During June 2025, this developer focused on integrating Heatshrink-based data compression into the Phoenix-RTOS ecosystem, working across the phoenix-rtos-ports and phoenix-rtos-project repositories. They implemented build system changes and updated submodules to introduce the Heatshrink compression library, enabling data compression capabilities and preparing the groundwork for future compression-enabled features. Their work included adding a dedicated build script, integrating the library into the ports list, and enabling IA32 build support for Heatshrink. Utilizing shell scripting and build system integration skills, they improved build reproducibility and cross-platform readiness, supporting future runtime compression workflows within the Phoenix-RTOS project infrastructure.
