Physicist by training, engineer by trade. This is where I run my own experiments.

I studied light: entangled photons in Colombia, then fibre optics and machine learning in Lund. Since 2020 I have worked at Ericsson, from digital pre-distortion and ASICs to 6G prototypes. This site is for what I build in my own time: machine-learning projects, small devices, and notes on how I work.

“Nothing is too wonderful to be true, if it be consistent with the laws of nature; and in such things as these, experiment is the best test of such consistency.”
