I will esp32 and arduino firmware developer for iot, sensors, and embedded systems

Struggling with code that won't compile - or a sensor that just won't behave?

I'm Ramim, a Senior IoT & Embedded Systems Engineer. I've built commercial products for factories, fish farms, and smart infrastructure - not hobby projects. I bring that same discipline to every order here.

I don't copy-paste from tutorials. My firmware is clean, non-blocking, and tested for real-world use.

What I work with:

• ESP32, ESP8266, Arduino, STM32
• FreeRTOS, non-blocking state machines
• MQTT, HTTP REST, Modbus RTU/TCP, RS485, RS232, I2C, SPI, UART
• Wi-Fi, BLE, GSM/GPRS, LoRaWAN, ESP-NOW 
• TFT Touchscreen, OLED, LCD
• ThingsBoard, Blynk, Firebase, Node-RED, Grafana
• PCB Design (EasyEDA), schematic review, component selection

Real projects delivered: factory operator efficiency monitor, commercial aquaculture IoT system, LoRaWAN smart water meter.

Every order includes:

• Clean, well-commented C/C++ source code
• Professional wiring connection diagram
• Component selection guidance and hardware advice
• Clear documentation so you understand every line
