I am a security researcher and a software engineer. I like researching about whatever I find interesting. So just look around and see what I do.

A real kernel, in your tab.

03 · SECURE DOCUMENT
Break it, learn it, build it.
Every project is issued as a security note: guilloché, microprint, a foil strip and a serial number. Your cursor is a UV lamp. Shine it on a note to see the hidden ink.

04 · DAGUERREOTYPE
Anything else I do that no one cares about.
Silver mirror plates, 1839 style. A daguerreotype only shows a positive image at the right angle. Move the light (cursor, or tilt your phone) and each plate flips from negative to positive.
05 · FERROFLUID
Tools and languages I use (know and partially know)
Three pools of magnetic fluid on a steel plate. Your cursor is the magnet. Hover a tool and the fluid spikes toward it.

06 · LASER ENGRAVING
The part where I tell you what I've done.
Laser-etched into brushed steel. The light follows your cursor, or your phone's tilt.
