RSVP is mandatory. Spaces are limited. Please ensure you RSVP here. If your plans change, please update your status to help us manage venue capacity. A special thanks to Snappi for generously sponsoring the venue for us! See you there!

We are back with a new AWS User Group Athens meetup, and this time we are going deep into serverless, long-running workflows and the new possibilities unlocked by AWS Lambda Durable Functions. Modern applications often need to coordinate retries, state, delays, callbacks, human-in-the-loop steps, and distributed business logic. Traditionally, that usually meant external orchestration, explicit state machines, or custom persistence logic. In this meetup, we will explore how AWS Lambda Durable Functions can simplify that model by letting developers express reliable, long-running workflows directly in familiar programming languages. We will have two technical sessions: first, a deep dive into the core concepts of AWS Lambda Durable Functions and how they compare with AWS Step Functions; then, a practical session on building resilient conversational AI workflows with Amazon Bedrock agents and the Sinch Conversation API. A big thank you to **Epignosis** for hosting us at their HQ for this meetup. **Important venue information** This meetup will take place at **Epignosis HQ**. Please check the map and venue instructions carefully before arriving. The venue’s security team will be checking IDs at the entrance. For this reason: * You must provide your **full name** when RSVPing. * You must bring a **valid ID** for entry. * RSVP will close **2 days before the event** so that the attendee list can be shared with the venue. Please make sure the name on your RSVP matches your ID. *** **Agenda** **18:00 – 18:30:** Entry & networking **18:30 – 19:20:** Deep Dive on AWS Lambda Durable Functions Speaker: [Lefteris Karageorgiou](https://www.linkedin.com/in/lefteriskarageorgiou) **19:30 – 20:20:** Building Conversational Agents in Code with AWS Lambda Durable Functions Speaker: [Gunnar Grosch](https://www.linkedin.com/in/gunnargrosch/) **20:30 – open end:** Networking, 🍕🍻 *** **Session 1: Deep Dive on AWS Lambda Durable Functions** AWS Lambda Durable Functions makes it easier to build reliable, fault-tolerant applications using familiar programming languages like JavaScript, Python, and Java. In this session, we will explore how durable functions simplify retries, state management, and human-in-the-loop workflows for long-running processes, and how they compare with AWS Step Functions for orchestrating distributed applications. Through a live demo, you will learn how to use features like “steps” and “waits” directly in your IDE to handle failures, track progress, and orchestrate business logic with less complexity. **About the speaker** [Lefteris](https://www.linkedin.com/in/lefteriskarageorgiou/) is a Senior Solutions Architect at AWS with 20 years of experience in software engineering, specializing in serverless architectures. He is the author of the book **“Mastering Event-Driven Microservices in AWS”** and runs a weekly newsletter, **“The Cloud Engineers,”** where he shares insightful articles on cloud computing. Passionate about sharing his knowledge, Lefteris is a public speaker and frequently speaks at technical conferences such as AWS re:Invent, AWS Summits, and Devoxx. *** **Session 2: Building Conversational Agents in Code with AWS Lambda Durable Functions** Building multi-agent AI workflows usually requires complex state machines to handle unpredictable human delays. Building on the core concepts of AWS Lambda Durable Functions, this session dives into applied agent orchestration. We will coordinate Amazon Bedrock conversational agents using the Sinch Conversation API to handle inbound interactions. You will learn how to dispatch specialized AI agents, use callbacks to handle asynchronous human input natively, and build resilient, long-running chat architectures entirely in code. **About the speaker** [Gunnar Grosch](https://www.linkedin.com/in/gunnargrosch/) is a Developer Advocate at Sinch and an engineer with over 25 years of experience building software, scaling developer communities, and making complex technology accessible. He started as a community member, became an AWS User Group Leader, was named an AWS Serverless Hero, and spent more than five years as a Developer Advocate at AWS, rising to Principal. Gunnar sits between the people who build the tools and the people who use them, making both sides better by bringing community feedback back to product teams. *** Whether you are building serverless applications, distributed workflows, AI agents, event-driven systems, or just want to understand where Lambda Durable Functions fit in the AWS ecosystem, this meetup is for you. Join us for deep technical content, practical demos, great speakers, and the usual AWS community networking.

🇬🇷 **Athens, we're getting together — and this one's going to make you think differently.** The QA community in Athens is coming together on **June 4th** for an evening of bold ideas, sharp conversation, and the kind of networking that actually sticks. This edition explores two fascinating intersections that don't get talked about enough — what does linguistics have to do with Black Box Testing? And what happens when quality engineering meets SEO? More than you'd think on both counts. **AGENDA** **\- Welcome & Introductions** - **Featured Sessions:** **Knowing the Next Big Thing: Black Box Testing and Linguistics** *by Apostolos Moutiakas* When we test a system without knowing its internals, we're essentially decoding behaviour through inputs and outputs — not unlike how we interpret language. This session digs into that connection and what it means for how we approach quality. **The Engineering Side of SEO: Diagnosing Technical Website Failures** *by Anatoliy Molodechkin* SEO isn't just a marketing problem — it's an engineering one. This session explores how QA thinking applies to diagnosing and fixing the technical failures that silently hurt your website's performance. -**🍕F&B, Networking & Fun** Whether you're a seasoned QA engineer, a curious developer, or someone exploring the craft of software quality — this is an evening worth clearing your calendar for. Expect great conversation, good company, and networking with Athens' finest QA minds. **Spots are limited — RSVP now to secure yours!** 📍 Zone01, Athens 🗓️ Thursday, 4 June 2026 🕡 6:30 PM \| 3 Hours **A Few Notes:** ✅ This is an in-person event ✅ RSVP does not guarantee a seat — A confirmation email will be sent one day before the event.

**The Behavior Gap: Where Products Win or Lose** Teams today have more data than ever, and yet many still struggle to understand why customers adopt, engage with, or abandon their products. Teams sprint, ship faster, and chase more signals… all while metrics stall and confidence drops. The missing piece isn’t more data. It’s often the behavioral insight between the metrics, explaining why the numbers move in the first place. Dashboards can tell you what customers did, but understanding why they did it (and how to influence what they do next) requires a deeper blend of insights. This session is about closing that gap. Drawing from real-world experience designing and scaling products as [ZoCo Design](https://zocodesign.com/)’s CEO, [Lacey](https://www.linkedin.com/in/laceypicazo/) will share how to cut through the noise and identify the insights that actually change behavior—moving people, and moving metrics. You’ll learn: * Why understanding customer behavior is a quant and qual challenge * How to spot the signals that actually predict behavior change * Where AI accelerates insight, and where it creates distraction * How to get meaningfully closer to customers, without adding more tools This talk reframes how to evaluate performance and identify what levers actually improve it, helping your team to make smarter bets with greater confidence. Every meaningful outcome is driven by behavior change. And when you know how to design for behavior, you stop guessing, and start building things that work. **About Our Speaker** [Lacey Picazo](https://www.linkedin.com/in/laceypicazo/) is the Founder and CEO of ZoCo, a healthcare product studio that turns complex, high-stakes ideas into products that drive real-world adoption. She partners with healthcare organizations to uncover critical care delivery insights, focus product strategy through behavior design, and build solutions that patients and providers actually use.
