Confidential, El Dorado Hills, CA

Software Development Manager, Senior Software Developer


  • My roles and responsibilities at Confidential revolved around four primary Confidential responsibilities
  • Confidential Customer Portal - a Java EJB 2.0 web app using OJB as the ORM and WebLogic as the application server; migrated to Spring MVC framework.
  • International Factory System (InFact) - the factory production application; a monolithic desktop Java Swing application using OJB.
  • Offshore software development manager/developer position in Bangkok, Thailand; hired and managed a team of 15 Thai offshore software developers and Q.A.'s
  • Support for Factory web applications:
  • 3rd party Pre-Sort Dashboard Web
  • Full-Service Web
  • ImageLogger Web
  • DataLogger/FactoryLogger Web
  • Problem Insert Reporting Web
  • International Factory On-Call Web
  • Cubic Pricing Web
  • Job Tracking Web
  • My starting position with Confidential was in a Senior Software Engineer role responsible for Direct Access, a PowerBuilder application used by Confidential customers for information about their factory jobs
  • Using Direct Access as the base, along with another developer, created Direct Access(DA) Web, a web site portal that replaced Direct Access to provide Confidential customers the means to release jobs, query jobs, and print reports along with other functionality; this web app progressed over time into a J2EE Portal using EJB technology and later advances into Spring framework
  • As DA Web matured, circa 2002, worked on the team to refactor it from PowerBuilder using Jaguar to Java EJB 2.0; The company renamed the application the Factory Portal; Continued work on this until transferred to International Factory(InFact) team to implement a factory in Argentina
  • Worked on the Argentina project where we customized and installed the Confidential U.S. factory system in Buenos Aires, Argentina; responsible for the Factory Control System, written in PowerBuilder, and the DA Web (crosscut of functions appropriate for this factory) portal
  • Continuing in my role as lead developer for the InFact team, Confidential acquired a print factory in Bristol, UK. Much like the Argentina project, I was responsible for the Factory Control System, written in PowerBuilder, and the DA Web (crosscut of functions appropriate for this factory) portal
  • Recognizing that our InFact system was comprised of many disparate software systems written in different languages (C++, Visual Basic, PowerBuilder, et al.), developed the Java-based International Factory System (InFact), a production system written in Java using Swing GUI framework for the front end over an Oracle database
  • Promoted to Software Development Manager and assigned the role of building an offshore project support team of software developers in Bangkok, Thailand. Hired, trained, and managed a team of 12 - 15 Thai native Java and C/C++ software developers and Q.A.'s.
  • Returned to the U.S. and continued coding and managing the Thai team responsible for UK InFact and more than 20 significant new Confidential projects. Most of these projects were J2EE web sites that provided revenue for Confidential
