Credit Risk Scoring Engine

Full-Stack ML Platform

  • Trained LightGBM on 176K Lending Club records, reaching AUC 0.7425 vs a 0.7170 logistic baseline; GPU-accelerated via CUDA with SMOTE, validated with bootstrap CIs and a Wilcoxon signed-rank test across 5-fold CV.
  • Engineered an 8-class corporate credit-rating model (AAA–D, S&P-aligned) with 67.2% exact accuracy and 94.9% within-1-notch; integrated a Basel III stress-test simulator with per-request SHAP explainability over REST.

DocuMind — RAG Document Chatbot

GenAI · Retrieval-Augmented Generation

  • Built a Retrieval-Augmented Generation chatbot that answers strictly from uploaded documents (PDF, TXT, Markdown, DOCX) with expandable citations — document name, page, and excerpt — to eliminate hallucination.
  • Chunks documents at 500 tokens and embeds them with all-MiniLM-L6-v2 into ChromaDB; queries run a top-4 similarity search feeding a word-by-word streamed Groq Llama 3.1 response, orchestrated end-to-end with LangChain.

Explainable Multi-Modal Deep Learning

Capstone · Human Activity Recognition

  • Designed a gated-fusion architecture reaching 96.64% accuracy, beating single-modality baselines by 14%.
  • Stress-tested under 10–30% noise with 18% higher accuracy retention; generated per-modality SHAP and Grad-CAM explanations on GCP Vertex AI.

Insurance Risk Advisor

Deployed GenAI + ML App

  • Built an end-to-end RAG pipeline using a ChromaDB vector store and sentence-transformer embeddings; extended it with a LangGraph agent that routes between vector search and web search; deployed on Hugging Face Spaces.
  • Trained a multi-class risk classifier on 50K+ records reaching 87% vs a 72% logistic baseline; deployed on AWS with real-time scoring, data-drift detection, and automated retraining triggers.

Experience

Jul 2023 – Jul 2024

Software Developer Intern @ Sourcved Technologies

Ahmedabad, India

  • Integrated ML inference endpoints into REST-API-driven web apps; traced data flow from model backend to UI and identified 3 classes of serialization bugs causing silent data loss in prediction pipelines.
  • Cut UI defect rate by 40% over two release cycles via a pre-merge browser-matrix checklist (Chrome, Firefox, Edge), improving reliability of ML-powered feature rollouts.

Jan 2023 – May 2023

MERN Stack Developer Intern @ Arth Infosoft Pvt. Ltd.

Ahmedabad, India

  • Designed MongoDB schemas with optimized embedding vs referencing strategies for high-throughput workflows; built REST endpoints feeding structured data into analytical dashboards and React front ends.

Aug 2024 – May 2026

Student Manager @ University of Connecticut Dining Services

Storrs, CT

  • Managed scheduling, payroll, and onboarding for 40+ student employees; used data analytics to optimize shift allocation and cut scheduling conflicts by tracking attendance and peak-demand patterns.
