Lewis He developed and enhanced embedded firmware and board support packages for the meshtastic/firmware and espressif/arduino-esp32 repositories, focusing on hardware integration and power management for devices like the T-Deck, LilyGo T-LoRa-Pager, and T-Watch-S3-Ultra. He implemented early peripheral power enablement to stabilize boot-time voltage, introduced pin-based modem control to reduce startup power consumption, and updated board definitions and partition schemes to support new hardware variants. Working primarily in C++ and Arduino, Lewis demonstrated depth in embedded systems and hardware configuration, delivering features that improved device reliability, compatibility, and integration for both end users and downstream developers.
In August 2025, delivered a power-efficient modem control feature for the firmware repository, introducing default modem disable on startup and pin-based control to reduce startup power consumption and prevent unintended modem activity on the T-Deck-Pro 4G devices.

December 2024 focused on stabilizing boot-time power for T-Deck devices to improve reliability and user experience. Implemented early peripheral power enablement to prevent low-voltage resets during startup, by energizing keyboard, audio amplifier, and display backlight earlier in the boot sequence. This targeted fix in meshtastic/firmware reduces startup voltage fluctuations and enhances device stability for T-Deck hardware. The work supports ongoing power-management improvements and is expected to reduce field incidents linked to boot-time power demand.
