As a

variety of clients in a number of different industries: GAMING PAYMENTS Technical
architect and hands-on developer for large payment processor who decided to
enter the gaming payments market and offer both check and card payment
services to brick and mortar and iGaming operators. This was a long-term project and resulted

the casino industry. Participated
as a member of their Innovation Lab, producing several Bluetooth mobile
prototypes that eventually became their cash-less gaming product. BANKING AND FINANCE Provided
communications integration and programming services to a large San Francisco

was successfully delivered on-time despite the complexity of the technical
solution. PHARMACEUTICAL DISTRIBUTION Provided

a large pharmaceutical distributor that was modernizing their ordering system
and creating real-time interfaces for their customers. Modified the order interface design and
back-end systems to accommodate rapidly changing requirements as the company
went through mergers, warehouse consolidations, outsourcing, and eventual
migration to an SAP-based fulfillment system. MANUFACTURING Worked
with several prominent US-based manufacturers to design and implement updated
host interfaces for sales and ordering systems as their back-end systems were
converted from custom-written to packaged software solutions. In all cases, the improved systems
increased customer satisfaction and allowed real-time, two-way exchanging of
order and inventory data. |
