About this Gig

Need reliable firmware for your ESP32 IoT device? I'm a professional embedded software engineer with industrial experience in Linux drivers, bootloaders and low-level system bring-up. I build firmware with ESP-IDF and FreeRTOS that is stable in the field, not just a working demo.


What I can do:

Wi-Fi provisioning, reconnect logic and power-safe operation

MQTT, HTTP/REST and WebSocket cloud connectivity (AWS IoT, HiveMQ, Home Assistant)

BLE GATT services for mobile apps

Sensor and peripheral drivers: I2C, SPI, UART, ADC, PWM

OTA firmware updates

Deep sleep and battery-life optimization

Porting Arduino sketches to ESP-IDF

Debugging crashes, watchdog resets and memory leaks


Supported: ESP32, ESP32-S3, ESP32-C3, ESP32-C6

Tools: ESP-IDF, FreeRTOS, CMake, PlatformIO


What you get:

Full source code with build instructions

Code tested on real hardware

Short documentation of architecture and configuration


Please message me before ordering with your board and a short task description, so I can confirm scope and timeline.
