8+ years delivering data systems across regulated environments — production pipelines, cloud-native architecture, and compliance-grade testing in healthcare and financial services. Current focus: revenue cycle management, FHIR R4 claims analytics, and AI enrichment layers with structured validation governance.
P2 classifies denials retrospectively → P3 adds AI governance → P4 prevents denials in real time
| Project | Domain | Status | |
|---|---|---|---|
| P2 | Denied: Healthcare Claims Intelligence Pipeline | RCM · RWE | ✅ Live |
| P3 | Trust but Verify: Clinical AI Governance Engine | AI Governance | ✅ Live |
| P4 | Cleared: Real-Time Prior Authorization Prevention Pipeline | Streaming · Denial Prevention | 📋 Planned |
Classifies 257K denied claims by root cause — systematic denials vs. documentation failures — where the remediation path differs fundamentally for each.
| Stack | Synthea FHIR R4 · Python · Snowflake (RAW → staging → mart) · dbt · Dagster |
| Scale | 495K total claims · 51.9% denial rate · $1.2M+ recoverable · 12 dbt models · 83 tests |
| RWE | T2D/CKD cohort · 104 patients · 54.8% metformin utilization |
Dual-validation AI governance — LLM enrichment cross-validated by a deterministic rules engine. Every record routes to Gold (trusted) or Review (explainable reason). No black-box outputs.
| Stack | FHIR R4 · Python · Snowflake · dbt · Dagster · LLM API · Pydantic |
| Scale | 226 patients · 25,958 clinical records · 6 enrichment categories · 6 rules engine domains |
| Design | LLM-as-Judge blind audit · prompt caching · confidence threshold routing |
