At ACT Financial Systems, I worked on Quasar, an investment management system written in Mumps, running on Digital VMS and Sequent (Unix) systems.
As part of a small team of three, I developed the Quasar PEP (Personal Equity Plan) module, an investment instrument in the UK similar to a modern ISA. We managed the project through its full life cycle, including screen design, module coding, unit and integration testing, and writing user manuals.
In addition to development, I provided ongoing support for this module and many others at ACT.
