I will develop iot firmware, cloud and mobile apps for esp32, stm32 and arduino

Hi, I'm Kofi, an Electronics Developer focused on IoT, embedded hardware, firmware and connected applications. I help turn an idea, prototype or existing device into a reliable product, from concept through prototype, integration, testing and deployment.

My Basic package covers IoT device setup, firmware and hardware integration using ESP32, STM32, nRF52, Arduino or Raspberry Pi.

Standard adds WiFi, BLE, LoRa or MQTT connectivity, cloud/API integration and a monitoring dashboard.

Premium covers hardware integration, embedded firmware, cloud, database, APIs and a mobile/web interface.

I can build Flutter apps for iOS and Android with WiFi, BLE, NFC and MQTT, plus Firebase, AWS IoT, Azure IoT, REST APIs, WebSockets and secure authentication.

Also, I handle

• PCB design
• Densors
• Displays
• Motors
• Gateways
• OTA updates and device testing.

Deliverables will include

• Source code
• Schematics
• PCB files
• BOM
• Documentation and deployment support.

I'm also happy to sign an NDA when required. Send sketches, existing files, specifications or simply explain what you want to build.

I'll review the requirements. Have a project in mind? Send me a message and lets build it.
