Built a company profile website with an integrated custom CMS — going beyond a standard marketing site into a lightweight business operations tool. The system lets the internal team manage client records, generate RAB (cost estimation) documents, and issue invoices directly from the same platform, replacing scattered spreadsheets and manual document creation. Directed the full build using AI-assisted development, from information architecture to CMS logic, enabling a non-technical operator to ship a functional internal tool without a dedicated dev team.
