Happiness

Hola good people, We are thrilled to announce our next GreeceJS meetup, happening on 18th of March, from 18:00 to 20:30, at a brand new venue in the center of Athens hosted by Yodeck! ⚠️ **Important:** This venue is new for our community and has a **capacity of 50 people**, so make sure to **secure your spot early**. 📍 **Location:** **Starttech Ventures — 1 Lykourgou Street, Athens 10551** Just a short walk from **Omonia Square**. Please note: the talks in this meetup will be conducted in **Greek (EL)**. Our speakers this time are **Thanos Karagiannis** and **Spiros Martzoukos**, two engineers with decades of combined experience across the JavaScript ecosystem, product engineering, and modern web architectures. Our event is proudly sponsored by **Yodeck** — a fast-growing SaaS company revolutionizing digital signage. As always, the event will be live-streamed via our YouTube channel, and we’ll be sharing the link in our Slack / Instagram, so make sure to join us there! We look forward to seeing you **@ Yodeck** 🎉 **Event Agenda** **18:00 – 18:30** **Networking & cold beverages** Come early, grab a drink, and meet the community! **18:30 – 19:15** **Thanos Karagiannis – “I Was Wrong About AI Coding” (EL)** **Staff Engineer at Causaly \| GreeceJS Co\-organizer** Thanos is a software engineer with 15+ years of experience, fluent across the JavaScript stack — from React frontends to Node.js services. He currently works as a Staff Engineer at Causaly, focusing on backend systems. He’s also a GreeceJS co-organizer. Outside of work, you’ll find him fueled by coffee and out on his bike. Most of us started with AI coding tools the same way — autocomplete, boilerplate, small refactors. Helpful, but not transformative. It was easy to be skeptical. But something shifted. This talk is a personal journey — from dismissing AI coding as “fancy autocomplete” to integrating it into real engineering workflows. Thanos will share what actually works, what doesn’t, and why the engineers who benefit most from AI aren’t the ones who write code faster, but the ones who make better decisions faster. **19:15 – 19:30** **A word from our sponsor: Yodeck** Yodeck is a fast-growing Software-as-a-Service (SaaS) company that is laser-focused on disrupting the $23B digital signage industry. Yodeck’s affordable, easy-to-use, and feature-rich solution has been developed to democratize digital signage and empower any and every business around the world. Yodeck was first introduced in 2016 and now powers over 220,000 screens across every type of business — from restaurants and retail stores to schools, stadiums, and conference halls. **[Check out their openings](https://2ly.link/25ysK)!** **19:45 – 20:30** **Spiros Martzoukos – Local-First Apps: Instant UX without the Spinner** Spiros Martzoukos is a Senior Product Engineer at Checkly with 20+ years of experience spanning full-stack engineering, product design, and product management. He has worked across startups and scale-ups including Contentful, Prisma, and Clerk, and is the founder of Makkuro, a next-gen project management tool for digital product teams. He is passionate about building lean, user-first products end-to-end — and making sure your AI apps work reliably well. In this talk, Spiros shows how local-first architecture can eliminate every spinner from your app, delivering instant sub-100ms interactions that feel like magic while dramatically reducing infrastructure costs. He will break down the seven principles behind this approach and share practical lessons about where it shines (B2B SaaS and productivity tools) and where today’s tooling still needs to mature. **21:00** **BeerJS 🍻** We’ll wrap up with informal chats over beers at a nearby place — details will be shared via **Slack**! **Venue Information** **Starttech Ventures** 1 Lykourgou Street, Athens 10551 **Doorbell:** 03# Starttech Ventures 🚨 **Important reminder:** The venue fits **50 attendees**, so please **RSVP early**. **Getting There** **By Metro** Take **Metro Line 1 (Green)** or **Line 2 (Red)** to **Omonia Station**.

🗓️ Το **Causal Data Science Meetup της Αθήνας** σας περιμένει στις **19 Μαρτίου, 7:00 μμ** για την 6η συνάντησή του! Καλεσμένος μας ο **[Christos Diou](https://diou.github.io/)**, ο οποίος θα μας μιλήσει για **"Causal Representation Learning: From Pattern Matching to World Models"**. Στην ομιλία αυτή θα δούμε πώς το representation learning μπορεί να εμπλουτιστεί με αιτιώδη δομή. Μέσα από τη θεμελιώδη αρχή των ανεξάρτητων αιτιωδών μηχανισμών και αναφορές σε καθοριστικές εργασίες του πεδίου, θα παρακολουθήσουμε την εξέλιξη του causal representation learning από θεωρητική ιδέα σε ενεργό ερευνητικό ρεύμα που επηρεάζει τη σύγχρονη μηχανική μάθηση. Θα γίνει επίσης μια εισαγωγή στη νέα βιβλιογραφία των *world models*, που στοχεύει σε συστήματα AI ικανά όχι απλώς να προβλέπουν, αλλά να προσομοιώνουν και να συλλογίζονται για το πώς αλλάζει ο κόσμος. Το event θα περιέχει Q&A, networking και τα σχετικά συνοδευτικά. Ραντεβού **στο Impact Hub την Πέμπτη 19 Μαρτίου** στις **7:00 μμ**. Ευχαριστούμε για την υποστήριξη την **Plum**, την **Intelligencia AI** καθώς και το **κέντρο Beyond του Εθνικού Αστεροσκοπείου Αθηνών**. 🚀 Κάνε **RSVP** και μη χάσεις την ευκαιρία να βρεθείς στην 5η συνάντηση της Causal Data Science κοινότητας της Αθήνας! Η πλήρης περιγραφή της ομιλίας στα Αγγλικά: *Modern AI systems have become remarkably good at recognizing patterns, however statistical pattern matching alone is not enough to build systems that are robust, generalizable, or capable of reasoning about cause and effect. In this talk, we explore how representation learning, which aims to equip machines with structured internal models of their inputs, can be enriched with causal structure to produce more reliable and interpretable AI. We will begin with an introduction to representation learning and its limitations, then examine how incorporating the principle of independent causal mechanisms changes the way models represent and respond to their environment. Drawing on landmark papers in the field, we will trace how causal representation learning has evolved from a theoretical idea into a practical framework shaping modern machine learning research. We will also touch on the recently emerging world model literature, which envisions AI systems that go beyond reactive prediction to simulate and reason about how the world changes. The talk concludes with a forward-looking discussion of where this field is headed and what it may mean for the future of reliable, trustworthy AI.*
