Agentic ICF Generator — Transforms Clinical Study Protocol tables into ICF Summary Tables using Skills Cards architecture with scoped MCP tool restrictions. 1–2 days manual → under 5 min.
Vision Agentic RAG — Multimodal retrieval system with DSPy serving a global medical writing team. Retrieval hit-rate@6: 60% → 85% across thousands of documents and images.
Custom Document Parser — Docling-based parser extracting tables, figures, and images from PDFs, RTF, DOCX into structured Markdown; indexed into Weaviate + GCS.
LLM-Judge Evaluation Stack — 4 specialized judges (faithfulness, completeness, patient-safety, alignment) scoring at claim level with source-snippet citations and abstention-aware metrics; MLflow-tracked runs, DVC-versioned golden datasets on Vertex AI pipelines.
Judge Meta-Evaluation — Seeded-error datasets measuring per-judge recall/precision, calibration against medical-writer annotations, cross-model verdict verification (Gemini vs GPT) — grounding raised to 1.00, completeness +7 pts.
Streaming Re-architecture — Re-engineered monolithic application with full streaming: long-running task response time cut from ~2 min to ~4 sec.
Native Word Comment Layer — Backend-driven OOXML pipeline (flat-OPC) embedding LLM reasoning and source citations as native Word comments — every AI output auditable and source-traceable inline.
