Hire Me Because

As an experienced customer service representative I developed keen skills in observation, understanding, and researching unfamiliar viewpoints and situations. Recently I have made the choice to switch to a career in data science where I hope to grow as a professional and be given the opportunity to make an impact in my community.

My Capstone Project: 311 Response Times

Using a CSV acquired from the City of San Antonio’s website, our team aims to create a classification model to predict the level of delay in a call’s response time. We are taking in features such as district code, zip code, department issued the case, category of the case, how the case was reported, and more to achieve this. From this project we want to answer what drives the level of delay and if there is a way to minimize late response times for 3-1-1 calls in our city.
