Areas of Expertise
Four disciplines, one perspective
My career has spanned fields that look unrelated on paper. Today I build products exactly where they intersect — because a developer who knows the industry does not have to wait for someone else to describe the problem.
Dangerous Goods (DGSA)
Safety advisory for air and road transport of dangerous goods, including work at FedEx Express — regulation, compliance and operations.
- ADR
- IATA DGR
- Compliance
- Audit
Software Development
Web and mobile development, API design and software testing. I do not just write the product — I test it and ship it.

- Mobile
- Backend

Entrepreneurship
Since founding my software company in 2026 I build my own products, running the whole cycle from idea to release on my own.

About Me
From engineering to logistics,
From engineering to logistics,
from logistics to software
I started my professional 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 of dangerous goods at several organisations, including FedEx Express, applying ADR and IATA DGR regulations 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. So I started building that capability: I studied Computer Programming and earned certifications in software development and testing to put a proper technical foundation under the practice.
In 2026 I founded my own software company. I now develop products that bring together dangerous goods safety, logistics, transport and software technology — using both my industry experience and my engineering skills to ship my own products.
