Contract Software Developer

Responsibilities:

• Worked on the Checkmark product which is used in the manufacturing plants to for Quality Control.
• Rewrote the data access component from ADO.Net to Entity Framework 6.3.
• Fixed production bugs and implemented functional enhancements as they arose.
• Created version 2.0 of the Checkmark product which included a new product infrastructure which capitalized on the Factory software pattern so that new plants could be brought online quickly and their differences abstracted out of the core product code.
