• RHELMSB CVC - Primary developer responsible for migrating existing CVC code (see previous bullet point) onto the RedHat Enterprise Linux platform. Responsibilities included attending regular update meetings with project manager, proactively reporting impacts to estimated time of delivery based on anticipated requirements changes, weekly interactions and cooperation with a testing team,and making design change choices based on needs of customers and project manager.
• Oracle 12c MSB CVC - Similarly to the RHELMSB CVC, I was the primary developer responsible for meeting deadlines and providing deliverables to the testing team and project manager. Responsibilities were comparable to RHELMSB CVC, but the timeline was significantly accelerated, and thusly required teaching new team members the common engine/API and giving them the tools they needed to independently help the team achieve project goals.
• Other responsibilities:
• Mentored interns yearly and provided assistance in completing assigned tasks.
• Served as an ongoing bridge between VA office and Malaysia office in bringing newcomers up to speed on products my team supports.
