Summary
🤩
Rockstar🎓
Top SchoolLotte Steenbrink is a Hamburg-based embedded systems engineer and freelancer with 15 years of experience designing reliable IoT and networking software. She has held senior roles at Ferrous Systems and Zühlke and contributed to industry projects like RIOT-OS, improving documentation, examples, and tests to make embedded tooling more accessible. On GitHub she enhanced knurling-rs/defmt—adding nuanced support for booleans, strings, slices, floats, bitfields and extra log levels—demonstrating attention to efficient, low-overhead logging for constrained devices. Her background includes academic research on MAC and reactive routing protocols (IEEE 802.15.4e, AODVv2) and a practical internship at Airbus where she compressed routing messages to enable low-bandwidth operation. Lotte combines rigorous research experience with hands-on embedded development and a knack for turning protocol-level insight into pragmatic, test-covered implementations.
