This includes backend code to control the lasers and communicate with hardware in the system, and frontend code to provide controls to the user and visualize data. • Developed, from project conception to customer shipment, a new Windows desktop application written in C# with a WPF user interface (MVVM pattern) for controlling a vacuum ultraviolet (VUV) laser source. • Improved and maintained existing applications written in LabVIEW (interfaced with C#) for controlling an ultrafast Ti:Sapphire laser amplifier system and a high harmonic generation (HHG) laser system. • Interfaced software with many different hardware devices over various protocols (serial, TCP/IP, I2C, Modbus, analog). • Wrote device control code for ADCs/DACs, cameras (USB and GigE), delay/pulse generators, environmental sensors, general purpose I/O devices, laser diode drivers, motors, picoammeters, pressure controllers, spectrometers, and temperature controllers. • Added an API to a laser system so customers could control the system with commands over TCP/IP or through a DLL. • Started developing the framework for a control application written in Python with a Qt user interface (QML). • Worked closely with laser, electrical, and mechanical engineers to develop and improve the laser systems. • Kept the software backwards compatible as new versions of the laser systems were developed. • Often had to accommodate specialized, one-off versions of the laser systems in the existing software. • Used C# wherever possible in the LabVIEW applications to decrease development time. • Provided software support for customers of our laser systems. • Interviewed potential candidates for various positions at the company. • Used Jira to track tasks, bugs, and progress. • Managed Jira for the company. • Used Git for version control.
