Create and integrate Outlook add-in Leon is phenomenal - the amount of technical expertise Leon brought to the table blew us away. His contributions to our very complex project have improved our bottom line and the product itself. As a business owner, I cannot recommend Leon enough. Truly winning the Upwork lottery when you work with Leon.
