— Data Sanity Talks Belgrade Oct 4: A talk recording —

Here is one talk that we forgot to post saved for last!

🎙 Launching AI in Conservative Corporations: Turning Skepticism into Value

Speaker: Mariya Zlenko, AI Product Director @ Uralsib

Mariya shares her experience of bringing AI to a place where people are sceptical about the new technology, and what she learned along the way.

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!

Data Sanity Workshop: Optimizing AI Agent Prompts with DSPy

🗓 December 20, 11:00 - 13:00
📍 Belgrade, Nušićeva 15
🎟 https://luma.com/xi58ggeo

​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

✒️ Register for free to secure your spot!

🚨 OpenTalks.AI: Last call for speakers!

Today is the final day to submit a talk proposal for OpenTalks.AI, an ML conference happening in Belgrade on Feb 19-20.

Yes, it’s a very late notice — but there’s still time!

Apply here: https://opentalks.ai/en/call-for-proposals

P.S. We, the Data Sanity team, are also planning our own event on the weekend following the conference — stay tuned!

Fellow data scientists and enthusiasts,

We, the Data Sanity team, are preparing a course on LLM and AI agent basics — covering both theory and practice (Python + LangChain & LangGraph ecosystem). We'll teach you fundamentals and more advanced topics, highlight main trends in the industry, and help you build an AI agent to practice your newly acquired skills.

We'll host 8-9 in-person seminars in Belgrade in March and April. But when exactly? You can help us decide by voting in the questionnaire below!

P.S. We are currently looking for a sponsor to make this course 100% free. If you'd like to sponsor and help the local data community — please reach out!

Hello data fellows,

OpenTalks.AI conference program is live!

The OpenTalks.AI 2026 conference will take place on Feb 19-20 at Sava Centar. There will be 3 tracks — research, engineering, and business — with hot topics like LLMs, CV, AI agents, compute optimization, and more!

Fellow data scientists and enthusiasts,

Data Sanity is launching the course "Intro to AI Agents" — 8 sessions combining lectures and workshops on AI agent development.

🗓 When: Saturday 11:00 — 13:00, March 21 — May 23
📍 Where: Belgrade, Faculty of Mathematics, Studentski trg 16
🖊 Register by March 8: https://forms.gle/gTZD3ZsQXrAvKjDr7

The course covers LLM and AI agent fundamentals, modern agentic frameworks, and hands-on exercises for building AI-powered tools — plus a collaborative project guided by an experienced mentor!

You'll learn:
🚀 Design efficient prompts for LLMs
🚀 Build RAG pipelines and LLM-based agents
🚀 Prototype complex AI pipelines with LangChain and LangGraph
🚀 Evaluate, optimize, and deploy agentic applications

Registration: The course is open for both university students and external participants, including working professionals. It is 100% free, but the number of seats is limited. To apply, please register by March 8, 23:59 CET.

Details: https://datasanity.dev/intro-to-ai-agents-belgrade-2026.html

This course is developed in collaboration with AI Future Hub, and hosted by the Faculty of Mathematics (Matematički fakultet), University of Belgrade.

We've already received 40+ submissions — we're very excited that this initiative has attracted attention in the community!

A few common questions we've received:

Q. Why is this course free?
A. The Faculty of Mathematics is generously hosting us at no cost, and we wanted to pass that on — so there's no fee for participants.

Q. Is this course only for students?
A. No, it's open to both students and professionals. We believe that mixing people with different background is beneficial for everyone.

Q. Will the sessions be recorded?
A. Yes, although it's mainly for participants who missed a session to be able to catch up. It's best to attend in person.

If you're interested — register by March 8! Registering early helps us plan and may mean faster approval.
