Machine Learning Operations Engineer II (MLOps / ML Platform Engineering)

CliftonLarsonAllen · April 2025 - June 2026

  • Designed and implemented a standardized machine learning platform architecture that unified infrastructure, CI/CD, and deployment patterns, enabling teams to rapidly build and deploy production ML systems.
  • Built and operationalized an end-to-end ML lifecycle system from experimentation to production, including reproducible development environments using container-based workflows and standardized engineering practices across teams.
  • Developed automation and governance for the ML platform, including project scaffolding, CI/CD pipeline orchestration, and environment provisioning using Databricks, Azure DevOps, GitHub Actions, and MLflow to ensure scalability and production readiness.

Machine Learning & MLOps Engineer

Sunthetics · Dec 2023 - Dec 2024

  • Maintained a Bayesian optimization and active learning framework for chemical process optimization, reducing experimental efforts by up to 5x while improving outcome quality.
  • Supported diverse variable types (continuous, categorical, timeseries, chemical) to enable multiobjective optimization across up to 15 objectives with custom constraints.
  • Built scalable, modular, fully typed, tested, and serializable Python packages, ensuring robustness and easy integration with APIs and databases.
  • Applied advanced hyperparameter tuning and surrogate modeling (including CatBoost, XGBoost) for high-dimensional chemical process optimization; integrated Retrieval-Augmented Generation (RAG) systems using LangChain and VectorDB to enhance documentation querying and team productivity.

Data Engineer
