Hi, I'm Abdur Rehman 👋

ERP Developer · AI & Automation Engineer · Android Developer · Pakistan · available worldwide

I build the software businesses run on every day. My main project is a production ERP that 7 departments of a textile mill use live, plus an AI assistant inside it and a camera system that stops a machine when a person enters a danger zone.
