About this Gig

Welcome!

I write deterministic embedded C/C++ wireless firmware for low-power IoT networks, custom mesh topology, and reliable gateway bridging. Zero blocking loops or memory leaksevery stack is architected for low current draw and rock-solid packet recovery.

Wireless Stacks:

LoRa/SX1262, nRF52 BLE Mesh, Zigbee
ESP32, STM32WB, Nordic nRF52840
MQTT-SN, CoAP, UART/SPI drivers
Sub-microamp sleep & RTC wake

You Receive: Firmware binary, documented source code, and OTA update script.

Bad mesh handoffs drop packets, high sleep current drains batteries, and memory leaks crash remote nodes. You need firmware that self-heals and runs for years on a single cell.

Stop risking field deployments on buggy code. Send your radio spec and strict power budget nowlet's flash your network today!
