About this Gig
Need reliable ESP32 firmware that actually works in production?
I'm an embedded engineer with 10+ years of experience in ESP32, ESP8266, and embedded Linux. Unlike hobbyists, I write firmware that handles edge cases WiFi reconnection, power management, and memory leaks.
What I do best:
- WiFi + MQTT data logging to AWS IoT Core / AWS Kinesis
- Over-the-Air (OTA) firmware updates
- I2C, SPI, UART, BLE, CAN bus integration
- Deep sleep optimization for battery-powered devices
- Custom sensor drivers (temperature, pressure, IMU, GPS, etc.)
What you get:
- Full source code (ESP-IDF / Arduino / PlatformIO your choice)
- Test result report (PASS/FAIL for every feature)
- OTA update mechanism ready to deploy
- Clear documentation for your team
My guarantee: Your firmware will run 24/7 without crashing. If it doesn't, I fix it for free.

FAQ
What information do you need from me before starting?
A: I need a Requirements PDF or document detailing: Use-case / what the device should do Exact sensor part numbers (e.g., BME280, MPU6050) WiFi credentials (SSID, password, AWS endpoint if applicable) Any existing schematic or board photos
Which IDE or framework do you use?
A: I'm fluent in all three—ESP-IDF, Arduino, and PlatformIO. You tell me which one your team prefers, and I'll use it.
What happens if the firmware has issue/crash after delivery?
I guarantee stable firmware. If you find a crash within 30 days of delivery, I'll fix it for free under the Premium package, or at a discounted rate for Basic/Standard.
