HOW I THINK.
- 01
SYSTEMS THINKING
Relationships, interfaces and feedback loops before isolated parts.
- 02
ANALYTICAL REASONING
Turning ambiguity into assumptions, constraints and testable decisions.
- 03
PROBLEM DECOMPOSITION
Breaking complex systems down without losing the full operating context.
- 04
CONCEPT ARCHITECTURE
Building the mental model before committing to tools or implementation.
APPLIED 05 / SOFTWARE + AI
THE BEHAVIOR LAYER.
APPLIED 01 / MECHANICAL DESIGN
CAD THAT HAS TO FIT.
Parts, tolerances and assemblies modelled for the physical world.
APPLIED 02 / ELECTRONICS
FROM SIGNAL TO PCB.
Schematics, layout and hardware that turn a signal into a reliable circuit.
APPLIED 03 / PROTOTYPING
BUILD. MEASURE. REPEAT.
3D printing, fabrication and fast physical iterations at real scale.
APPLIED 04 / MECHATRONICS
ONE SYSTEM. ONE LOOP.
Mechanics, sensors, control and motion working as one autonomous machine.

PROFILE / PJE
I build the whole loop — from physical input to useful software.
Trained as a mechatronics engineer in automation technology. I design PCBs, work in CAD, prototype fast, and build the software and control systems around it.
Start with the smallest useful version. Keep the system understandable. Make it stronger where real use proves it matters.
