Same Data, Different Runtime: Elixir and Python for Data Science

A fixture-backed comparison that holds the BLS source, transformations, K-means settings, and acceptance criteria constant, then asks what Elixir and Python make easier to inspect and trust.

Reader outcome: Reader can design a cross-stack experiment that tests output agreement without turning a small analytical workload into a misleading language benchmark.

Two Private Sports Labs, One Evidence Contract

Why I kept Sunday Lab and NBA Lab private, unified their forecasting vocabulary, and published the boundary instead of pretending two local prototypes were live products.

Reader outcome: Reader can separate facts, market observations, forecasts, decisions, and evaluations in a practice system without mistaking a private prototype for a live product or measured outcome.

The Rewrite Sprint That Made My Archive Earn Its Labels

A retrospective on the rewrite sprint that started when a 40-post archive audit found essay and case_study labels attached to note-depth drafts.

Reader outcome: Reader can audit a technical-writing archive by separating tier labels from body evidence, then choose which posts to expand, retag, or hold.

Dataform + BigQuery Governance Release Patterns

A Dataform and BigQuery case study for turning data contracts, release lanes, validation gates, rollback behavior, and cost checks into one governed promotion path.

Reader outcome: Reader can inspect a sanitized release pattern that makes schema, freshness, cost, and downstream-impact checks part of promotion rather than after-the-fact review.

Compliant GCP Platform Playbook for Analytics and ML

A sanitized GCP platform case study where compliance, analytics delivery, and ML feature access had to be designed as one release path instead of three disconnected workstreams.

Reader outcome: Reader can inspect a sanitized GCP pattern for governed dataset onboarding, auditability, cost visibility, and promotion rules across analytics and ML use cases.
