six titles, one recurring job

The report did not exist, so I built it.

Six roles in healthcare operations, and underneath every title the same job kept appearing: the reporting the place ran on had not been built yet. Everything linked here is deployed and reachable, and every figure names where it came from.

Five facilities across twelve months. Rendered from the same figures the case study reads, not screenshotted. Collected runs at 56.9 percent of billed once the contractual write-down comes out, and a denial traces back to payer, provider, and CPT.

carbon

A project, a to-do list, and a goal held side by side on one database I own. Every table is a real PostgreSQL table with typed columns, so a filter runs inside the database rather than in a browser sifting rows it already downloaded.

carbon.huy.gg

codemap

A code index that answers questions about a repository without reading it: where a function lives, what calls it, and what breaks if it changes. No language model in the loop.

huy.gg/codemap

Claude Code analytics

An analytics console over my own session history: what each session cost, which model is reliable and at what price, when the output happens (across weekday and hour), and which skills it is attributable to.

Facial emotion recognition

Four model iterations from a baseline neural network through refined convolutional architectures, reaching 91 percent accuracy across four emotion categories.
