Dual-Ecosystem Mobile & Ambient AI Clinical Scribe
Ambient Clinical Intelligence & Dual-Ecosystem Healthcare
An end-to-end, zero-trust ambient clinical intelligence healthcare platform designed to eliminate doctor documentation burnout. Captures verbal consultations to generate structured SOAP notes with fine-tuned Whisper & Mistral-7B, automated drug-drug safety contraindication scoring, and delivers real-time health vaults across two native Android mobile apps (Doctor & Patient).
Key Highlights
FastAPI · Whisper ASR · Mistral-7B · Expo Native
- Fine-tuned Whisper-Small with LoRA (FP16) and Mistral-7B with QLoRA for automated SOAP note generation (0.92 ROUGE-1)
- Two standalone native mobile applications (Doctor App & Patient App) built with React Native and Expo
- Automated pharmacological contraindication scoring cross-referencing patient allergies and active regimens
- Zero audio retention protocol with in-memory audio shredding and AES-256-GCM encryption at rest

01. Problem
Practicing clinicians face severe administrative burnout spending hours drafting SOAP notes and prescriptions, while patients endure opaque waiting times and struggle to interpret complex medical regimens.
02. Architecture
Engineered a dual-ecosystem mobile architecture: a Doctor App with live waveform transcription and OPD capacity guards, paired with a Patient App featuring passwordless OTP authentication and an AI Health Copilot.
03. Medical AI Pipeline
Implemented an on-premise privacy-first ML pipeline using fine-tuned Whisper for multi-speaker clinical ASR and QLoRA-quantized Mistral-7B-Instruct to convert dialogue into structured medical records with 72/72 passing tests.
04. Security & Compliance
Architected DPDP Act 2023 and HIPAA-compliant zero-trust security: zero persistent voice storage, HMAC-SHA256 blind indexing for private lookups, and AES-256-GCM data encryption.
Outcome
Built a DPDP/HIPAA-compliant healthcare ecosystem featuring live audio consultation transcription, automated SOAP care plans, live OPD triage queues, and a passwordless patient vault.
Demonstrates end-to-end software execution, clean UI polish, and practical problem solving.
