Project History
Data Warehouse for Nielsen Ratings
A data warehouse for Nielsen rating. It includes the ETL process for ingesting the data into a Redshift database and various custom reporting modules written in SQL. I developed a novel way of constructing complex SQL queries.
Productivity Browser Extensions
https://freedom.to/resourcesCreated several browser extensions for Freedom to boost user productivity and block online distractions. These extensions are free to install and were built to showcase the main subscriber product and attract new users. All of them offer some demo features that are included in the main paid product, which consists of a mobile app, desktop app, and Chrome extension.
Automotive Web Solutions
Created a web solution based on ExpressionEngine for Nexus Point targeted at used car dealers in the UK. I integrated the website with the car dealer's internal systems and pulled data from various third-party APIs to make it easier for customers to choose their next car.
YouTube Caching System
A Squid proxy server adapted with Python plugins for caching YouTube videos. We implemented this at Neotel in 2010 in response to a dramatic increase in YouTube traffic, to the point where our customers could not normally watch a video. It was an exciting project because we did reverse engineering on YouTube. After two months of work, we had a solution that saved 35% of the bandwidth we bought from our upstream providers.
The solution ended up being temporary, as Google eventually approved us to host their CDN servers. Still, it was interesting to see that Google's CDN system worked similarly to our design.

Brutus Chrome Extension
A Chrome browser extension that analyzes the HTML content viewed by users and shows relevant actions and ads. It uses NLP processing modules in Python and SQL queries to identify ads relevant to the webpage viewed by the users.
