The Flutter app deployed on Firebase calls a backend deployed on Render, and I built an AI chatbot that can answer pricing questions like the price for 7500 units of C4 envelopes. The agent uses tool calling and a pricing calculator to return exact figures without hallucinations, and it can compare C4 and DL pricing. I also implemented a Tender Scraper that scores government websites from 0 to 100 using keyword matching and LLMs. No specific action was requested from viewers."}
