PROFILE

Leandro Lanzieri

Worked on embedded systems and hardware design, focusing on reliability and manufacturing readiness. Enhanced the RIOT LWM2M client in the qmk/RIOT repository by improving LWM2M URI handling and initialization, removing outdated documentation, and addressing a DTLS session resource management bug to reduce memory leaks and improve client stability. Utilized C programming and code cleanup techniques to boost maintainability. Later, updated the SenseMate PCB design in smartuni/riot-po-2025, refining Gerber file generation, through-hole component handling, and layout metadata for streamlined fabrication and traceability. Demonstrated expertise in C, KiCad, embedded systems, and documentation management across both software and hardware domains.

In November 2024, focused on strengthening the RIOT LWM2M client integration (qmk/RIOT). Delivered robust LWM2M URI handling with improved initialization via LWM2M_URI_RESET, removed legacy URI documentation, and performed targeted code quality fixes to improve readability and maintainability. Fixed a DTLS session resource management bug by destroying unused DTLS sessions in error paths, reducing memory leaks and boosting client stability. These changes collectively improve reliability in constrained devices, lower support costs, and set the stage for future resilience improvements. Technologies demonstrated include C, wakaama-based LWM2M, DTLS session lifecycle management, and code cleanup/refactoring.
