[3] She has also previously worked in mixed martial arts sports journalism and was an editor for Sweden's official website Sweden.se.

[6] She studied engineering physics at the Royal Institute of Technology (Kungliga Tekniska Högskolan), a research university in Stockholm, Sweden, but dropped out after a year.

[7] She started creating self-described "shitty" inventions after studying at Hyper Island in Stockholm, where she was inspired by the local open-source hardware community.

[7] Giertz has previously branded herself as "the queen of shitty robots" on her YouTube channel, where she employs deadpan humor to demonstrate mechanical robots of her own creation to automate everyday tasks; despite working from a purely mechanical standpoint, they often fall short of practical usefulness, for comic effect.

[7] When building her robots, Giertz would often not aim to make something useful, instead coming up with excessive solutions to potentially automatable situations.

[15][16][17] Around this time Giertz had abandoned the concept of the "shitty robots", later explaining that it was no longer something she wanted to do, as she felt that the joke had played out.

[19] In June 2019, Giertz announced that she and various other YouTube makers, including Laura Kampf, had converted a Tesla Model 3 into a pickup truck.

The accompanying parody commercial and 31-minute video describing the build process went viral and received significant news coverage.

[36] After a course of radiation treatments, Giertz again returned to production on May 29, 2019, describing her ordeal and presenting a project which converted her head alignment mask into a "work of art" (a lamp).
