Experience
Online Reinforcement-learning Platform
The company's revenue was in the millions and this platform generated measurable uplifts (double figures range) in the top line, bottom line, and conversions. My platform included the ability for organization members to configure and deploy new optimization algorithms on subsections of traffic. I also provided a fully customized dashboard app for the hourly tracking of metrics, with the ability to deep-dive into the algorithm behaviors and outputs for explainability, debugging, and further algorithm development.
