01 / RESEARCH
Python analysis
Versioned analytical workflows support repeatable historical tests, controlled comparisons and review of assumptions.
Python · reproducibility · reviewTECHNOLOGY / STACK
Make the work reproducible.
Keep the boundaries clear.
A public view of the tools and engineering principles behind the portfolio. It describes the approach without exposing private models or production architecture.
FOUR CONNECTED LAYERS
From research notebook
to a reviewable interface.
Each layer has a distinct job. Passing one layer does not imply that another has been validated.
02 / DATA
Provenance first
Timestamp and information-availability checks keep a result tied to the data that could have been known at the time.
time ordering · lineage · validation03 / WEB
Typed web interfaces
TypeScript and Next.js support the public portfolio and clear boundaries around authenticated tools and services.

Operational separation
Execution, monitoring and risk controls are engineering concerns distinct from a historical research verdict.
service boundaries · observability · riskEngineering boundary: A reproducible backtest is a research artifact. Forward operation, risk controls and deployment each need their own review.
