About the Operator

I'm a Python developer and data scientist based in Huffman, Texas. I work at the intersection of software engineering and machine learning — building everything from predictive models and NLP pipelines to the Django and React applications that put them in front of real users.

My toolkit runs deep on the data side: Pandas, Scikit-learn, SQL, and the modeling workflows that go with them — classification, regression, clustering, computer vision, and natural language processing. On the engineering side, I ship production web apps with Django, Flask, and React.

I'm currently available for freelance development and data consulting. If you have data and a problem, I can build the thing that solves it.

LOG_001 // CAPSTONE — CLASSIFICATION

Interconnect Telecom Churn

End-to-end churn prediction for a telecom operator: EDA surfaced that monthly subscribers and fiber-optic users churn hardest (especially in the first four months), then a model was built to flag at-risk customers for targeted retention offers.

Age Verification CNN

Deep learning model for the Good Seed supermarket chain that estimates a customer's age from a photo to support alcohol-law compliance. Fine-tuned a pre-trained ResNet50 on GPU, testing dropout and learning-rate configurations.

Oil Well Site Selection

Profit-optimization study for OilyGiant: regression models predicted reserve volumes across three regions, then bootstrapping with 1,000 samples quantified expected profit, 95% confidence intervals, and downside risk before recommending a region.
