Ofir Glezer, Technical training manager and Project manager, Gilat Satellite Systems
You always felt that you had a great idea that can be transformed to a successful technical platform to be used by thousands of people ? join our presentation about methods for designing products from the idea stage up to an operational product. And once you have built a great product — can your teams, partners, and customers actually use it effectively? Our second part will reveals why knowledge design is often the missing link between innovation and adoption, showing how technical training, knowledge management, and AI can transform scattered expertise into a scalable competitive advantage.

11.20 - 12.00 | Beyond Linting: Building an AI Code Reviewer Grounded in Architectural Mental Models
Evangelia Mitsopoulou, Founder & CTO, Philomath Academy
Most AI code review tools catch bugs and style violations — Copilot, CodeRabbit, Cursor already do that well. This talk is about a different problem: how do you teach AI to review architectural thinking? I built a code review engine that runs on student PRs in GitHub Actions, grounded in proprietary React mental models: state colocation, derived state, composition patterns, lifting state. It doesn’t ask “is this a bug?” It asks “does this engineer understand why state should live here?” Attendees will learn how to combine static pattern detection (YAML rules with confidence scores and guard conditions) with LLM reasoning to produce feedback that goes beyond linting — feedback that coaches rather than criticizes. They’ll see why structured JSON output, hallucination filtering, and confidence gating are essential for production reliability, and how to encode years of principal-level judgment into a format an LLM can reason with. |
Andreas Symeonidis, Professor of Software Engineering, ECE AUTH – Founder, Cyclopt
During this talk we’ll discuss how the software engineering landscape has changed the last few years after the establishment of Vibe and Agentic coding. We’re to present state-of-practice tools, and stress the importance of secure coding, secure delivery and secure AI governance. We’re is going to preach in favor of DevSecOps, the latest and most prominent trend in Software Engineeing.
Nikos Zinas, Head of Engineer, PBLWorks
The job of writing software has changed more in the last eighteen months than in the previous ten years. Most of what’s said publicly is framed as either a threat or a sales pitch, and neither has been particularly useful to the people actually doing the work.
This is the talk Nikos would want to hear if he were early in his career today. He steps back and asks a simpler question: what is this job actually becoming?

Exploring how AI is reshaping the day-to-day reality of developers — from software development workflows and code quality to security concerns and the evolving role of the software engineer in the years ahead. Through practical examples, personal experience and real-world perspectives, the discussion will focus on what works and what does not in AI tools for developers, the trade-off between speed and quality, the new security risks introduced by code assistants, and what all these changes mean especially for younger developers. The session will also include time for audience questions.

Στον κόσμο του Software Development, τα πιο κρίσιμα bugs δεν βρίσκονται πάντα στον κώδικα, αλλά στον τρόπο που επικοινωνούμε. Σε αυτό το διαδραστικό workshop, αφήνουμε για λίγο το πληκτρολόγιο και μπαίνουμε σε ένα Live Communication Sprint. Μέσα από ένα σενάριο προσομοίωσης, θα εξερευνήσουμε πώς τα soft skills μπορούν να εκτοξεύσουν την απόδοση μιας ομάδας.
Pantelis Tsirigotis ,Senior Manager Engineer Lead, Pfizer Hellas
Alexandros NtagkonikosManager Cloud Engineer, Pfizer Hellas
Ξέχνα το παραδοσιακό coding.
Το μέλλον του software engineering δεν είναι το “γράψιμο” κώδικα, αλλά η ενορχήστρωση (orchestration) AI agents. Σε αυτό το διαδραστικό workshop, σπάμε το φράγμα μεταξύ Junior και Senior επιπέδου, δείχνοντάς σου πώς να χρησιμοποιείς AI Agents ως το δικό σου προσωπικό “dev team”.
Τι θα κερδίσεις
The Senior Mindset: Πώς να σκέφτεσαι ως αρχιτέκτονας και όχι μόνο ως εκτελεστής.
Prompt Engineering & Logic: Η τέχνη του να “μιλάς” στους agents για να αποφεύγεις λάθη.
Real-world Delivery: Από το μηδέν στο deployment (Web & Cloud) σε χρόνο μηδέν.
Yianni Kolokythas, Software Engineering Director, BETA CAE Systems
AI is moving beyond simple chatbots. In this workshop, we will explore how Large Language Models can become “agents”: systems that can reason, use tools, retrieve knowledge, and complete tasks through natural-language instructions.
Starting from the basics of LLMs and the OpenAI SDK, we will build up to practical agentic AI concepts such as tool calling, multi-step execution, agent orchestration, Retrieval-Augmented Generation (RAG), vector stores, and the emerging concept of Claude Skills for packaging reusable AI capabilities. Through simple Python examples, participants will see how an AI assistant can move from answering questions to following a process, using external knowledge, and automating useful workflows.
This session is ideal for developers, engineers, students, and tech enthusiasts who want a clear, practical introduction to one of the most important shifts in AI application development. No deep AI background is required, just curiosity and a basic understanding of programming.
By the end, attendees will understand what AI agents are, how reusable skills fit into the agentic AI landscape, and how to start building their own.

Two missions. One uncomfortable truth: the code your AI writes in seconds can take weeks to secure. Build features for your app using AI assistants, then turn around and identify every issue you accidentally introduced. Live leaderboard, real code, real consequences and a workflow you can take back to your team on Monday.

Σε αυτό το workshop θα δούμε live πώς χτίζεται μια σύγχρονη web εφαρμογή με Elixir και Phoenix — από το πρώτο mix phx.new μέχρι real-time UI με LiveView, background jobs, caching, observability και integrations με εξωτερικές υπηρεσίες, συμπεριλαμβανομένων AI providers.
Στόχος δεν είναι μια εισαγωγή στη σύνταξη της γλώσσας, αλλά μια ξενάγηση στη φιλοσοφία και τα εργαλεία του οικοσυστήματος: γιατί το BEAM σας γλιτώνει τεράστια κομμάτια ενός σύνθετου stack που σε άλλα οικοσυστήματα θα απαιτούσαν δεκάδες βιβλιοθήκες ή ξεχωριστά services.
Το demo είναι scripted — δεν χρειάζεται να γράψετε κώδικα ή να φέρετε laptop. Θα φύγετε με ξεκάθαρη εικόνα του τι είναι εφικτό με Phoenix το 2026, και πότε αξίζει να το βάλετε στο toolbox σας.
