About

I build AI-powered data systems that turn messy, unstructured information into decisions. Currently a Data Analytics & AI intern, I've shipped production-grade systems including: • A retrieval-augmented generation (RAG) chatbot using LangChain + LLaMA 3.2 for intelligent NLP-based query resolution • A multi-platform web scraping pipeline (Amazon, Flipkart, JioMart, Tata 1MG + 2 more) for competitive tea pricing — integrated with Excel via Python automation • An automated PDF data extraction system for structured tax data processing • An enhanced Power BI dashboard (DAX-powered) tracking machine efficiency, operator downtime, and operational KPIs My edge: I don't just analyze data — I automate the pipelines that collect it, clean it, and make it queryable by AI. Tech stack: • Languages & Tools: Python, SQL, Power BI, LangChain, Ollama • AI/LLM: RAG pipelines, LLaMA 3.2, Prompt Engineering, NLP • Data: Pandas, Web Scraping, Excel Automation, DAX Currently pursuing PGDM in Business Analytics at Globsyn Business School (2024–2026). Open to: Forward Deployed Engineer · AI Engineer · Applied AI Engineer · Data Analyst · Developer Advocate Let's connect if you're building something with data and AI.
