- Co-developer of new Point of Sale (POS) systems for Big Lots Stores Inc., Ascena Retail Group and PetCo Inc. built on JumpMind's OpenPOS open-source based POS system, to which I am also a major contributor. The system allows a retailer to leverage their legacy Oracle Point of Service (OrPOS) codebase, while giving them the capabilities to add new functionality for their stores using modern platforms and responsive web technologies. The product is currently deployed in over 1,000 of Ascena's brand retail stores and is currently in the process of rolling out to the Big Lots Stores retail chain. For Ascena, I also served as technical lead of the development to add EMV (chip-based card) support to Ascena's point of sale systems. The EMV upgrade was successfully deployed to thousands of Ascena's brand retail stores where my code and integration work is processing hundreds of thousands of card authorizations for Ascena's retail customers on both mobile (iPads) and fixed registers. For JumpMind's OpenPOS, one of my focus areas has been on design and implementation of components that handle payment authorization. I have worked on a wide variety of new development, integrations, and DevOps across the full application stack for deployment targeted to various device form factors from the iPod Touch to Windows PCs. Technologies: Java 8, Angular, Spring Boot, Javascript, Cordova, iOS, Gradle, Atlassian stack.
