Financial data engineering lab

Turning financial chaos into actionable data architecture

Terabytes of financial data and still no answers? Blockchain transactions, acquiring, Stripe, Shopify, bank statements and service logs all add up to noise. This site is a working lab: browser tools that clean that data, and notes on the pipelines and AI/MCP wiring behind them.
