- Built a streaming statistical-analysis pipeline (Welford's algorithm + reservoir sampling) over 10M+ observation datasets, with complexity-score routing between sync and async Cloud Run jobs to keep cost down and previews instant.
- Shipped a production OAuth2/OIDC identity provider from scratch — PKCE auth-code flow, RS256-signed ID tokens, SHA-256 hashed token storage with MongoDB TTL expiry — powering 15 endpoints and 6 scopes, plus a JavaScript SDK for one-import login.
- Deployed a cloud-optimized raster tile server on Cloud Run serving 268K+ datasets in COG / STAC / Zarr formats, with tuned GDAL caching (HTTP/2 multiplexing, 200MB curl cache) and 4 custom scientific colormaps.
