Backend Developer (Project) - Multimodal RAG Assistant

ImageTranscription

You built a multimodal retrieval-augmented generation assistant that supports ingestion and semantic search across multiple media types. You implemented chunking, embeddings, and vector storage to enable efficient retrieval with ChromaDB and local LLM inference via Ollama. You also developed OCR and media-processing pipelines for extracting text from images and converting audio/video using standard tools. • Implement document chunking, embeddings, and semantic search with ChromaDB • Integrate local LLM inference through Ollama and a Streamlit interface • Build OCR pipelines using Tesseract for image understanding • Process media with FFmpeg and audio transcription with Whisper
