Join our next week’s Thursday Gathering to explore what happens when CODE MEETS COMMUNITY!
Our event brings together technology and business ecosystems to examine how AI and emerging tools are transforming modern work. Sessions will combine hands-on experience with strategic insights, covering topics from software development and the future of education to market expansion. Don’t miss the chance to gain actionable knowledge and build meaningful connections.
Plus, our Open Pitch Session welcomes participants ready to showcase their ideas to our network! On April 9, step into a space where technology, creativity and community come together!
If you’ve been to previous editions, you already know the vibe: great talks, diverse tech perspectives, and plenty of opportunities to meet people from across the Warsaw dev scene. If not - this is the perfect moment to experience it.
What to expect?
A Ruby-focused meetup as part of a larger, multi-community event
Networking with developers from different tech stacks
Talks and sessions (agenda coming soon!)
The unique energy of Behind The Code
This time we prepared for you two topics: "AI Gateway - what is it for? Does my project need one?" and "Beyond Senior: The Path to Staff Engineer in a Global Organization".
AI Gateway – What Is It For? Does My Project Need One?
If you're curious about AI Gateways and their role in modern projects this session is for you! Jakub will explain their purpose, lessons from the LiteLLM attack, and insights from his open-source AI Gateway GOModel (https://github.com/ENTERPILOT/GOModel/) helping you decide if your project needs one.
Beyond Senior: The Path to Staff Engineer in a Global Organization
You’ve reached Senior—but what comes next? This talk maps the path to Staff Engineer, exploring real-world frameworks, archetypes, anti-patterns, and practical tools to amplify your influence across teams in global organizations.
Whether you’re a long-time PLRUG regular or just Ruby-curious, come join us for an evening of learning, sharing, and community.
Come for Ruby, stay for the people.
During the workshop, participants will explore how immersive environments and the metaverse can be used to create engaging experiences for organizations, initiatives, and audiences. Building on the EUonAIR project and its virtual learning environment, the session will introduce key metaverse concepts and invite participants to reflect on how virtual spaces, avatars, interactive elements, and storytelling can support communication, visibility, and engagement. The workshop will have a practical and inspiring format, combining a presentation with a short interactive exercise and discussion.
Are you ready to level up your app development game? Join our upcoming vibecoding workshop where we'll teach you how to create innovative and valuable apps while solving problems using the power of vibecoding. This hands-on workshop is designed for anyone looking to enhance their skill set and take their projects to the next level. During this dynamic session, you'll learn the art of vibecoding – a unique approach to app development that emphasizes creativity, efficiency, and problem-solving. Our experienced instructors will guide you through the process, sharing valuable insights and best practices along the way. But that's not all! In addition to the comprehensive learning experience, you'll also have the opportunity to witness a live app build in action. See firsthand how vibecoding can transform ideas into reality and discover the endless possibilities that this innovative technique has to offer. Whether you're a seasoned developer or just starting out, this workshop will inspire you to think outside the box and explore new ways to create apps that stand out in today's competitive market. Don't miss this chance to boost your skills, network with like-minded individuals, and unleash your creativity with vibecoding!
Czym jest Garbage Collector? Wielu programistów odpowie niczym św. Augustyn zapytany o naturę czasu: Jeśli nikt mnie o to nie pyta, wiem. Jeśli pytającemu usiłuję wytłumaczyć, nie wiem. Spróbujmy zatem opowiedzieć o tym elemencie języka. Czym jest? Jak działa? A przede wszystkim, czy jako programiści powinniśmy się nim przejmować.
NRW.Global Business – The Trade and Investment Agency of Germany’s largest federal state, North Rhine-Westphalia (NRW)
With our strong headquarter in Düsseldorf and 12 international offices, including one in Poland, NRW.Global Business supports companies from NRW in their international expansion and assists foreign investors in starting operations in Germany. All non-profit, as your success is our success. With becoming #TeamNRW we support you in Germany, in Poland and globally.
NRW – Germany’s leading economic region – offers:
- optimal growth conditions based on a strong domestic market (~ 872 Mrd. €) that is called home by 1/4 of Germanys biggest companies, 1/3 of Germanys hidden Champions and over 20,000 international companies
- Innovation and Diversity driven by 68 leading universities, 60 science institutes, more than 750.000 students and a cosmopolitan environment
- a future-oriented economy developing solutions in DIGITALIZATION and the energy transition with high investments & several clusters
- The ICT sector is of tremendous importance to us, as it plays a key role across major focus areas such as Manufacturing, Mobility, the Green Economy, Life Sciences, and Security & Defence.
In addition to our traditional investment support services, one of our core strengths lies in opening doors through targeted B2B events – both in North Rhine-Westphalia and in Poland.
I once believed great software came from perfect APIs and a single universal style. That belief didn't survive contact with reality. Software is also defined by usefulness, strategy, trade-offs, and even human emotion. Through the lens of CPython, I'll share a journey of fixes that weren't worth making, "brilliant" ideas that didn't cut it, and surprisingly simple edge cases in your code that you'll never unsee.
Take the stage and pitch your idea!
Seize the opportunity to connect with the Venture Café community during our Open Pitch Sessions. Selected startups will have around 5 minutes to present their solutions, followed by immediate feedback from a panel of expert reviewers. It’s a unique chance to engage with startups, angels, and investors – all in one place!

For the Audience – How to Give Valuable Feedback:
- Be Clear and Direct: Keep feedback concise, focusing on specific areas for improvement.
- Get Specific: Break down your insights into actionable points – think clarity, design, coherence, etc.
- Offer a Comprehensive Critique: Provide constructive feedback on slide count, content density, timing, storytelling, and presentation style (avoid reading from a phone!).

Codziennie słyszymy o potencjale AI, ale ile osób widziało ten potencjał na żywo?
Michał pokaże w czasie rzeczywistym, jak za pomocą ekosystemu Claude - Claude Cowork i Claude Code - automatyzuje powtarzalne zadania, generuje gotowe materiały biznesowe i buduje narzędzia szyte na miarę, bez zespołu programistów. Dzięki connectorom Claude łączy się bezpośrednio z narzędziami firmowymi, omijając tradycyjne platformy do automatyzacji.
Poznacie konkretne zastosowania, zobaczycie efekty na żywo i dostaniecie praktyczną ścieżkę, jak przetestować i wdrożyć te rozwiązania u siebie w firmie.
Dla founderów, dyrektorów i menedżerów, którzy wolą zobaczyć niż usłyszeć, że AI zmienia reguły gry.
This session approaches multi-agent systems from a distributed systems perspective. Rather than focusing on individual agents, we will examine how to design and operate systems composed of multiple decision-making components interacting with traditional services.
We will cover architectural patterns such as linear pipelines, DAG-based execution, and event-driven designs, and analyze how orchestration can be implemented using tools like LangGraph, Temporal, and Argo Workflows.
A significant part of the talk will focus on communication models: synchronous interaction via REST and gRPC, shared state approaches using databases or Redis, and asynchronous messaging via systems such as Apache Kafka and NATS. We will discuss trade-offs in coupling, latency, scalability, and failure handling.
We will also break down real-world system composition, including AI agents, microservices, data layers, and infrastructure, and address operational challenges such as retries, idempotency, observability, and cost control in distributed environments.
Finally, we will walk through a practical example, incrementally transforming a single-agent setup into a multi-agent architecture with explicit coordination and communication patterns.
