I pulled data from the database and formatted that data in ways that the machines accepted. I was also responsible for the reports that went along with the checks and labels

  • Another project I worked on was to generate letters and files for healthcare companies. I created files that were sent to Quadient Inspire. From there, I created the letter that was printed on large room size printers. Part of that letter were 2D barcodes.
