The most amazing...
...code I've done was an algorithm that goes through many units finding which one is blocking the rest of them in order to allow to the user to fix the problem.

Experience
  • System to Monitor Downtime in a Manufacturing Plant (Development)

    The purpose of the project was to create a system that would be constantly monitoring events on databases interacting with the General Electric tool called: Proficy.

    Every time a downtime was registered on the system, our project would scan some tables for information to identify which production unit is blocking the production line.

    To accomplish this, several configuration things needed to be in place. For example, the distance is variable between one production unit and another, for that reason a configurable option needed to be in place to keep this requirement present when the code where looking for downtime gaps. The downtime items were examined until finding the culprit. All the information would be updated accordingly so a panel would be updated in the plant to allow the operator to fix the problem quickly.

  • System to Create and Process (Cut and Recut) Wood Materials (Development)

    This project involved several displays in the GE Proficy workflow and several stored procedures to create items in the database. These items would be processed in different work stations. They would take wood panels, and then create new cuts from them based on certain patterns created in other stations. Some of the displays were also in charge of report waste, defects, and more; each with a specific code that would be read later on by some SSRS reports.

    During the development of this project, a total of 16 different displays were done in order to provide different tools for the people working at the plant. We did this by using a validation process and thus avoided some human errors when they planned the cuts and then produced the panels.
