Showcasing my technical expertise and innovation
A production-grade healthcare platform that combines a dual-model ensemble (Random Forest & XGBoost) to predict heart attack risk based on clinical patient data. The platform features an AI Doctor Assistant powered by Gemini 1.5-Flash with RAG (Retrieval-Augmented Generation) capabilities for analyzing uploaded medical reports.
An end-to-end data analytics and AI application that transforms raw WhatsApp chat exports into deep insights. Features include interactive analytics dashboards, VADER-based sentiment analysis with mood tracking, and an AI Chat Agent powered by Google Gemini that extracts real chat patterns to mimic a person's writing style, vocabulary and emoji usage in Hinglish conversations.

My professional journey in data science
Apr 2024 - Ongoing
* Product Development: Engineered a production-ready, AI-powered health
platform using FlutterFlow for the frontend and Supabase for the backend database
architecture.
* AI Coaching System: Implemented a sophisticated AI health assistant by integrating
OpenAI Assistant APIs and building a custom RAG (Retrieval-Augmented Generation)
pipeline.
* Data-Driven Insights: Developed logic to process daily activity logs and complex
medical
health reports to generate personalized, actionable health recommendations for
users.
* Architecture: Designed the system to serve as a 24/7 personal health assistant,
ensuring
low-latency responses and secure handling of sensitive health data within the Supabase
ecosystem.
Apr 2023 - Jul 2023
* Ensemble Modeling: Developed a high-performance FAQ classification model by leveraging
advanced ensemble techniques to categorize edtech queries.
* NLP Pipeline & Engineering: Engineered a dataset of 6,000+ edtech FAQs, implementing
comprehensive NLP preprocessing and utilizing Transformer architectures for deep
semantic understanding.
* Feature Extraction & Analysis: Employed TF-IDF vectorization and initially trained a
Random Forest Classifier, achieving 74% accuracy in sentiment analysis of user
inquiries.
* Optimization & LDA: Achieved a peak accuracy of 94% through rigorous hyperparameter
fine-tuning and the integration of Latent Dirichlet Allocation (LDA) for sophisticated
topic modeling.
