Speaker's Bio

Alexius Dionysius Diakogiannis is a Senior Solutions Architect and Squad Lead at the European Investment Bank, where he leads Front Office Lending applications, and the founder of AICollective Greece and Luxembourg. With more than 20 years of experience in enterprise technology, software engineering, and applied AI, he designs secure, resilient systems for highly regulated environments across banking and European institutions, mastering Java/JEE, the Spring ecosystem, and enterprise architecture along the way.
His work sits at the intersection of engineering and society. Holding an MSc in Artificial Intelligence and an MSc in Information Security & Digital Forensics – both with Distinction – Alexius explores how AI reshapes trust, security, and public discourse. His research on large-scale data analysis using PySpark and machine learning recently earned a Best Research Paper award, and his talks dig into AI bots, disinformation, digital forensics, and the future of digital resilience.
A demo-driven and thought-provoking speaker, Alexius has presented at Devoxx Morocco, JCrete, Voxxed Days Luxembourg, Open Conf, and many others. Beyond the stage, he is a GitKraken Ambassador, a board member of AHEPA Paris, and a member of AICatalyst. As founder and administrator of Greece’s largest developers and designers community with over 18,000 members, he brings clarity, energy, and a rare cross-disciplinary perspective everywhere he goes.
 
 
His Speech is: The Dark Side of IT: Green Cloud Hypocrisy and the Thirst of AI [Tech with Impact]
 
#Sustainability, #Green Computing, #Artificial Intelligence, #SLMs, #Leadership, #Cloud Computing, #Edge Computing

Corporate boards push IT directors to adopt green computing strategies. At the same time, they demand the immediate integration of artificial intelligence into every business process. These two goals collide. We ask for green operations while deploying the most resource heavy technology in history.
In the past, resource optimization was a matter of survival. Programmers counted every byte. Today, we burn megawatts of power and consume millions of liters of drinking water to make a large language model write a simple email. This is not innovation. This is computational arrogance.

This speech exposes the dark secret of AI water consumption and the creative carbon accounting of big cloud providers. It offers a practical path forward for IT leaders. We will discuss how to question the necessity of massive AI models. We will explore the shift toward small language models and the return to edge computing. True green computing means writing efficient code and choosing the right tool for the job. Join me to explore how we can restore engineering discipline and build sustainable software.

Embracing Chaos: Harnessing the Power of Chaos Testing for Resilient Systems

  • Testing is essential to ensure that your software application performs as expected. No doubt about it. But even if your application runs smoothly in a testing environment, unexpected incidents can occur in production, such as a crashed database or a lost connection to a third-party service. To ensure your application can handle such incidents and minimize their impact, you need to incorporate chaos testing into your delivery process. In this workshop, we will start with a brief introduction to k6 for backend performance testing and we’ll explore how to implement chaos testing using k6 for two backend services, to help you ensure the resilience of your application.

Liberate your data using Redis Stream and Go

  • Redis is an in-memory database popular for many use cases, such as content caching, session stores, real-time analytics, message broker and data stream needs. Since version 5.0 of Redis a new data structure, Redis Streams, dedicated to managing streams has been introduced. Using Redis Streams, anyone can do a lot more than what was possible with Pub/Sub, Lists or Sorted Sets in the data stream domain. In this all-hands session, we’ll walk you through the basics of how to use Redis Streams, how consumer groups work, and finally show a working application using Go that uses Redis Streams.
