PROFILE

Błażej Sowa

Over a three-month period, Bartosz Sowa enhanced embedded systems and build infrastructure across eclipse-zenoh/zenoh-pico and NixOS/nixpkgs. He implemented precise timekeeping in the zenoh-pico mbed port by integrating the Mbed Platform Clock API using C and C++, enabling accurate scheduling and logging. Bartosz also improved cross-RTOS synchronization by refactoring condition variables and mutexes, introducing timed waits and static allocation to increase reliability in resource-constrained environments. In NixOS/nixpkgs, he addressed build system compatibility by updating schroot’s CMake requirements, ensuring smoother packaging and toolchain upgrades. His work demonstrated depth in system programming, concurrency, and package management.

November 2024: Eclipse Zenoh Pico (eclipse-zenoh/zenoh-pico) delivered a critical platform enhancement by implementing the Mbed Platform Clock API in the mbed port. This included introducing z_clock_t and functions to obtain current time and elapsed time in microseconds, milliseconds, and seconds via the mbed OS Kernel::Clock API, enabling precise timekeeping across the port.
