Hello, I'm

Ivan Munandar

Electrical Engineerbuilding the bridge between hardware and software.

I work across electrical engineering, laboratory testing, and IoT — then carry that same precision into the software and dashboards that make those systems usable.

// example — panel voltage & current
type Reading = {
  voltage: number;
  current: number;
};

function readSensor(): Reading {
  const voltage = adc.read(PIN_V) * SCALE;
  const current = adc.read(PIN_I) * SCALE;
  return { voltage, current };
}

publish("lab/panel-01", readSensor());

About

Professional overview

I work across electrical engineering, laboratory testing, and software — building the connective tissue between physical systems and the tools used to monitor and manage them.

Electrical EngineeringThe foundation — circuits, power, and control systems.
Laboratory & TestingApplying that foundation in structured, standards-based testing.
InstrumentationMeasuring and monitoring systems with precision.
IoTConnecting instruments and sensors into networked devices.
SoftwareTurning device data into usable tools and dashboards.
DigitalizationBringing it together into complete technical systems.

Core expertise

Where engineering meets software

Six disciplines that consistently show up together in the systems I build.

Electrical Engineering

Core discipline behind every system I build — from circuit-level design to power and control systems.

Laboratory Testing

Hands-on testing work in accredited lab environments, following structured technical procedures.

SNI / IEC Product Testing

Product compliance testing against SNI and IEC standards, from setup to result documentation.

IoT Development

Connected devices built on ESP32 / ESP8266, linking physical sensors to usable digital data.

Software & Web Development

Web applications and dashboards that turn engineering and lab data into something people can act on.

Instrumentation & Measurement

Sensor selection, calibration awareness, and measurement accuracy across electrical and physical parameters.
