This letter serves as a reference for Song Zhi Wong who worked as a Process Engineering student for Royal Building Products from September 2014 to August 2015. During his time there, Song was responsible for process engineering support, identifying quality and productivity issues, data collection and analysis, creating reports and procedures. He also participated in continuous improvement projects. The letter states that Song worked well independently and in a team, fulfilled his responsibilities with little oversight, and interacted well with others. The writer, Alice Lai, is happy to provide a reference for Song and discuss his skills, work ethic, and professionalism further.
