Design Management

Software engineering is changing. Dramatically. Writing code today isn't what it used to be ... a mere few weeks ago. As AI coding agents start gaining more widespread adoption, "best practices" are still unclear. Nobody can still say for sure what should go in AGENTS.md, what the secret sauce for a good skill is. In this hands-on, [mob programming](https://www.baeldung.com/cs/mob-programming) session, we'll practice using some agents together, **learning from each other** as we go along: * how do we best prompt the agents to build a feature? * how can agents help with code review ? (we'll try out Mozilla's [star-chamber](https://blog.mozilla.ai/the-star-chamber-multi-llm-consensus-for-code-quality/) that gets multiple LLMs to review our code - and to discuss with each other before telling us the output) * spend the time in between discussing skills, subagents, hooks, and whatever else is new by then. Note: this is not *intended* to be claude code - focused, but it might turn out to be. If you have another favourite agent, please come along and show us how to use that instead! ;) **Sponsors** Our sponsors for this meetup are [Yodeck](https://www.yodeck.com/) \- who are not only kindly providing the venue\, free of charge\, but who will also treat us to some snacks / drinks for the networking session after the meetup\! Do stick around and say hi!

Hello DDDers, Just before the easter break, it's time to practice our data engineering chops! Let's welcome [Theodore Pantazopoulos](https://www.linkedin.com/in/teopant/) on stage, where he shall present his work on avoiding infrastructure traps and finding better ways to think about data and building leaner systems that scale. Stick around after the talk - not just for pizza, beers, and networking, but also because two lucky participants will win tickets for the upcoming [Devoxx](https://devoxx.gr/) conference, that takes place at the end of April, and features a stellar speaker lineup. We also have some announcements for the next meetup, where we will celebrate the 10th anniversary of this community! **Talk: Beyond the Pipeline: A Smarter Paradigm for Data Engineering** For decades, the default response to every data challenge was the same: add more infrastructure. More servers, more pipelines, more complexity. This talk challenges that assumption. We'll explore how a fundamental shift in thinking, treating data producers as partners in a contract rather than passive sources to be queried, can eliminate entire layers of engineering overhead, reduce costs, and simplify architectures that have grown unnecessarily complex. This paradigm proves especially powerful in constrained resource environments, whether that means teams and organizations that cannot afford over-engineered pipelines or expensive clusters, or architectures that are constrained by design, such as microcontrollers, embedded systems, and edge devices where compute and memory are fundamentally limited. **Speaker bio** Theodore has been shipping data infrastructure that actually scales. As a Principal Engineer, creator of the open-source streaming-sql-engine, and contributor to numerous open-source projects, he's built large-scale data processing systems that power core products and drive business decisions. With experience across global corporations, high-growth startups, and industry leaders such as Citrix, Delivery Hero, and shopflix, and deep expertise in Go, Python, and data engineering, he specializes in turning complex data challenges into reliable, high-impact solutions. **Meetup Outline** 18:30 - 18:45 Warm welcome 18:45 - 19:45 Talk by Theodore 19:45 - 20:00 Devoxx ticket giveaway 20:00+ Networking & Discussions **Sponsors** XM is kindly hosting the event on their premises, which are located only 5' on foot from Megaron Athens.

Αγαπητοί UXers, Ελπίζω όλοι να είστε καλά! Μετά από ένα διάστημα απουσίας (έτσι για να σας λείψουμε) ήρθε η ώρα να ξαναβρεθούμε. Ανακοινώνω το επόμενο UX meetup της κοινότητάς μας το οποίο θα είναι δια ζώσης και αυτή τη φορά έχουμε τη χαρά να φιλοξενηθούμε από τη Epignosis. H εταιρία (ένα ελληνικό και πραγματικό success story) έχει καταφέρει να είναι από τις μεγαλύτερες παγκοσμίως στο ιδιαίτερα ανταγωνιστικό industry του e-learning. Το meetup περιλαμβάνει ως συνήθως μια κεντρική ομιλία σχετικά με UX πρακτικές, μεθόδους και διαδικασίες. Πιο συγκεκριμένα η εν λόγω ομιλία αφορά σε θέματα συμπεριληπτικής σχεδίασης και ψηφιακής προσβασιμότητας της πλατφόρμας TalentLMS. Η agenda έχει ως εξής: 1\. 19\.00 \- 19\.05: Ένα πολύ σύντομο introduction για το meetup 2\. 19\.05\- 19\.45: "From Inaccessible to Inclusive: Our Team’s Accessibility Journey\.” \- Αλέξανδρος Αντωνιάδης\, Lead Frontend Engineer\, Epignosis\. 3\. 19\.45\-20\.45: Q & A \+ networking H προσέλευση είναι στις 18.30 - 19.00 και όπως πάντα μετά την ομιλία θα έχουμε χρόνο Q&Α και φυσικά για networking, snacks & drinks! Παρακαλούμε όσους παρεβρεθούν στo event να έχουν μαζί τους και ταυτότητα. Θα τα πούμε από κοντά στις 31 Mαρτίου! Παναγιώτης

