Key Projects

LLM RAG for Interview Question Generation

Built a system using LangChain, Gemini Pro, and ChromaDB to generate domain-specific technical and behavioral interview questions from multi-format data (PDFs, YouTube, XLSX), reducing HR workload.

Client Call Summarization & QA System

Designed an AI solution (OpenAI Whisper, LangChain) to summarize client calls and answer queries, enhancing communication between technical and business teams.

Unbiased Content Generation with LLMs

Developed a Generative AI system to create unbiased job descriptions, email templates, leave applications, and feedback, reducing bias in HR communications.

AI Chatbot Development

Created a multilingual chatbot (RASA, GPT-4) for HR activities, simplifying processes such as leave, attendance, and onboarding, and boosting user satisfaction.

ID Card Parsing

Automated ID verification with a fine-tuned ResNet50, a fine-tuned YOLOv5 and EasyOCR, improving accuracy by 98%.

ATS Resume Ranking

Built an ATS to rank resumes using NER and graph networks, increasing screening efficiency by 50%.

Attrition Prediction

Predicted employee attrition using ensemble methods (RF, LightGBM, CatBoost), reducing attrition rates by 25%. Integrated proprietary data and IBM datasets.

Behavioral Analysis from Interview Videos

Led a team of 4 to classify candidate traits and emotions using ASR (Whisper-small), BERT, LightGBM, and AWS Rekognition enhancing hiring decisions with reduced bias via a Flask API integration.
