Projects

AKREtrack

TypeScript Cloudflare Workers D1 R2 Astro

Fully automated ETF holdings tracker. A scheduled Worker fetches a daily CSV, writes structured data to D1, stores the raw file in R2, runs a diff engine to detect buy/sell/trim events, and triggers a Cloudflare Pages rebuild via deploy hook — all in a single execution with hash-based deduplication to handle stale upstream responses.

ETF Activity

Astro Cloudflare Pages Cloudflare Workers

Active development of a broader ETF tracking application, expanding on the data pipeline capabilities built in AKREtrack.
