About this Gig
I develop stable, production-ready ESP32 and ESP8266 firmware using ESP-IDF and Arduino framework.
From BLE Mesh, WiFi Mesh, Zigbee, LoRa, NB-IoT, and 4G-LTE to full cloud-connected IoT systems, I write firmware that runs reliably in real conditions.
What I cover
- WiFi, BLE, and BLE Mesh communication
- Zigbee, LoRa, NB-IoT, and 4G-LTE using SIM modules
- MQTT, HTTPS, and TCP/IP integration
- ESP-IDF and Arduino framework
- OTA firmware updates
- FreeRTOS/Zephyr task management
- Edge AI and TensorFlow Lite on-device inference
- UART, SPI, I2C peripheral interfacing
- HMI display development using LVGL library
- Low power and deep sleep optimization
- Sensor and module integration
What you get
- Clean, well-commented source code
- Tested and working firmware
- Full documentation
- Easy handover
I have built ESP32 solutions for home automation, industrial monitoring, wearables, and asset tracking so I understand exactly what it takes to ship a working product.
Note: Message me before ordering, describe your project and I will confirm what I can deliver.

FAQ
Do you work with both ESP32 and ESP8266?
Yes. I work with both. ESP32 is recommended for new projects but I can work with ESP8266 if you already have hardware.
Which framework do you use — ESP-IDF or Arduino?
Both. I recommend ESP-IDF for production projects and Arduino for simpler or faster builds.
Can you fix my existing ESP32 code that is not working?
Yes. Share your code and describe the issue — debugging is part of my service.
Will my device update wirelessly after deployment?
Yes. OTA update support is included in Standard and Premium packages.
Can you optimize for battery powered ESP32 devices?
Yes. Deep sleep and low power optimization is included in the Premium package.
Do I get full source code?
Yes. You receive complete, commented source code with documentation.
Can you connect ESP32 to AWS IoT or Firebase?
Yes. I have experience connecting ESP32 to AWS IoT, Firebase, and custom MQTT brokers.
