The work behind these reviews
The reviews below come from delivered projects, not a highlight reel. Most are Excel and Outlook builds: reporting tools wired into ERPs and accounting systems, CRM panels that live in the inbox, document automation for firms that produce the same contracts every week, and a handful of Teams apps for HR and operations. Clients range from two-person ISVs shipping their first AppSource listing to enterprises rolling an add-in out across thousands of seats. Several of these projects are written up in detail in our portfolio, and the sector-specific work is mapped on our industries pages. Names are shown where clients agreed to be quoted.
