Curious about how AI applications can go beyond simple chatbots? On **Thursday 10/04** at **fromScratch Studio HQ** in **Thessaloniki**, we’ll dive into **practical AI development**—showcasing how **Python, Ollama, LangChain,** and **Retrieval-Augmented Generation (RAG)** can be used to build real-world AI applications.

In this hands-on session, **Dimos Homatas** will guide you through key concepts, tools, and workflows that enable AI-powered solutions, **all while building a personal AI-powered photo library**. Along the way, you’ll learn:

* How to **run Large Language Models (LLMs) locally** with Ollama.
* How LangChain helps **orchestrate LLMs, agents,** and **tools** in Python.
* Why **vector databases** and **RAG (Retrieval-Augmented Generation)** are crucial for AI applications.
* How to **embed** and **search images** using AI.

**About the Speaker**

**Dimos Homatas** wrote his first lines of code at the age of 10, programming in **BASIC on an Amstrad CPC 6128**. Since then, he has worked across a wide range of domains—**from legacy systems to cutting-edge technologies**.

Currently, he is **SVP** at **WeAre8**, a social media platform, while staying true to his roots as a **tinkerer** and **hobbyist**, always exploring new personal projects. When he’s not coding, you’ll find him immersed in sci-fi books or headbanging to metal.

**What to Expect**

This **2-hour session** is designed for software engineers, data scientists, and AI enthusiasts who want to get hands-on with **modern AI development**. You’ll follow an **end-to-end process** while working in **Google Colab**, learning key concepts like vector search, document embeddings, and chunking.

💻 **A laptop is required for participation** as this will be an interactive, code-along session.
🖼️ **Participants must bring a collection of personal (or not) photos** (at least 15) to use during the hands-on exercises.

By the end, you’ll have built your **own AI-powered photo search tool** and gained **practical skills** for working with LLMs beyond chatbot applications.

🍻 **Stick around after the event for networking over beers!** This is a great opportunity to connect with fellow AI enthusiasts, exchange ideas, and discuss what you've learned.

**Who Should Attend**

This event is for anyone interested in the real-world application of AI—whether you’re a professional, student, or AI enthusiast. Bring your curiosity, and your laptop with some basic Python knowledge, to dive into hands-on experiments.

**Registration**

We will meet from **7:00 PM** to **9:00 PM** at **fromScratch HQ** (Themistokli Sofouli 70Α). Don’t forget to RSVP to secure your spot!

**Please note that all presentations and discussions will be conducted in Greek.**

We look forward to seeing you there and exploring the world of AI together!
