Ahmad Harb

I build and scale multi-tenant SaaS platforms and backend systems for 1M+ users, architected for resource efficiency, performance, and uptime. This page is styled like the dashboards I build: containers below are real projects, the log tail below that is a real career, and the terminal at the bottom takes real commands.

All-in-one multi-tenant POS operating system for retail and e-commerce: digital storefronts, local register hardware and stock control on a single screen. Supersedes both mashroo3.net and the internal Pocket CRM/POS suite. Talks to USB scales and checkout peripherals over the Web Serial API, with a Stripe Connect + Terminal + Issuing pipeline routing daily profits to B2B supplier cards.
