About

I'm a Data Analyst and AI/ML Engineer who loves turning raw data into clear insights and building intelligent systems that solve real problems. 🔹 On the Data side, I work with Python, SQL, Power BI, and Excel to design dashboards, automate reporting pipelines, and help teams make faster, better decisions. 🔹 On the AI/ML side, I build and deploy machine learning models using TensorFlow, and develop LLM-powered applications with RAG (Retrieval Augmented Generation) architectures and FastAPI backends. What drives me is the intersection of data and intelligence — where a well-built model or a clean dashboard can genuinely change how a business operates. 🛠 Tech Stack: - Languages: Python, SQL - BI Tools: Power BI, Excel - ML/AI: TensorFlow, Scikit-learn, LLMs, RAG Systems - Backend: FastAPI - Other: Data Visualization, ETL, Reporting 📍 Based in Bilaspur, Chhattisgarh | Open to remote & hybrid roles across India 💬 Feel free to connect if you're working on data-driven or AI projects — I'm always up for a good conversation.

Projects

RAG Chat Agent

Designed and built a local RAG-based chat agent to retrieve, analyze, and summarize official documents using LLM-powered reasoning. Implemented real-time document retrieval with tool-assisted responses and an asynchronous FastAPI backend. Technologies: Python, FastAPI, MySQL, Ollama (Qwen2), AsyncIO, HTML/CSS, JavaScript.

Recommendation System

Developed a product/content recommendation engine using collaborative filtering techniques. Used LightFM and Scikit-learn to model user-item interactions and generate personalized suggestions. Technologies: Python, TensorFlow, LightFM, Scikit-learn, Pandas, Matplotlib.

Sales Performance Analysis

Analyzed large sales datasets to surface trends, top-performing products, and regional performance gaps. Created visual dashboards and automated reports to support data-driven business decision-making. Technologies: Python, SQL, Pandas, Matplotlib, Seaborn, Excel.

Object Detection Pipeline

Implemented an object detection system to identify and label objects in images using bounding boxes. Improved model detection accuracy through iterative tuning and result visualization with OpenCV. Technologies: Python, OpenCV, TensorFlow, Matplotlib.
