20+ years building high-concurrency backend systems across banking, e-commerce, recommendation systems, and AI infrastructure.
- Currently at InfiniFlow — leading RAGFlow's Python→Go platform migration: 200+ merged PRs covering the document REST API layer, task executor, ingestion pipeline (PDF/DOCX/PPT/email parsers, chunker, tokenizer, embedding), knowledge-graph retrieval, and the DeepDoc inference stack.
- Previously at Morgan Stanley · NVIDIA · Coupang · iQIYI, from enterprise Java delivery to architecting 0→1 platforms.
- ragflow #18731: DeepDoc document analysis as a native in-process Go backend over statically-linked ONNX Runtime (cgo, dlopen-resolved), with golden-test parity against the Python reference — 3.5px coordinate tolerance, race-detector-verified concurrency, CI drift gate (merged)
- ragflow #18688 · #18707 · #18727 · #18740 · #18789: PDF & table parsing hardening — cross-page table merge, colspan assembly, chunker position handling (merged)
- ragflow #19247: multi-platform native builds (linux/amd64, linux/arm64, darwin) (merged)
- office_oxide #116: table extraction from legacy binary .doc per the [MS-DOC] spec, incl. merged-cell structure reconstruction — shipped as a core feature of v0.1.9 (merged)
- office_oxide #120: list & tab-stop extraction from legacy .doc (ilfo-keyed list detection, sprmPChgTabs decoding) (merged)
