About me

I started my career as a mining engineer and permanent site supervisor. Between 2015 and 2019 I worked in field operations in the mining industry, where I learned technical processes, occupational safety and what regulation actually means on the ground.

In 2019 I moved into dangerous goods safety advisory. I worked on air and road transport at several organisations, including FedEx Express, applying ADR and IATA DGR inside daily operations rather than only reading them.

Most of the problems I ran into in the field were, in fact, software problems. The day I realised that, I changed direction.

Recurring operational mistakes, lost paperwork and manual checks could largely be solved with software. I studied computer programming and earned certifications in software development and testing to build a proper technical foundation.

In 2026 I founded my own software company. Today I build products for dangerous goods, logistics and everyday life. I don't just write the product; I test it and ship it too.
