Jeff Geerling is an American author, open-source software developer, and hardware reviewer best known for his YouTube channel.

Career

[edit]

Geerling has worked as a web developer,[1] beginning his career building a website that displayed song titles and artists for radio station KYKY for his father.[2][3] He is also an author of books on Ansible and Kubernetes.[4][5][6]

YouTube

[edit]

Geerling became a full-time content creator in 2021 for his self titled Jeff Geerling YouTube channel, focusing on single-board computers, software programming, and electronics[7] and supported by sponsorships and Patreon members.[8] In particular, he has become recognized for his various projects using Raspberry Pi computers[2] with very large storage arrays,[9] high-performance compute,[10] clusters,[11][12][13] and external GPUs.[14][15]

Geerling later started a second YouTube channel Geerling Engineering to discuss radio engineering[3][16] with his father, who is a radio engineer.[17]

In 2024, Geerling received attention after noticing his voice was cloned without consent by the electronics manufacturer Elecrow,[7][18][19] and the company subsequently apologized and removed the offending content.[20] Geerling's experience was cited as a case meant to be addressed by YouTube's likeness-detection technology when it was released in 2025.[21][22]

Personal life

[edit]

Geerling intended to become a priest,[23] attending at St. Louis University and Kenrick–Glennon Seminary,[24] before leaving the seminary to get married.[23] As of 2024, he is married and has children.[7]

Geerling was diagnosed with Crohn's disease[25] and had ileostomy surgery in 2018 to treat it.[26] He subsequently wrote a book about life with the disease.[27]
