One category is feature engineering for the
database of contractors and structural engineers in Bay Area, California.
I took the raw data of 7500 registered contractors from
the California State License Boards,
selected the contractors who actually hold worker insurance compensation
and transformed the data into the relationship of Contractors in different cities and
their licensed categories.
The goal is to provide a sortable and searchable database for home owners
to use as a tool to either find
potential contract suppliers and to confirm their license status.
