Work Experience
Data Science Contractor
Adarma (for Lloyds Banking Group)
- Designed an analytical framework for deployment to a GCP analytics platform, including code repositories, file structures, standard procedures, and analytical tools.
- Created a graph (network) dataset for application vulnerability analysis comprising more than 100,000 concepts and double that of relationships between them, which were used to holistically assess security across the bank's digital estate.
- Introduced agile methodologies to a team of security analysts.
Development Team Leader
TVSquared
- Led the development of a television advertisement detection system called TVsquared.tv, which involved coordinating a team of developers, DevOps, and designers, personally implementing a detection algorithm in the back end, and liaising with managers.
- Designed and built the back end for TVSquared's Predict, which uses historical client advertising performance data to recommend changes in future advertising spending.
- Refactored multiple back-end processes to reduce infrastructure costs by moving processing out of AWS RDS database instances in favor of running parallel processes on cheap spot-instances using Spark.
Database Administrator | Development Team Leader
Peoples Postcode Lottery
- Served as the technical lead for the Postcode Finder project at the People's Postcode Lottery, which visualizes all historical winning entries on an interactive map.
- Performed probability analysis of lottery player:postcode ratios to inform the finance and marketing departments on likely win amounts and risk exposure.
- Led two projects integrating external data sources into a PostgreSQL data warehouse: the history of player activity from an outsourced e-gaming website with more than 80,000 users and customer profiling data with more than 20 million records.
Experience
Predict from TVSquared
http://www.tvsquared.comAs well as leading the project, I designed the new back-end prediction algorithm, which uses Spark parallel processing to evaluate all possible combinations of up to five dimensions of categorical descriptors of advertising spot data. This original method resulted in a back end that would always produce buying recommendations, providing a few basic data requirements were met.
