Projects that i've been working on
A sophisticated chatbot utilizing a FastAPI backend and Next.js frontend, integrated with Gemini API and HuggingFace embeddings. It leverages ChromaDB/AstraDB for retrieval-augmented generation from PDF and PPT documents.
View ProjectAn AI system that learns handwriting from samples to generate realistic assignments with natural variation. It exports directly to PDF and can simulate different pen styles.
View ProjectHardware crossover projects involving ESP32-CAM testing, signal scaling, Time-Division Multiplexing (TDM) demonstrations, and Arduino-based communication systems.
