System Architect · Eindhoven, Netherlands
I map complex systems fast, then break them into pieces your team can actually ship.
Twenty years across software, electronics and hardware — the messy space between firmware and cloud, between what's technically elegant and what a customer will actually pay for. I've written the slicer and the machine firmware for the same 3D printer, and built a scanning electron microscope in my workshop.

Six layers · one engineerMost architects own one band of this stack. The value is in the seams — so here is every layer I've shipped in, and the thing that proves it.
Things I built
Public · verifiableInstrumentation
Scanning electron microscope
Electron optics, high vacuum, high voltage and precision machining — designed, simulated and machined at home. Custom scan-signal board with ground-plane shielding to keep crosstalk off the beam.

Engineering software
Oblikovati — MCAD from scratch
History-based parametric CAD targeting parity with Inventor, SolidWorks and NX. Own geometry kernel, own renderer, and add-in bridges to CalculiX, Elmer, GetDP and FEMM so structural, thermal and electromagnetic analysis share one model.

Mechatronics
Dual-axis solar tracker
Closed-loop tracking using an accelerometer as absolute angle reference, with shadow compensation, hardware end-of-travel interlocks and anemometer-driven wind stow. Measured 14.22 → 16.41 kWh on a clear day.

Tooling
BLDC motor sizing calculator
An interactive tool for sizing brushless motors — working through torque, winding and magnetic circuit trade-offs in the browser, backed by FEA magnetics.

Track record
Most recent firstSolution Architect & Technical Lead — Avanade
Enterprise architecture for major European companies. AI model-serving platform for a top-3 Dutch bank; led a heating manufacturer's move from waterfall monolith to modular services, cutting codebase size by 70% and closing critical vulnerabilities.
Product Security Engineer — BD Rowa, medical automation
First hire on a new product security function at a pharmacy-automation manufacturer, clearing decades of debt that was blocking North American market entry. Static analysis and vulnerability scanning across 1M+ lines within two months, with no disruption to the release cycle.
Co-founder & CTO — CNC Brasil, industrial 3D printers
Principal engineer across mechanical design, electronics and software. Wrote the slicer, modified the machine firmware in C, architected the fleet health-monitoring platform. Sole developer at the start; led the engineering team by the end.
Product Engineer — Ledmidia, LED display hardware
Designed a high-data-rate panel interface from low-cost TTL logic to hit a hard cost ceiling, delivered in six months. The cost budget drove the architecture, not the performance ceiling.
