Summary
🤩
Rockstar🎓
Top SchoolLars Knudsen is an experienced embedded software engineer with 11+ years building firmware and mobile/web solutions across industries from medical training to consumer audio and shipping platforms. Currently at Oticon and running his own consultancy, he combines deep low-level skills (RTOS, BLE, Bluetooth Audio, LC3, PWM) with full-stack mobile/web pragmatism honed at Nokia and Maersk. A long-time contributor to the Zephyr RTOS—notably adding BLE/BAP and USB audio features—he blends hands-on kernel/driver work with practical debugging and tooling improvements. Lars is also an educator and builder off the clock, founding initiatives to teach mobile web development in Latin American high schools, reflecting a rare focus on local capacity building. His background in electronics, audio and creative projects (including early game and audio work) gives him a makers’ mindset that often pushes hardware beyond vendor expectations.
