— Introduction
I build clean and modern web interfaces, and explore IoT and radio technology through hands-on projects and experiments.
Hi, I’m Rayhan (YC5NCM) an amateur radio with a deep curiosity for web development, IoT, and satellite communication. I love exploring how software, hardware, and communication systems intersect to create real and meaningful solutions.
With a background in Information Systems, I combine practical engineering, hands-on experimentation, and clean interface design. My work spans from frontend development and UI/UX design to building IoT prototypes, satellite communication setups, signal monitoring tools, and custom electronics for amateur radio operations.
I enjoy turning ideas into simple, and efficient projects. My goal is to create technology that is not only functional but enjoyable, and to continue sharing knowledge through open-source projects, experiments, and community activities.
Tools and technologies I use to build practical and innovative projects.
Best collection of projects I've built.
Personal motorcycle dashboard with a custom SVG speedometer, digital odometer, fuel efficiency tracker, and maintenance status — featuring a password-protected private mode backed by Supabase.

A transparent donation tracking system for ORARI's MUSDA IX event, pulling live data from Google Sheets with real-time search and visual status indicators.

An Arduino-based tool for FT-818 that reads frequency, mode, and performs LNB calibration for real-time QO-100 transponder monitoring.
A lightweight APRS tracking and gateway system using IoT hardware for efficient amateur radio position reporting.
A smart weather station that collects temperature, humidity, and pressure data, then transmits it via APRS or internet for real-time environmental monitoring.
National video editing training & certification based on Indonesia’s SKKNI standard.
A Hackathon event for Developers, Designers and PMs to collaborate and build a project in one night.
Young Amateur Radio Operators camp to learn about radio communications technology innovations.
Kwartir Management Capacity Building for Scout Leaders in Indragiri Hilir.
Training on water rescue techniques and skills for emergency situations.
