Worked on the meshtastic/firmware repository to expand and standardize the emoji and emote subsystem for embedded devices. Focused on optimizing memory usage by refactoring all emote and emoji assets to a consistent 16x16 pixel format, implementing new icons as PROGMEM byte arrays to minimize RAM consumption. Used C++ and embedded systems programming to deliver new features, including additional emotes and improved asset management, while maintaining code hygiene and documentation. Prioritized UI consistency and efficient rendering on constrained hardware, enabling richer user interactions without increasing runtime memory footprint. Demonstrated attention to maintainability and teamwork through collaborative code contributions.

Dec 1, 2025Month: 2025-12 — Firmware work focused on emoji asset optimization for meshtastic/firmware. Delivered standardization of the emoji library to 16x16 pixels, expanded the emoji set with new emotes, and refined memory usage to suit constrained hardware. Implemented a comprehensive refactor of emoji assets across emotes.h and emotes.cpp, adding new bitmaps and ensuring consistent rendering. Addressed a minor code hygiene issue (missing newline at end of emotes.cpp) to improve maintainability. Result: improved UI consistency, reduced memory footprint for emoji assets, and support for richer user interactions without increasing RAM usage.
