Speaking.
I bring practical, experience-driven talks to conferences, meetups, and corporate events. 24 talks shipped to date — from AI Engineer Europe to dbt Coalesce to EuroPython. Whether your event is 30 people or 3,000.
What I talk about.
Evals & testing for AI
How to evaluate AI systems rigorously — synthetic data, automated testing, and continuous evaluation pipelines.
Data engineering
Modern data stacks, dbt, DuckDB, and bringing data engineering practices to small teams and startups.
Vibe coding
Running multiple AI coding agents in parallel; live demos of AI-first development workflows.
Python patterns
Pydantic, type safety, and practical Python patterns for the LLM era.

2026 Evaluace v praxi CERNA.AI (Ostrava, CZ) Všechny evals frameworky jsou tak trošku na nic. Jak je přesto využít? Moderní stack #7 (Ostrava, CZ) Jak poznat, že je AI co k čemu? Dobrodata (Prague, CZ)

Eval frameworks all promise more rigor than they deliver — but writing them off entirely is the wrong move. This talk covers what they actually get right, where they quietly mislead, and how to use them anyway to learn something true about your system. 30 Sep 2026 · register ↗
This talk deliberately isn't about what AI can do right now — that shifts again by Q3 — but about a harder problem: your own sense of productivity is unreliable, and a "good" result in one area says nothing about the one beside it. You'll leave with one question to ask constantly ("is this actually working for me?") and one concrete habit for answering it — finding your own pelican. 25 Nov 2026 · register ↗

"RAG is dead" is the take in every other thread in 2026 — and it's wrong: naive retrieval-augmented generation is still a sensible default, beaten only in some cases, and measurement is the only way to know if you're one of them. This talk walks the retrieval pipeline end to end, then turns to the part that matters — telling whether your RAG actually works, with ground truth, retrieval metrics, RAGAS, LLM-as-judge, and error analysis feeding an eval flywheel. Jun 2026
You need an eval set but don't have a hundred real production failures to build it from, so you reach for synthetic data — and most first attempts quietly produce garbage. A field guide to the techniques that actually work, from real-incident seeds to personas to RAG-grounded generation, with one throughline: synthetic data needs its own eval, so choose your technique backwards from the eval you want. Jun 2026
Using OpenClaw to build a Bayesian buy-vs-rent model for Prague real estate, and how to deploy something like that without setting your money on fire. Apr 2026
What happens when AI systems passively observe information without modifying it? Exploring the patterns and insights that read-only AI reveals — the cognitive byproducts humans overlook. Apr 2026
Most teams shipping GenAI products have no evaluation system. They have vibes, a few saved prompts, and hope. This talk starts with observability: if you can't see what's happening in production, nothing else matters. From there, we build the eval flywheel — a practical pattern where production observability feeds error analysis, error analysis generates eval cases, and eval cases prevent recurrence. Feb 2026
"I'll just write pytest tests for my LLM"—but should you? This talk untangles benchmarks, evals, and guardrails: three concepts that sound similar but map to different Python patterns. Learn why pytest CAN work for evals (with the right mindset), why guardrails aren't tests at all, and a grounded theory approach to defining what "good" actually means for your task.
Feb 2026
Most teams approach LLM evaluation like test-driven development: write tests first, then build. But LLMs have an infinite failure surface — you can't predict what will break. This talk argues for a different approach: deploy first, observe failures, then build evals for the patterns you've actually discovered. Feb 2026
