hakupao/README.md
Bojiang Zhang, Clinical Data Engineer (Oncology). A clinical data pipeline built from my repos: raw EDC exports, then MedAudit (audit), DataForge (prep), SDTM Mapping System (map), SDTM Spec Forge (spec), ending in SDTM datasets and an M5 package, all on top of the SDTM Pedia knowledge layer.

I turn raw oncology study data into CDISC SDTM datasets, and build the tooling around that work.

bojiang.org · Open to remote roles, and roles in Japan or Australia

🧬 The pipeline, repo by repo

Stage Project What it does
Audit MedAudit Diff Watcher Watches versioned data drops; row- and field-level CSV diffs in an SQLite audit trail
Prep DataForge Studio Windows toolbox for conversion, cleaning and masking, for analysts who don't write Python
Map SDTM Mapping System One Excel workbook drives a 7-step pipeline to SDTM datasets and an M5 package
Spec SDTM Spec Forge Rust CLI that writes dataset-spec workbooks against SDTMIG v3.4 and CDISC terminology
Knowledge SDTM Pedia 293 Markdown files · 63 domains · 37,939 CDISC terms, searchable by people and LLMs

🔨 Now building

  • A configuration-driven visual ETL platform for clinical data · Rust engine, Tauri + React desktop UI in design
  • A web workspace for authoring and versioning SDTM transformation configs · React · FastAPI · SQLite
