I build embedded Linux Firmware that ships. Recent work on Upwork: • OpenWRT firmware for an 802.11s mesh + audio-over-IP product: 491 hours, sole developer of the codebase, 5-star review. • Yocto A/B partitioning, U-Boot, and SWUpdate OTA updates for an embedded Linux device: 166 hours. • BLE audio capture + Whisper + Gemma speech pipeline, delivered over a weekend. • Raspberry Pi / Arducam 64MP imaging system with AWS and AI integration. Where I help most: • Embedded Linux: OpenWRT, Yocto/BitBake, U-Boot, kernel and Wi-Fi driver patches, OTA updates • Firmware and C/C++ on SBCs, Raspberry Pi, Zynq/FPGA • RF and wireless: Wi-Fi mesh/MANET, LTE, Bluetooth, RF test and measurement • Hardware bring-up: schematic review, PCB design, lab debugging with scopes and spectrum analyzers • Edge AI and computer vision prototypes
