A public Python library I built. Standardize invoice dates, reporting periods and calendar expressions—then see the result feed a live cash-forecast example.
I'm C.J. A finance strategist who codes, builds data platforms, trains models, and obsessively removes the distance between information and action.
Python libraries I built and published for anyone to use—from cleaning financial inputs to automating reporting and analyzing market data. Choose a library to try it live, explore the code, or install it.

Helps automated finance reports and data workflows connect to Microsoft services with fewer repeated sign-ins. Built on MSAL, with encrypted token caching and OS credential storage to help keep client secrets out of scripts.
A Python library for financial data and analysis. This live demo showcases its technical-analysis module with nine indicators, configurable windows and inspectable calculations.
Patterns I've applied in enterprise finance and analytics environments, where accuracy, resilience and stakeholder trust matter as much as clever algorithms.
Normalize fragmented ERP, CRM, billing and operating data into governed models that let decision-makers ask better questions without arguing over definitions.
Connect time-series and machine-learning models to business drivers. Validate accuracy, explain assumptions, monitor drift, then deliver the outputs where people make decisions.
Data lineage, reconciliations, repeatable testing and exception monitoring turn automated analytics into defensible management reporting.
Enterprise systems are described at a high level. Visuals are original illustrations; no private datasets, architecture diagrams or source code are disclosed.
Curious where to go next? A small browser-only command console will help you navigate the portfolio. Try help, projects, stack or finance.
Strategic finance problem, data problem, or a little of both—those are my favorite conversations.
