SanadOS — Gulf facilities-management and annual maintenance contract (AMC) platform that turns messy multi-site scheduling, asset tracking, and renewal workflows into one coherent system. Built on React, Next.js, Supabase, and PostgreSQL for real-time data across teams and sites, and it's a shipped, actively used product, not a concept build. If you're running or investing in Gulf FM or B2B operations software, this shows he can turn an operationally messy domain into reliable SaaS.
