Sr. Systems Developer

  • Reported directly to Regina Martin Global Applications Technical Lead eCommerce and Retail Integrations
  • Served as lead developer/architect on a variety of integrations and web applications leading a team of developers and DBA s providing solutions integrating into 3rd party application portfolio as well as into the core ERP system provided by Microsoft Dynamics AX 2012 CU7/R3.
  • Architected and implemented an Asp.Net MVC 5 n-tier solution which replaced a legacy payroll system for our Sealy plant software. This software supported approx. 600 factory floor workers with their day to day time tracking needs as they performed various functions on the assembly line. Throughout their shift they would accumulate a book of chits barcodes which would then need to be scanned at the end of the day at terminals located throughout the plant floor. Various other codes were keyed in as well the complex calculations of which ultimately generated various reports and worksheets that were fed into workflows to ensure specific payroll departments within the plants received correct payroll info. Scanning of chits and the subsequent response times presented an interesting challenge due to the near real-time requirements needed by the plant workers. Response time was engineered to be < .10/second due to aggressive caching algorithms and SQL Server callbacks/triggers. The system processed approx.10 000 transactions/day and was integrated into other modules via MSMQ event triggers to facilitate the workflow processing. Note I have a detailed architectural document for this application available upon request . I lead a team of 3 developers a DBA and a dedicated BA. SQL Server 2012 was used as the persistence layer with a mixture of LINQ and T-SQL stored procedures for data persistence and IIS 8.5 on Windows 2012 was used as the application host.
  • Architected an over-arching Payment Gateway system to facilitate eCommerce payment solutions for both web based eCommerce purchases using ShopVisible and DemandWare as the frontend web solutions as well as POS payments processed in stores. Payment processing was offloaded to CyberSource Tempus and TeleCheck as our 3rd party vendors. Payments could be processed at one of three endpoints
  • o On the web via our eCommerce solutions.
  • o From a POS terminal inside store locations.
  • o Via Dynamics AX 2012 for our call center.
  • All transaction ultimately were funneled via various SDK s and custom services into one centralized Payment Gateway which was implemented as a WCF service endpoint sitting just inside the DMZ. The service had another outward facing endpoint on the outside of the DMZ which facilitated transaction processing with the 3rd party payment providers. A series of reports were developed using SSRS for transaction tracking order history and various other bookkeeping functionality. Custom AIF services were also developed within Dynamics AX allowing integration into the core AX workflows for our business users.
  • Served as lead developer for our core integrations product developed in house known as Plug n Play. This software was a custom WCF/MSMQ service acting as a fa ade into various AX AIF services and served as a conduit for passing around various XML messages with complex transformations as these messages flowed from system to system. What Payment Gateway was for payment information Plug n Play was to order management and tracking from our various 3rd party eCommerce solutions into the AX ERP system.
