  Data and Application Support Assistant

  My office was designing a system that stores all the personnel data and allows users to access them. I participated in data collection and entry. Built a large dataset, cleaned and entered all the data collected into the dataset for the system to better read the data. I constructed the dataset and entered a vast amount of data into it using VBA automation. Significantly improved the efficiency of the team and the accuracy of the data by using VBA. Successfully finished and double-checked the dataset within my work term. I used my Excel knowledge to act as a team leader. Reported to the manager and distributed tasks to my team. Helped my team to understand the dataset and automation to boost efficiency up. Show less
