Projects
- RAG Resume Matching Agent, Python, Google Gemini API, Streamlit, Built an end-to-end RAG (Retrieval-Augmented Generation) pipeline that screens resumes against job descriptions. Extracts structured candidate data via LLM, generates embeddings, and computes cosine similarity scores to rank resume-job fit; built from direct API calls rather than a framework to deepen hands-on RAG understanding., https://rag-resume-matching-agent-mxy9kpmfx4tfb42w5jttcu.streamlit.app/, https://github.com/iamarindam21/rag-resume-matching-agent
- Titanic Survival Prediction, Python, Pandas, Scikit-learn, Matplotlib/Seaborn, Developed a classification model to predict passenger survival on the Titanic dataset, applying exploratory data analysis (EDA) and machine learning algorithms to identify key survival factors.
- Data Visualization Dashboard, Power BI, Excel, Created interactive dashboards and visual reports to analyze and present data-driven insights, translating raw datasets into clear, business-friendly visuals.
