What I'm looking for

I’m looking for a data engineering role where I can build governed, high-fidelity pipelines and dimensional models, automate quality checks, and optimize cost/performance—so teams can move faster with reliable analytics, experimentation, and clear executive insights.

I’m a Data Engineer who deep-dives into complex multi-source datasets (JSON/CSV) to recommend and implement cleansing and quality solutions, turning raw rights-adjacent data into high-value analytical assets with dbt. At CMS Energy, I architected a modern data stack for revenue experimentation, built automated validation to protect data fidelity for product growth and GTM execution, and established data governance frameworks to ensure confidentiality and compliance.

I design scalable dimensional models to connect instrumentation with institutional performance reporting across 80+ cross-functional stakeholders, while using AI Agents and LLMs to accelerate ETL development and proactively resolve schema drift. I also optimize query performance and cost-efficiency in Azure Databricks, automate pipelines with Change Data Capture (CDC), and validate high-volume event attributes for experimentation and predictive modeling.
