Drones Berlin
Fly High: Join Drone Events in Berlin
Flutter Berlin × CarOnSale
Thu, Jul 9, 4:30 PMJoin us for an evening of Flutter, Dart, and networking hosted by CarOnSale. We'll kick things off with a deep dive into one of Dart's newest language features, followed by a second session and plenty of time to connect with fellow developers from the Berlin Flutter community. **Schedule** **18:30 — Doors Open** Check in, grab a drink, and meet fellow Flutter developers from the Berlin community. **19:00 — Welcome Notes** A short introduction from Flutter Berlin and our hosts at CarOnSale. **Talk 1 — Hiding Complexity with Dart Extension Types — Roman** Extension types in Dart 3.3+ let you elegantly hide the real complexity behind clean abstractions. They enable powerful patterns for true compile-time singletons with strong privacy guarantees, while also letting you build robust zero-cost Value Objects that enforce domain invariants and create a clear ubiquitous language — all with zero runtime cost. **About Roman** Roman is a Google-awarded Flutter Developer and Staff Mobile Engineer at CarOnSale.de, where he has worked for 4 years as part of his 8 years of Flutter experience (and over a decade in design). He loves Dart as his primary language and Rust as a complementary one (along with TS/Swift), but believes strong programming fundamentals matter more than any specific syntax. In his role he mentors Flutter developers and shapes architecture solutions. Outside of work he prioritizes family and open-source. **Talk 2 — TBA** Our second session of the evening will be announced soon. **20:30 — Networking & Socialising** Meet fellow Flutter developers, exchange ideas, discuss the talks, and connect with the local community. **22:00 — Doors Close** We wrap up the evening and head home inspired with new ideas and connections.
Lessons from the Field: Scale, Availability, and Performance
Wed, Jul 8, 3:30 PM**[IMPORTANT NOTICE registration is HERE](https://luma.com/wh28yfqv)** **Please bring a valid ID (driving licence or passport) with you on the day, as it will be required for entry to the venue.** Join **Aerospike** **AWS, Adjust and Miro** for an evening of technical talks focused on the challenges of running real-time, business-critical systems at scale. Hear firsthand lessons from engineers managing large datasets, database migrations, and cloud infrastructure availability in production. From Miro's Redis-to-Aerospike migration on Kubernetes to AWS best practices for capacity planning and resilience, speakers will share practical insights gained from operating demanding workloads where performance and reliability matter. Connect with fellow engineers, architects, and technology leaders from Berlin's tech community over drinks and networking. **Agenda** **17:30 – 18:00 - Welcome & networking** **18:00-18:10 - Speed vs Capacity: Designing Data Systems for Real-Time Scale** *Dirk Möller, Regional Lead Germany and EE, Aerospike* In high-performance data systems, balancing RAM and disk is key to real-time performance at scale. This session explores the technical nuances of database architecture in today’s AI-driven era, where workloads demand low latency, massive scale, and adaptive infrastructure. Drawing on real-world, mission-critical systems, we’ll show how to achieve the right mix of speed, scale, cost-efficiency, and reliability - designing architectures that meet today’s real-time demands while staying sustainable and affordable. **18:10 – 18:30 - Scaling Beyond Millions of Transactions** *Leonardo Muñoz, Platform Engineer, Adjust* A behind-the-scenes look at how Adjust powers high-throughput, low-latency workloads at scale using a distributed database platform running on bare metal infrastructure. Leonardo will explore the architectural and operational decisions behind the deployment, the challenges of managing dedicated hardware at scale, and the lessons learned from years of production experience supporting mission-critical workloads. **18:30 – 18:50 - Pod Ready ≠ Data Safe: Migrating a Critical Dataset on Kubernetes** *Yuriy Chernikov, Staff Software Engineer, Miro* Miro migrated one of its most critical datasets from a legacy caching platform to a modern distributed database running on Kubernetes - and not everything went according to plan. This practical talk covers what the migration actually required, the design decisions that made failures survivable, and the operational lessons that only emerge when managing datasets measured in terabytes. **18:50-19:10 - Managing Amazon EC2 Capacity and Availability** *Nati Cohen, Sr. Specialist Solutions Architect, Compute, AWS* Modern data-intensive applications require infrastructure that delivers high performance, scalability, and resilience. Organizations often seek to leverage the latest storage-optimized EC2 instances, select larger instance sizes for improved performance, place infrastructure close to data producers and consumers, and scale efficiently as business demands grow. In this session, we'll explore how to balance these performance requirements with cost optimization and capacity availability. We'll review the various EC2 capacity and reservation models, including Capacity Reservations, On-Demand Instances, Savings Plans, and more. Learn how to combine these options to optimize cost, performance, and availability for large-scale production workloads **19:00-20:00- Networking** **[IMPORTANT NOTICE registration is HERE](https://luma.com/wh28yfqv)**
Chiron in Taurus
