Contactless vitals monitoring and triage platform using remote photoplethysmography (rPPG) to extract heart rate, HRV (SDNN, RMSSD), and respiratory rate from smartphone camera input. Streams frames from a Flutter app to a FastAPI backend where MediaPipe FaceMesh + CHROM isolate blood volume pulse signals, with FFT-based analysis for real-time physiological estimation. Integrates a multi-agent Claude pipeline to combine vitals with adaptive symptom intake and generate structured urgency classifications with plain-language summaries.

Biometric-adaptive study platform capturing heart rate, HRV, breathing rate, and blink signals from smartphone camera via Presage SmartSpectra SDK. Streams physiological data over WebSockets to a locally-hosted Qwen 2.5 LLM (Ollama) which classifies cognitive states — flow, fatigue, frustration, disengagement — and generates adaptive study recommendations in real-time. Improved measured study efficiency by 75%.

Multi-persona conversational AI platform engineered on the Google Gemini API, delivering adaptive emotional support through three distinct relational behavioral profiles: therapist, companion, and ex-partner. Implements dynamic prompt engineering with contextual session memory to maintain persona coherence across extended conversations. Features real-time streaming response architecture, emotional state inference from user input patterns, and a Next.js App Router frontend with custom conversation state management hooks.

Chrome extension performing real-time credibility analysis on long-form media sources during active browsing. Implements live DOM parsing and metadata extraction combined with bias-detection heuristics and citation-density scoring. Lightweight NLP models evaluate credibility signals across 1,000+ analyzed pages, surfacing inline reliability indicators and source bias flags — with natural language explanations via a locally-hosted Ollama inference layer.

Comprehensive personal finance management system engineered entirely in Excel VBA. Supports structured data management for 5,000+ financial records with automated categorization pipelines and validated data-entry UserForms enforcing strict schema integrity. Features 10+ automated analytical dashboards — spending trend analysis, net cash flow visualization, investment projections with trained exponential growth models, and budgeting scenarios.
