About

With 12 years of experience, Brent is a seasoned professional with a strong background in software engineering, data science, and data engineering. Proficient in a wide array of technologies including AWS services, build and integration systems, databases, Natural Language Processing tools, Python technologies, and data visualization tools. Experienced in the full product lifecycle from design to deployment and maintenance.

Acomplishments

At Edmodo, I led a project focused on improving question reuse functionality for teachers. Utilizing PyBossa, I meticulously labeled and analyzed 10,000 questions, creating a test dataset of 2,000. Leveraging advanced natural language processing techniques and retraining a BERT language model, we achieved an outstanding F1 score of approximately 0.87. This success was met with enthusiasm from both management and team members. Technologies used include PyBossa, BERT language model, and natural language processing techniques.

At Clari, I led the transition from an overloaded Cassandra database to a sharded set of Postgres databases, significantly improving update times for customers from every 12 hours to every 5 minutes. Despite challenges with shifting priorities and team dynamics, I ensured project completion through meticulous analysis, rigorous testing, and seamless migration strategies. Technologies involved included Cassandra, Postgres, and custom-built software for mathematical modeling and load testing.
