VitalTrace
Personal Health Record Intelligence & Deterministic Data Quality
Full-stack clinical data intelligence system that ingests unstructured lab reports, executes deterministic physiological validation, normalizes test aliases to LOINC standards, and tracks longitudinal biomarkers with zero hallucination tolerance.
45 Vitest Specs Passing
- ▸Engineered deterministic clinical validator engine enforcing biological plausibility bounds and unit standardization.
- ▸Zero-hallucination LOINC code mapping: unrecognized tests retain raw string names with null codes.

DocMind AI
Hybrid RAG Document Intelligence Platform with Page-Level Lineage
Enterprise document question-answering and synthesis engine combining FAISS dense vector search with BM25 sparse keyword matching via Reciprocal Rank Fusion, exact page citation pills, and dual Groq/Ollama inference backends.
Dense + Sparse RRF Engine
- ▸Designed hybrid retrieval pipeline using Reciprocal Rank Fusion (RRF) to merge dense semantic and sparse lexical search.
- ▸Engineered word-to-page boundary chunking guaranteeing zero-loss citation traceability to exact PDF pages.

WorkWise
Climate-Aware Construction Task Scheduling Engine
Predictive thermal strain and occupational safety platform for Indian construction operations, replacing crude clock rules with Liljegren (2008) physical WBGT modeling, CAQM GRAP regulatory constraint scheduling, and Bedrock AI briefings.
48/48 Pytest Passing
- ▸Engineered physical heat-stress engine using peer-reviewed Liljegren (2008) formulation to calculate Wet-Bulb Globe Temperature.
- ▸Strict architectural separation: deterministic Python safety engine decides constraint gates; Bedrock LLM only explains.
