Python Charging Station Analysis

Description

Using registered vehicle data, zip codes, and charging station location data, I created a python script that displays all electric vehicle charging stations in NJ relative to the registered EV density per zip code. This project was created in Jupyter Notebook.

Objective

The goal of this project was to create a visualization in Python to display the electric vehicle population density in New Jersey, and compare it to the electric vehicle charging station locations in the state.


Warby Parker SQL Funnels

Warby Parker is a transformative lifestyle brand with a lofty objective: to offer designer eyewear at a revolutionary price while leading the way for socially conscious businesses. Founded in 2010 and named after two characters in an early Jack Kerouac journal, Warby Parker believes in creative thinking, smart design, and doing good in the world — for every pair of eyeglasses and sunglasses sold, a pair is distributed to someone in need.

Objective

In this project, I will use fictional raw data provided by the data scientists at Warby Parker to analyze Warby Parker marketing funnels by calculating conversion rates and other means of data manipulation.

Description

The Superstore is a fictional retail store that sells several products throughout the United States. Tableau provides this data source to every user for free. It is incredibly detailed and allows the users to create all kinds of dashboards. With the data set provided, I created and designed a dashboard that allows management of the Superstore to access all of their KPIs in one view. The unique functionalities of Tableau allow the users to drill down further into their analysis, which in lead can enable them into making some very strategic decisions for the company going further.

Objective

This dashboard was created to break down profit analysis within the Superstore franchise. The capabilities behind this dashboard are endless:

The marketing department is particularly interested in how the churn compares between two segments of users. They provide you with a dataset containing subscription data for users who were acquired through two distinct channels.

Objective

Use the provided subscription data and write a SQL query to compare churn rates accross segments at Codeflix. Discover ways to optimize your query to be used in scale. Follow each step of the instructions provided to reach the end result.


CoolTShirts Marketing Attribution with SQL and Tableau

Description

CoolTShirts sells shirts of all kinds, as long as they are T-shaped and cool. Recently, CTS started a few marketing campaigns to increase website visits and purchases. Using touch attribution, they’d like to map their customers’ journey: from initial visit to purchase. They can use that information to optimize their marketing campaigns.

Objective

With the raw data provided, help CTS learn more about their campaigns. Write SQL queries to provide the answers to each question asked and visualize the solutions in a dashboard accordingly.
