— 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.
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.
