P.S. We are about to announce two events in December — a seminar in Novi Sad and a workshop in Belgrade. Stay tuned!

🚀 One Seminar — Two Topics to dive in with Vadim Opolski (Senior Data Engineer @ DXC)!

📍 Novi Sad, Startit Centar
🗓 December 13, Saturday | 11:00 - 13:00
✒️ Register here! (free)

​At this seminar, Vadim will guide us through two interconnected storylines, each uncovering a different side of modern engineering:

​⚡️ Topic 1 — Architecture Problems and Solutions in Streaming AI Pipelines
Vadim will break down a production-grade streaming architecture for monitoring text, photos, and video using Spark and Kafka — highlighting pitfalls, design decisions, and practical solutions.

​⚡️Topic 2 — From TDD to SDD with AI Agents We’ll explore how Test-Driven Development is evolving into Spec-Driven Development with AI tools. Together we’ll test agents live, generate specs, create architecture and tests automatically, build a working prototype from scratch.

​For those who want to try everything live during the session, please make sure you have:
1. ​Any console-based AI agent installed (e.g., Claude Code, GitHub Copilot).
2. ​The SDD tool spec-kit: https://github.com/github/spec-kit.

​One seminar, two topics — both hands-on and packed with insights!

ℹ️ Novi Sad | Dec 13 | Free registration

The Data Sanity seminar in Novi Sad is already tomorrow!

​In this hands-on workshop, you’ll be introduced to DSPy, a practical framework for optimizing prompts for AI agents.

Together with Michael Pavlukhin, we will:
🚀 Revisit the fundamentals of AI agents
🚀 Learn how to improve prompts using the GEPA evolutionary optimizer with DSPy
🚀 Build a movie recommendation agent
🚀 Experiment and gain hands-on experience

​Requirements:
🤖 A laptop
🤖 Proficiency in Python and notebooks
🤖 (Nice to have) Experience working with LLMs via APIs

✒️ Register for free to secure your spot!

​This event is hosted by Mainstream — the leading cloud provider in Southeast Europe.

The workshop begins in 24 hours!

A few tips:
❗️ Please register using your full name (required for lobby security)
💻 No prior experience with any specific LLM API is required
💻 We’ll be working in Google Collab, so there’s nothing to install ahead of time
💻 If you don’t have a laptop, you’re still welcome to attend and experiment with the notebook later at home
