Experience

Data Scientist

DH3 Games
Jan 2023 - Present · 3 years 5 months

A mobile games start-up with two people, but has over 100 million downloads across all apps.
Spearheaded the development of many gaming apps for both iOS and Android devices, gaining over half a million downloads in total. Over 10 games I developed achieved the number one trivia game position in one or more different countries.
Handled key data related tasks, such as integrating software to record user actions using FirebaseAnalytics within the games, storing the data on databases on BigQuery, retrieving the specific data using SQL, then analysing this data with Python on notebooks. Techniques used include A/B testing and multiple linear regression. The goal was to maximise KPIs such as player retention and revenue gain. One A/B test with quiz length was able to improve revenue by an estimated 40%.
