Professional Experience

Machine Learning Engineer

May 2023 - Aug 2024

CAE USA Inc, Orlando, FL

  • Developed data processing pipelines: Created a repository for processing column-based data and applying machine learning models using Sklearn, XGBoost, and LightGBM. Utilized Kubeflow and Docker to automate hyperparameter tuning with Ray Tune, optimizing model selection and performance.
  • Collaborated on behavior trees for simulation agents: Designed and implemented a collection of 9 core behaviors and multiple subtrees using Rust and XML for autonomous agents within Computer Generated Forces (CGFs) simulations. Contributed to white papers detailing the architecture and documentation for intelligent agents.
  • Implemented MinIO, Trino, and Iceberg on Kubernetes using Helm charts, laying the groundwork for a scalable data analytics layer to process simulation data from CGFs. This work set the stage for future expansion, including UI integration and enhanced data accessibility, as part of a collaborative effort within a 3-person team.
