I will program arduino and esp32 firmware for your iot project

Looking for reliable, clean firmware for your Arduino- or ESP32-based project?

I'm an embedded firmware developer with a background in Instrumentation & Automation Engineering, meaning I understand sensor behavior, noise, calibration, and control logic, not just how to blink an LED.

Services Offered:

• Arduino & ESP32 firmware development
• Sensor integration & calibration (temperature, pressure, IMU, ultrasonic, IR, GPS, etc.)
• Serial communication: I2C, SPI, UART
• Wireless connectivity: WiFi, Bluetooth/BLE
• IoT data handling: MQTT, HTTP, Firebase, ThingSpeak, Blynk
• Control logic: PID, state machines, automation sequences
• Debugging & optimizing existing sketches/firmware
• Code documentation & wiring diagrams

Tools I Use: Arduino IDE, PlatformIO, Embedded C/C++, RTOS

File Formats Delivered: .ino / .cpp source files, wiring diagram, documentation (PDF)

How It Works:

1. Share your project requirements and hardware list
2. I confirm feasibility and provide a fixed quote
3. Development with progress updates
4. Testing & delivery with revision support

Have a rough idea and not sure what hardware you need? Message me before ordering happy to advise on components.
