Maria Ching grew up in a small town called Daet, then moved to Manila when she went to college. She took up Computer Studies at De La Salle University and graduated in 2005. She started using open source tools from her first job after graduating and from then on, got interested in everything open source. When she came to work for Exist, she got assigned in a project doing a lot of development work in open source projects, specifically Maven, Continuum, and Archiva. Back then, Continuum and Archiva (formerly named Maven Repository Manager) were still sub-projects of Maven. Eventually, she became a committer, then a PMC member of Maven. In 2008, Continuum and Archiva became top-level projects at the ASF and Deng was elected as PMC Chair of Archiva. She is still currently serving as PMC Chair of the project and as PMC members of Continuum and Maven.
