Data Scientist & Analytics Leader with 7 years building systems that power business operations and strategic decision-making.

I've led development of automated reporting systems, advanced ML models, and managed end-to-end data pipelines. At Summersalt, I grew to managing the full data stack (Stitch, dbt, GCP, LookML, Looker, custom web apps) and owned the metrics layer powering their BI ecosystem. I've built LSTM forecasting models predicting net revenue with >96% accuracy, web scraping pipelines processing thousands of job descriptions, and production LLM integrations. I'm always focused on making data systems clear, connected, and built for impact.

This is my personal GitHub; it's mostly portfolio pieces showcasing professional work, plus some random stuff like my NeoVim config (feel free to ignore that).

🧠 Data Philosophy - How I think about creating value with data in organizations
If you want to understand my strategic approach to data work, start here.

🔍 Job Posting Analyzer - Production-grade Python framework for web scraping & NLP analysis
My best code: extensible class architecture, 7 scraper patterns, multi-stage quality assessment with OpenAI & LanguageTool APIs.

📊 Multi-Touch Attribution Synthesizer - Interactive Streamlit app for attribution modeling
Statistical simulation (Poisson, Markov chains) + visualization. Could use a refactor, but it demonstrates my marketing analytics & dashboard skills.

• ML & Forecasting: revenue forecasting, Media Mix Modeling, customer segmentation (>1M customers)
• Analytics Engineering: dbt pipelines, semantic layers, self-service BI platforms
• NLP & Automation: RAG prototypes, embedding-based skill extraction, automated reporting systems
• Leadership: Cross-functional initiatives, stakeholder management, mentoring analysts

Languages: Python, R, SQL, LookML
Data Infrastructure: dbt, GCP, BigQuery, MySQL, Docker, Stitch, Git/GitHub
ML/Analytics: LSTM, MMM, RAG, ARIMA, scikit-learn, keras, experimental design
Visualization: Looker, Streamlit, Tableau, Plotly, Superset, Metabase

I'm always open to conversations about data work, interesting problems, or potential collaboration.
