Healthcare AI · Agentic Systems · LLM Infrastructure

Currently building production AI at Elyx — agentic clinical workflows, OCR-to-FHIR pipelines, and evaluation harnesses on AWS and GCP.

Why this work

Most AI systems fail not because the models are weak, but because the surrounding infrastructure isn't ready for production.

I build trustworthy AI systems for high-stakes domains — healthcare, scientific discovery, anywhere accuracy and traceability matter as much as capability. My work spans agents, retrieval, OCR-to-FHIR pipelines, healthcare interoperability, LLM evaluation, and the cloud infra that ships them. The goal is simple: help clinicians spend less time searching for information and more time making informed decisions.

Selected work

A handful of things I've shipped.

Clinical evidence-appraisal copilot (Elyx, 2025)

Multi-agent system that synthesizes findings from top medical literature, clinical guidelines, and trusted sources into citation-backed answers for care teams.

OCR-to-FHIR pipelines (Elyx, 2025)

Convert scanned reports and unstructured clinical documents into structured, queryable healthcare data so PDFs become first-class citizens in EMR workflows.

AstroRAG (Harvard IACS, 2024)

Context-aware retrieval over the NASA ADS astronomy corpus. Mistral 7B fine-tuned for abstract optimization and title generation; end-to-end LLMOps pipeline.
