## About Me

I specialize in C++ and backend systems, with experience in computational geometry, performance optimization, legacy code modernization, production infrastructure, and technical leadership.

My approach has evolved from solving difficult technical problems to understanding which problems are worth solving, how to manage their risks, and how to help other engineers succeed.

## Work Experience

### Seznam.cz — Senior Software Engineer

08/2025 – present

C++, CMake, Conan, Linux, Docker, GitOps, Kubernetes, Aerospike, MariaDB, Argo CD, Git, Claude Code

- Owned several production database and service migrations in Seznam’s identity backend.
- Designed password storage that met new requirements and kept old passwords valid.
- Helping move deployments to Argo CD GitOps, C++ builds to CMake, and dependencies from Debian packages to Conan.
- Identifying hidden risks and assumptions in modernization proposals, and the cost of mitigating them, so the team can decide which to accept.

### Chyron — Senior Software Engineer → Technical Lead

03/2023 – 05/2025

C++14, C++/CLI, C\#, .NET Framework, Git, Windows, Visual Studio, Python, CMake, Conan, Jenkins, Jira, PostgreSQL

- Joined a new three-person team reviving an acquired ~10M-line broadcast weather suite, starting by restoring its build environment.
- Reconciled divergent customer-specific branches across five Git repositories, speeding development and helping ship customer-facing improvements alongside maintenance.
- Grew into the technical lead role, participated in hiring two engineers and an intern, and mentored teammates to lead increasingly complex projects.
- Proposed process experiments through which the team replaced fixed two-week sprints with a lightweight Kanban-style flow it found more efficient.

### TESCAN 3DIM — Software Developer

04/2021 – 03/2023

C++17, Qt 5, Linux, Windows, Visual Studio, CMake, Conan, Git, GitLab CI/CD, Redmine

- Developed and optimized robust 3D mesh Booleans and spatial queries in BlueSkyPlan dental planning.
- Moved heavy computation off the UI thread, substantially improving responsiveness.
- Introduced modern CMake and pioneered Conan so computation ran standalone on Linux for integration with a cloud platform.

### Brno University of Technology — Data Compression Researcher

06/2019 – 12/2020

C++20, CMake, Linux, Git

Designed and implemented a 4D-DCT light-field compression method in C++, building on the bachelor’s thesis, and coauthored two comparative papers.

## Education

### Brno University of Technology — Master’s in Computer Graphics and Interaction

2022