📅Την Κυριακή 5 Απριλίου, ώρα 15:00 και σχεδόν στην καρδιά της Άνοιξης, ξεκινάμε από την μονή Αγίου Ιωάννη Κυνηγού στην Αγία Παρασκευή για να πιάσουμε μία από τις κορυφές του Υμηττού. Την κορυφή Κορακοβούνι! 🎋 Πρόκειται για μία όμορφη ημικυκλική διαδρομή 8,5 χιλιομέτρων στον Βόρειο Υμηττό, με αρκετές εναλλαγές τοπίων αλλά και γεμάτη με εντυπωσιακά σημεία θέας προς το λεκανοπέδιο! (Δείτε τις φώτο πιο κάτω) Στη πορεία μας θα συναντήσουμε και το περιβόητο σπήλαιο λιονταριού! Το όνομα του σπηλαίου δεν είναι τυχαίο. Περισσότερες λεπτομέρειες στο σημείο. ⚠️ ΠΡΟΣΟΧΗ: Η διαδρομή αν και σχετικά μικρής απόστασης ΔΕΝ λογίζεται ως εύκολη ή κατάλληλη για αρχάριους. Το πρώτο μισό της διαδρομής έχει ανοδική κλίση, ή όποια σε διάφορα σημεία αυξομειώνεται. Το δεύτερο μισό έχει και κάποια σημεία με έντονη καθοδική κλίση. Επίσης το 80% της διαδρομής είναι μέσα από μονοπάτια. ⌛ Η διάρκεια της μετρήθηκε επί τόπου με scouting στις 3 ώρες, ωστόσο για όσους επιχειρήσουν να το τολμήσουν, ας γνωρίζουν ότι ο ρυθμός θα είναι απόλυτα χαλαρός, με μπόλικα διαλείμματα και χωρίς πίεση χρόνου. Γι αυτό επιβάλεται να πάρετε μαζί σας και φακό. Διότι δεν ξέρουμε αν οι 3 ώρες γίνουν 5 στο τέλος λόγω μείωσης του ρυθμού βάδισης ή της αύξησης αριθμού στάσεων! 🤷🏻‍♂️ Εκτός από φακό, μαζί σας πρέπει να έχετε και: 💧 ΤΟΥΛΑΧΙΣΤΟΝ 1 λίτρο νερό. Ιδανικά 1,5. 👟Αντιολισθητικά υποδήματα 🧢 Καπέλο (προαιρετικά) 🦯 Όσοι έχουν μπατόν ας τα φέρουν θα φανούν χρήσιμα. Και όσοι δεν έχουν, αν σκέφτονται να αγοράσουν, μάλλον τώρα είναι η κατάλληλη ώρα. Δεν θα το μετανιώσουν. Ειδικά όσοι δεν έχουν πολύ καλή φυσική κατάσταση. 😎 Επίσης απαραίτητο κρίνεται: 😋Την προηγούμενη μέρα να έχετε φάει καλά. 🍌🥜 Την ημέρα της δραστηριότητας να έχετε κομμένα νύχια ποδιών (ναι!) και μαζί σας ενεργειακά σνακ όπως, μπανάνες, σταφίδες, ξηρούς καρπούς ή έστω ενεργειακές μπάρες. 🗺️ Εδώ είναι το ακριβές [στίγμα συνάντησης](https://maps.app.goo.gl/68xZp6Y8rpc56eJg9) 👈🏻 ✍🏻 Συμμετοχή μπορείτε να δηλώσετε μόνο μέσα από αυτή [την φόρμα ](https://luma.com/6rnovtzz)👈🏻

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

Start your week the right way with Manic Mondays. Giving you an enjoyable Bachata lesson with a push of cool moves. The second hour has Beginner/Intermediate Salsa on 1.

**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.
