Tavis contributed to the meshtastic/firmware and Meshtastic-Android repositories by building robust telemetry and scheduling features while addressing critical stability issues. He developed a configurable periodic task runner in C++ for firmware, enabling scheduled execution of user-defined code with minimal runtime overhead. Tavis also expanded telemetry parsing to support multiple weather sensor models, improving data reliability for environmental metrics. On the Android side, he enhanced Bluetooth connectivity by handling edge-case disconnections, reducing device downtime. His work demonstrated depth in embedded systems, concurrency, and data parsing, with careful attention to code safety, modularity, and traceability across both firmware and mobile platforms.
April 2025: Delivered a configurable periodic task runner (GenericThreadModule) in firmware to execute user-defined code at fixed intervals. The module is build-flag configurable to exclude from builds when unused and includes basic logging for initialization and execution. This feature enhances scheduling flexibility, reduces runtime overhead when disabled, and provides a foundation for future automation and modular task management in the firmware. Commits: e7ce910c3b6613ca50ce8133e3998758c3f07eaa (Add generic thread module (#5484)).

March 2025 (meshtastic/firmware): Focused on expanding telemetry parsing to support multiple device models and richer environment metrics. Delivered a multi-model weather data parser with rain data support for WS85 (1h and 24h) and WS80 compatibility, enabling unified reporting of wind, voltage, temperature, and rain. This work paves the way for cross-model analytics and improves telemetry reliability.

November 2024 firmware work on meshtastic/firmware focused on telemetry data correctness. Delivered a targeted bug fix that ensures relative humidity data presence is accurately reported when multiple sensors are combined. Specifically, the has_relative_humidity flag from AHTX0 telemetry is now correctly copied into the main telemetry packet in combined sensor setups. This patch is minimal-risk with commit aa184e6d8b6ef75fbb122f0c00dbfceeb89b4e59 (linked to #5277). Impact: improved data accuracy for downstream analytics and alerts, reduced debugging effort, and increased user trust. Technologies/skills demonstrated: embedded C/C++, telemetry data modeling and integration, sensor telemetry pipelines, code review, and targeted debugging.
