I design and build data infrastructure end to end. My core stack is dbt, Azure (Data Factory, Synapse, Databricks), and Python, with strong experience on AWS (SageMaker, Bedrock) as well. Day to day I'm a data engineer at a large national nonprofit where I own everything from ELT pipelines and dbt transformations to production ML models built on CatBoost and XGBoost. I build the pipelines, train the models, monitor the outputs, and fix things when they break. What I can help you build: dbt project setup and data modeling from scratch, migrating legacy SQL into dbt, building and optimizing Azure Data Factory or Synapse pipelines, deploying ML models into production workflows, Python scripting and automation, Power BI dashboards, and Snowflake implementations. I communicate clearly, I scope work honestly, and I deliver on time.

I’m an AI and Machine Learning Engineer working across Machine Learning, Deep Learning, and modern AI systems. I focus on building practical, data-driven solutions using machine learning models, neural networks, and Large Language Models (LLMs). My work covers the full lifecycle of AI solutions - from data preparation and feature engineering to model training, evaluation, and deployment-ready workflows. I have experience working with both structured and unstructured data, applying classical ML as well as deep learning approaches depending on the problem. I’m especially interested in applied AI, where models are used to solve real business and product challenges, not just experimental or academic tasks.
