No matter the project, if my studies allow me to have available time, I can complete your data analysis, database manipulation, and other data related projects for you or your business efficiently and with close attention to detail. I also have experience in the following areas: SQL, MongoDB, Microsoft Access, and javascript libraries such as charts.js or D3.js.
