Case studies
Technical
Systems we build and run ourselves, written up for engineers. Each one covers a problem that was genuinely complex, the constraints that shaped the solution, and the approaches we considered and rejected.
Retrieval-augmented generation
Building a RAG pipeline that can show its work
Answering questions about federal nursing-home regulation, where a confident wrong answer is worse than no answer. Query rewriting, hybrid retrieval, rank fusion, two passes of deduplication, and an answerability check that lets the system decline.
Security & compliance engineering
Provenance and egress control for health data
A hash-chained ledger that records what crossed each trust boundary, who it crossed for, and what came back. Field-level encryption that keeps search working, and offboarding that reaches into six-year-old backup snapshots.
Clinical rules automation
Encoding CMS care-management rules as a testable system
Eight overlapping Medicare care-management programs, each with its own eligibility, time thresholds, and rules about which others it can coexist with. Encoded as cited data rather than buried in conditionals.
Why we publish this
When you hire a studio, you are buying judgment: what gets built, what gets refused, and what happens when a requirement turns out to be wrong. A logo wall does not show you any of that. A detailed account of a hard problem does. Read one of these and you will know fairly quickly whether we think the way you want your engineers to think.
