I'm a software engineer and independent developer with a focus on building practical, user-facing tools — from ServiceNow automation and developer utilities to full-stack web apps and open-source experiments.
I enjoy turning technical curiosity into something tangible and useful.
Global web app helping travelers and locals find nearby public toilets quickly and reliably.
The idea came after a friend from Asia pointed out how surprisingly few public toilets there are in many European cities — and how hard it can be to find one when seconds count.
Built with Next.js, MapLibre GL, and OpenStreetMap data.
Focuses on speed, clarity, and a clean UX.
A sophisticated decision-support tool for Real Estate investors in the Czech Republic.
It helps measure the "opportunity cost" of capital by comparing a leveraged property investment against a compounding market portfolio (S&P 500 / All-World ETF).
Why it matters:
Most generic calculators ignore the specifics of the Czech market. This tool includes:
- Czech Tax Optimization: Built-in support for the "Time Test" (tax exemption after 5/10 years) and mortgage interest tax deductions.
- Leverage Squeeze: Calculates the exact "Dead Equity Trap" point — when the Return on Equity (ROE) of the property drops below the market benchmark.
- Sell vs. Hold Strategy: Dynamic projection of future Net Worth for both strategies over 30 years.
Built with Python & Streamlit. Completely vibe-coded and potentially broken.

TypeScript-based tools for ServiceNow.
A toolkit designed to make development with ServiceNow APIs more reliable, type-safe, and developer-friendly.
Platform-independent command-line interface for ServiceNow, written in Python.
Allows developers and admins to execute local scripts on remote ServiceNow instances directly from the terminal.
(Supersedes the original SnowRun project.)
A web dashboard for the Sacred machine-learning experiment management framework.
Used to monitor, compare, and visualize experiment runs — simplifying ML experiment tracking long before tools like Weights & Biases became popular.
Experimental implementation of a subset of Pascal using Oracle Labs’ Truffle framework.
Inspired by the original Pascal language from Niklaus Wirth (ETH Zürich), exploring compiler construction and language runtime design.
A simple library for evolutionary computation, developed as part of a course at the Czech Technical University.
Supports evolving fixed-length binary genomes and basic selection/crossover/mutation mechanisms.
“Curiosity-driven development: building things that should exist, even if nobody asked for them.”
