I am a computer programmer and electronics engineer.

When I started programming back in 1993 on an 80386SX / 25 MHz machine, I used x86 assembly language and Object Pascal. As information was scarce, I learned mainly by trial and error and reading the help system of the development software. I learned strong design guidelines and solid architecture from computer literature of the era. This is the underlying stone on which I built all of my current knowledge.

I was always strongly driven to create minimalist functional graphical user interfaces to access the business logic behind my software. As for the source code, I went by the less is more principle. I produce heavily structured, self-explaining, ultra-optimized source code. Not a single line more than needed. I have been faithful to these principles ever since.

Although I worked with both CISC and RISC, I have always emphasized CISC and especially x86. Nostalgia? Maybe. I worked with various microcontrollers, Z80, and x86 microprocessors. Then I started designing my own computers, initially based on the Z80. But then I shifted to x86 system design. I designed a 32-bit 80386DX-based machine that I detailed within the Microelectronics sub-site.

In 1993, I also began assembling simple circuits based on schematics published in various electronics magazines. Then I started crafting my own. I am interested in analog audio signal amplification and digital microelectronics.

I regularly maintain projects tagged as active. Discontinued projects are displayed only for historical reasons and should be treated as archives.
