## Summary

Plan A was to be a professional hockey player my whole life. I ended up somewhere else.

Pro hockey until 28 (#86, HC Zubr Přerov). Two years selling cars at a Škoda dealership. Then I taught myself to code, and since 2019 I've been building the core of Disivo, a dynamic pricing SaaS. I also design, build and ship my own iOS apps.

## Career

- **Until 28 — Professional hockey.** Plan A. #86, HC Zubr Přerov.
- **2017–2019 — Selling Škodas.** Two years at a dealership. Learned how to deal with people.
- **2019 → now — Software engineer at Disivo.** The core of Disivo's dynamic pricing platform. Plus my own iOS apps on the side.

## Work (production systems at Disivo)

### Pricing engine
- Stack: Rails, PostgreSQL, Elasticsearch, Redis
- Built and maintain the core of Disivo's dynamic pricing platform: the engine that turns competitor data into prices for online stores.
- Impact: used by roughly a third of Czech e-commerce.

### Scraper without a browser
- Stack: HTTP + parsing, proxies
- Headless rendering was slow and expensive. I built a scraper API on plain HTTP requests and parsing, running in production next to the old system, so a new source goes live fast.
- Impact: 0 headless browsers.

### Zora
- Stack: LLM extraction, RAG
- A production LLM extraction pipeline, not a demo. Next-generation scraping of a million products per day.
- Impact: 1M products per day.

## Skills

I like building web apps that stay clean as they grow, and putting LLMs to work on real business problems. Six years in production taught me to own things end to end, from the scraper that collects the data to the price that goes live.

- **Full-stack — Web apps built to last.** Ruby on Rails, Hotwire, PostgreSQL, Elasticsearch, Redis. Boring tech, used well.
- **GenAI & LLMs — AI that ships.** Extraction pipelines, RAG and LLM features that run in production behind a queue, not in a notebook.
- **Data at scale — Messy data, tamed.** Large-scale scraping and pricing data for roughly a third of Czech e-commerce.
- **Versatility — Quick to pivot.** Hockey, then sales, then software. After that, picking up a new stack is the easy part.

## iOS apps (solo projects)

- **Skycatching** — Collect the real stars above you tonight, based on where you stand and when. Live on the App Store: https://apps.apple.com/cz/app/skycatching/id6808668776
- **Homeborn** — Documenting a house build from the foundations up. Made while building my own. Live on the App Store: https://homeborn.app
- **Filvy** (retired) — A family document vault. Designed, built and shipped alone, then stopped: Apple made the idea native with OCR search across scanned documents and photos. https://filvy.app
