A little about me.
I'm Jan Hrnek and I study mechanical design engineering at the Faculty of Mechanical Engineering, Brno University of Technology. Alongside school I work freelance — design, calculations and drawings for companies that need something built from scratch.
I've been around mechanical engineering for over five years, from technical secondary school through two internships at Voith Turbo to the jobs I now run on my own. What I like most are projects where mechanics meets electronics and code — that's where you learn the most, because no part of it can be fudged.
When I'm not modelling, you'll find me playing volleyball, at the computer or travelling. And every so often I build myself a tool — an app for invoicing and part numbering, because doing it by hand annoyed me.

How I got here.
Schools, jobs and projects in the order they happened. Some entries carry a few words on what they gave me — those open up.
The start

SOLIDWORKS certificationsCSWA and CSWP

What backs it up.
Two SOLIDWORKS certifications from Dassault Systèmes, both taken in January 2024 as an academic exam at technical secondary school. You can open each certificate and verify its code with Dassault Systèmes.
CSWP is the higher of the two common levels Dassault Systèmes awards for SOLIDWORKS. It says nothing about structural analysis or professional certification — that needs a chartered engineer, which I am not. It says I can work in SOLIDWORKS at a professional level, including reworking a design as the brief changes.
