Jelle De Laender
TLDR
Jelle De Laender is founder and CEO of Semonto, a Belgian website and server monitoring service he built after getting frustrated by unreliable hosting while still a student at Ghent University.
Overview
Jelle started coding at age 14 and founded Coding Mammoth in 2007 while still studying at the University of Ghent. He created Semonto as an internal tool to alert him when servers went offline, and it grew over 12 years into his most popular product.
Beyond Semonto he has worked as a security leader at Sketch and is interested in security research, AWS cloud hosting, and 3D printing. Semonto is a European-hosted alternative to US monitoring tools, used by organisations including De Lijn.
