    “Typical Mark. … That guy is amazing.” —Joel Brazle, Backcountry

    Bcrypt encryption support for Interchange: In order to meet increasing compliance demands for PCI-DSS, expanded the core encryption options for password management to include bcrypt. Converted a number of End Point Dev clients from their existing password management for user and administrative accounts over to bcrypt.

    Tax Jar integration for Interchange: In response to the Wayfair court decision, many ecommerce implementations face compliance challenges. To provide an option for 3rd-party tax services, constructed a connector to Tax Jar that allows a seamless interface to Interchange’s existing sales tax algorithms. The framework allows for interested developers to produce their own support modules for other 3rd-party tax providers through a well-defined API.

    Affirm payments integration: Created new Interchange support to offer instant credit for qualified buyers through Affirm.
