Sergio Gutierrez

I am a physicist by training. I studied light: entangled photons in Bogotá, then machine learning on optical fibre in Lund. Since 2020 I have worked at Ericsson, from digital pre-distortion and ASICs to leading 6G prototypes. In my own time I build software tools and small devices, and write down what I learn.

A personal site. Views are my own, not my employer's.

01 What I learned where

  • Physics

    Curiosity, and order: a clear concept, a careful attempt, an honest assessment, then another try. In the lab you can see the light, put a crystal in the beam and measure what comes out with your own hands.

  • Industry

    Execution: holding a technical intent for years and getting it into silicon, through work packages, people, measurements, supply and budget. At work I orchestrate rather than build alone.

  • My own time

    Building by hand again: software tools, small devices and machine-learning experiments.

02 Career

6G Prototype Technical Lead, Ericsson, since 2024-12. At Ericsson in Malmö since 2020.
