next step isn't another job, *but something of your own*?** In this hands-on workshop, you'll turn your experience into a simple business idea and define a realistic first step to test it. **Gather & Grow - Copenhagen** invites you to an exciting workshop in collaboration with **[Spark Coaching with Val](https://www.linkedin.com/in/valeriakadelski/?utm_source=luma)**! IMPORTANT NOTE: To reserve your ticket for this event, the cost is 100 DKK payable by MobilePay. This must be paid prior to attending.

**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*

**Tired of small talk? Come meet new people meaningfully - the Authentic You Me way!** **\*\*\*Looking to grow your social circle? Join us for a welcoming, carefully crafted and thoughtfully facilitated experience of meaningful conversations that go beyond the small talk.\*\*\*** No business cards or job titles. No small talk. No pressure to perform. No intimidating crowds. \-\-\- If you have answered yes to two or more of the above, then you have come to the right place. **Welcome to Authentic You Me** We often hear how difficult it can be to make new friends as an adult and particularly when moving abroad; or when rebuilding social circles cos old friends have moved away or onto new life phases. Socialising attempts often mean standing in a crowded room, wearing a polite smile, and answering the same three questions: *"What do you do?" "Where are you from?" "How long have you been here?"* Great for breaking the ice, but rarely leading to something inspiring or meaningful. It’s exhausting. It feels like a performance. While the absence of authentic connection and meaningful conversations can sometimes leave us feeling a little lonely or like we don't belong. **Authentic You Me** *was born with a desire to change that.* \-\-\- \*\*\*𝗪𝗲𝗹𝗰𝗼𝗺𝗲 𝘁𝗼 𝗔𝘂𝘁𝗵𝗲𝗻𝘁𝗶𝗰 𝗬𝗼𝘂 𝗠𝗲, the home of mindful, intentional socials we baptised as 𝗦𝗹𝗼𝘄 𝗙𝗿𝗶𝗲𝗻𝗱𝗶𝗻𝗴 - our own thoughtful, refreshing and carefully crafted way of changing how we meet and connect with others. Join me for a carefully and lovingly curated slow-friending evening that is all about embracing your authentic self, connecting on a deeper level with like-minded people, challenging your perspective and sparking curiosity through stimulating conversations – all in a welcoming, non-intimidating & hyggelige setting. Designed to suit both introverts & extroverts. . . **\*\*\*Please note that this is a mission-led PAID event.

“I don’t know what I want.” If that thought sounds familiar, you’re not alone—and you don’t need a perfect answer to move forward. In this workshop, we’ll explore what *pulls you*—without the pressure of choosing a “right” path. Through simple exercises, you’ll: • Reflect on moments where you felt engaged or energized • Discover patterns in what you enjoy (and what you don’t) • Create a clear “more of / less of” list for your future By the end, you’ll have a better sense of direction—and a few ideas worth exploring. 🧭 Part of a 6-part series, but open to everyone (even if you missed the first one). Curiosity is enough. You don’t need clarity yet.

Do you want to improve your eyesight naturally, but don't know how to start? Then this event is perfect for you. I have through deep learning in the field of eyesight gained knowledge about how our eyes work internally and how one can improve ones vision, through practical yet focused and specific eyesight exercises. In this event we will first go through the basics of the eyesight functions to later talk about very useful exercises which you can use to gradually improve eyesight. The event is open to everyone and not only for people with specific medical condition. Its also completely free of charge. You will take home very detailed exercises that can help you make your eyesight better, more comfortable to use and notice all the important signs of correct use of the eyes which will ensure sharp and joyfully eyesight experience. It starts from proper relaxation that we forgot subconsciously how to do through our long commitments we have that falls on the eyes. If you have any specific questions about the event, feel free to reach out to me before. ... We will meet at 2 pm at Stadsbiblioteket second floor "språkrummet", will update more precise location closer to the event

**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City.
