IoT Prototyping & Embedded Development

By Marfin Pro · Developer, Engineer & Designer, based in Indonesia

Sensor-based prototypes for room monitoring and connected devices. Firmware, data flow, and dashboard setup can be scoped remotely around the hardware you have available.

I hold a degree in Electrical Engineering. Past prototypes include an ESP8266 room monitor that streams temperature and humidity to a Blynk dashboard, and a PIC16F84 line follower robot programmed in assembly and simulated in Proteus.

How a remote project works

  1. Step 1

    Share a brief

    Send what you want to build, who will use it, and any existing website, design files, or hardware. Include your time zone, target launch date, and budget range.

  2. Step 2

    Agree on scope

    We agree on deliverables, review points, and a schedule before work begins.

  3. Step 3

    Build and review

    Work is shared at each review point so you can give feedback while changes are still cheap.

  4. Step 4

    Handover

    You receive the deliverables, source files, and notes listed in the scope.

Frequently asked questions

Can an IoT project be done remotely?
Yes. Firmware, data flow, and dashboards are scoped around the hardware you have. Wiring notes and setup instructions let you assemble and test the device on your side.
Which boards and platforms have you used?
ESP8266 (Wemos D1) boards with the Arduino IDE, the PIC16F84 in assembly, DHT sensors, and Blynk Cloud dashboards.
Do you build production hardware?
The service covers prototypes and proofs of concept. Production electronics, certification, and manufacturing are outside its scope.
