COURSE PROJECT:
Software System Engineering Project (VB/Visio/PowerPoint/Word)
Our team of six software engineers designed and implemented a Home Heating System according to an imaginary client’s requirements. We went through the concept of operations, requirements analysis, design and test planning phases of the software development lifecycle. My responsibilities include the design phase and test phase, and I cooperated with teammates on the requirement phase. All documents we produced followed IEEE standards.
Database Design & Implementation (Oracle)
Teamed up with two other students to design and implement a distributed business database system for a fictional supermarket chain using Oracle 8i.