Wed, Jul 8, 4:30 PMJoin us for an evening of fascinating discussion around the ingress of Chiron into the sign of Taurus on the 19th of June this year, and will stay in the sign of the Bull until 2034 (with a few trips retrograding back into Aries in between). Together, we’ll look at: •A review of Chiron and it's significations, and how can we use it as a tool for self growth. •What does the wounded healer mean in the sign of Taurus? What is the aspect that it's inviting us to "heal"? • What does it mean on a collective level? •The first Chiron return since Chiron's discovery in 1977. It's something astrologically unprecedented in our lifetimes. This meetup is a space for curiosity, reflection, and meaningful conversation — whether you’re deeply into astrology or just beginning to explore it. Bring your birth chart and, if possible, charts from friends and/or partners to discover the connections written in the stars. 🌙✨ **Guidelines**: – Start: 18:30 sharp (arrive earlier if you like) – Please stay on the topic of astrology – Respect, warmth, and honesty are essential – Kindly RSVP in advance, as we need to confirm with the venue -Please pay for your beverages or food as you order them. PS: We'll be in the terrace of the 2nd floor bar of Motel One. Warm regards, Maca, Sara, Tay, and Eric *We collect a 5€ cash contribution on site to support the platform costs.*

MONOPOLY Night (Game of Thrones Edition) 🐉
Sun, Jul 26, 3:00 PM***Winter is coming.* So are bad trades, fragile alliances, and somebody flipping the board after stepping on King’s Landing with a hotel on it. 👑** Join us for a **Game of Thrones Edition MONOPOLY Night**, where noble houses rise and fall over fake money, questionable deals, and pure stubbornness. 🐉 Expect shady alliances, financial ruin, and at least one person becoming drunk with power after acquiring the railroads. **By a miracle, let’s hope we’re still friends in the end. :p** 👉 We’re asking for a small 1.50€ participation fee because previous gaming meetups had quite a few no-shows, and Monopoly really only works if everyone who RSVPs actually shows up ready to destroy each other financially. **All money collected will go straight into snacks and treats for the group** 🍿 🐉 Come claim your territory, bankrupt your friends, and discover who among us would survive exactly three days in Westeros if Westeros had evolved into a late-stage capitalist banking spectacle. <3
Agentic AI in the Wild: What Actually Runs in Production
Wed, Jul 8, 3:00 PM# Connected Intelligence: AI Builders Meetup — WeAreDevelopers PreDay, Berlin AI agents are moving into production. The question is no longer whether to use them, but what it takes to make them reliable once the demo is over. This WeAreDevelopers PreDay meetup brings together builders, founders, and practitioners integrating AI agents into real codebases, CI/CD pipelines, developer platforms, and knowledge systems. The evening focuses on the conversations that rarely fit into conference talks: what breaks at scale, how context engineering works in practice, where failure modes hide, and how teams build systems they can trust. Under the theme **Connected Intelligence**, we will explore graph-based reasoning, constraint satisfaction, agentic code review, AI-powered development workflows, and Java’s evolving role in AI systems. No vendor pitches. Just practical lessons from systems running in production. **## Agenda** **-** 17:00 **— Doors Open, Drinks & Networking** **-** 17:30 **— Welcome & Opening Remarks** **-** 17:45 **—** Andreas Kollegger**, Director of GenAI, Neo4j** **-** 18:10 **— Break, Food & Networking** **-** 18:35 **—** Panel: ***Agentic AI in the Wild*** **-** 19:20 **—** Charles Francoise**, Staff Software Engineer, CircleCI** **-** 19:45 **—** Ana M**aria Mihalceanu**, Java Champion Alumni & Developer Advocate, Oracle - **20 **25 ****— Closing Remarks # Speakers and Session ## Andreas Kollegger — Director of GenAI, Neo4 ###* Where is the Zebra? Agent Decision-Making as Constraint Satisfactio* Zebra Puzzles provide a useful model for understanding agentic reasoning: they require structured constraint satisfaction rather than domain expertise Enterprise decisions such as loan approvals, compliance checks, resource allocation, and approval routing often hide similar constraint problems beneath layers of complexity This session examines how constraint networks, LLMs, and hybrid architectures approach structured decisions—and when agents need search, inference, generation, or a combination of all three ## Charles Francoise — Staff Software Engineer, CircleC ###* Plan with Opus, Code with Sonne* What if working effectively with AI agents is not only about choosing the best model, but choosing the right model for each task This session explores how different models can support planning, implementation, and development workflows—and how teams can use them together more effectively ## Ana Maria Mihalceanu — Java Champion Alumni and Developer Advocate, Oracl ###* Now and Next Java for A* AI does not have to remain a black-box REST endpoint. With JDK 25 and the Foreign Function and Memory API, Java developers can connect models directly to native runtimes such as ONNX for CPU and GPU inference The session demonstrates tensor mapping with` MemorySegmen`t, execution-provider switching, and self-contained Java inference applications. It also looks ahead to Project Babylon and the possibility of expressing model logic as analyzable Java code that can be lowered to accelerator backends # Panel: Agentic AI in the Wil What does it take to move AI agents from proof of concept into systems that operate reliably Practitioners from across the technology stack will discuss context management, governance, production workflows, failure modes, and what changes when agentic systems scale Expect concrete lessons, not talking points ## Moderato **Dana Fine — Open Source and Community Manager, Qod** Dana leads open-source programs and community initiatives at Qodo. She runs the GitHub User Group, CNCF local and GenAI communities, and the Bond AI meetup series ## Panelist ### Nnenna Ndukwe — Developer Relations Lead, Qod Nnenna is a software developer, applied AI researcher, and community builder with experience across med-tech, fintech, and media-tech. She focuses on integrating AI code review into enterprise and open-source development workflows ### Sebastian Kiste Sebastian is a cloud and enterprise transformation practitioner implementing production-ready architectures for Agentic AI Operations.
