# Šimon Podhajský – AI, Data & LLM Practitioner

> Prague-based consultant turning cutting-edge AI and data engineering into reliable production systems.

## Biography

Lapsed neuroscience researcher (at Yale and SRI) turned AI & data engineer and occasional independent consultant. Working at Waypoint AI as a Lead AI/Data Engineer as of May 2025. Previously worked at Pure Storage (2024) and Nano Energies (2023).

Educational background: Cognitive Science at Yale, International Baccalaureate at Open Gate Boarding School. I got into both because I excelled at tests and debate competitions.

Based in Prague, Czech Republic.

I build production-grade LLM workflows, teach for Czechitas, and host the *Data Talk* podcast. I'm also a board member of [Asociace debatních klubů](https://www.debatovani.cz/).

Primary focus: LLM evaluation pipelines, retrieval-augmented generation and MLOps.

Historical focus: building reproducible research/production pipelines with dbt, Python, and whatever else the task required.

## Significance

* **Community voice** — talks at EuroPython, AI Tinkerers Prague, World Data Congress ’23  
* **Early LLM tooling adopter** — field notes on AutoGen, LangGraph, Langfuse, DeepEval  
* **Open demos** — side-projects like *Cover Letter Automation* showcase pragmatic multi-agent design

## Openness to offers

I'm open to speaking engagements, workshops, and other events.

I'm also available for **one-time, short-term or weekend consulting** with high impact and learning potential.

Typical engagements:

* LLM evaluation & prompt engineering  
* Retrieval-augmented generation architectures  
* Data-to-AI infrastructure (dbt, Airflow, DuckDB, Langfuse)
