During April 2026, Stef Helling focused on enhancing the reliability of timer scheduling within the philips-software/amp-embedded-infra-lib repository. He addressed a critical issue in the Timer Service by fixing a bug that previously prevented correct recomputation of the next trigger time when a timer was updated to an earlier value. Stef reinforced this solution by developing targeted unit tests in C++ to capture the failing scenario and guard against future regressions. His work demonstrated a strong grasp of embedded systems and test-driven development, resulting in improved scheduling accuracy and robustness for time-sensitive operations within the library’s infrastructure.
