Systems I built to test an idea or fix a workflow.

One studies how market conditions change strategy behavior. The other turns a manual trading journal into a connected analytics workflow.

Market Regime Detection & Backtesting Platform

Market conditions change how trading strategies behave. I built this platform to classify trend, range, and volatility regimes, then test strategy variants across them.

What I built
The Python workflow engineers time-series features, compares K-Means with an optional Gaussian HMM, and evaluates baseline, regime-aware, and liquidity-filtered strategies with next-bar execution, configurable costs, and Monte Carlo stress tests.
Why it matters
The dashboard keeps regime behavior, risk, and strategy comparisons in one place without presenting a single backtest as a final answer.

Trading Analytics & Workflow Automation Platform

My trading journal required repeated data entry, format checks, daily updates, and rebuilt summaries. I wanted one workflow that kept the data consistent from entry through analysis.

  1. JSON / CSV
  2. Pydantic
  3. Notion
  4. Supabase / PostgreSQL
  5. Analytics API
  6. Dashboard
What I built
The system validates JSON and CSV records with Pydantic, writes structured data to Notion, and syncs paginated records into Supabase and PostgreSQL with duplicate handling and repeatable upserts.
Why it matters
It replaces separate manual steps with a scheduled, traceable pipeline. An analytics API serves the same dashboard structure while keeping private and public data separate.

Experience

From finance into analytics and automation.

My roles at Cox have moved from financial analysis into enterprise reporting, data workflows, and automation.

Cox Communications

Data Analyst II

Build and maintain reporting workflows that move Oracle SQL data into Power BI for finance and business teams. The work includes semantic models, Tableau-to-Power BI migration, validation and reconciliation, Python automation, and translating stakeholder requirements into reporting people can use consistently.

Financial Analyst I

Worked on forecasting, financial modeling, and business analysis with Sales and Finance. That role gave me the business context I now bring to analytics and reporting work.

Financial Data Analyst Co-op

Worked with financial data, reporting processes, data quality, and automation before moving into the analyst roles above.

Amazon

Process Improvement Intern

Used operational analysis and VBA to automate part of a repetitive workflow and improve the process around it.

03 · About

I start with the business question, then work backward to the data and tools.

I came into analytics through finance. At Cox, that has meant working with business and financial data, reporting systems, reconciliation, and automation. That context keeps my technical work tied to how people will use the output.

Outside work, I use personal projects to go deeper on machine learning, data pipelines, workflow automation, and agentic AI. I care most about systems that make complicated work easier to understand and repeat.

Beyond work.

I spend as much time outdoors as I can, especially skiing, hiking, and traveling. I also follow motorsports and have a longstanding interest in Porsche.
