# everything is open-source in here — github.com/rkriad585
“I'm RK Riad Khan, a passionate and driven software developer, ethical hacker, and cybersecurity enthusiast. I thrive on solving complex problems and building innovative solutions.”
Self-taught, open-source-first builder based in Tanor, Rajshahi, Bangladesh. I design and ship fast, native, privacy-focused tools — from terminal utilities to self-hosted AI interfaces — and publish almost everything I make as open source.
Founding the RK Riad 585 brand across GitHub, SourceForge and PyPI, with a signature design language inspired by Nothing OS — liquid glass, dot-matrix and monochrome discipline.
