01 / A LITTLE ABOUT ME
An engineer’s mindset.
A founder’s drive.
I’m Md Ariful Islam, also known as Khan Arif (খান আরিফ). I started my software engineering journey in 2020, alongside freelancing on Fiverr and the early, private beginnings of CodeStation AI.
Today, I serve as CTO at Gomax Automation and lead CodeStation AI. In 2026, I launched CodeStation AI LLC, registered in the USA. CodeStation AI is also registered in Bangladesh. My work brings together software development, GPS tracking platforms, and technical leadership.
I build mobile apps, web platforms and backend systems, connecting business needs with practical engineering.
