Python and Generative AI Engineer at VCTI who developed services for the ZOYA Hybrid RAG Platform and ADK-based search.

At VCTI, I developed Python and FastAPI services for the ZOYA Hybrid RAG Platform, connecting query processing, document retrieval, and LLM response generation.

I supported PDF ingestion, text extraction, metadata handling, and configurable document chunking. I also integrated embeddings, vector indexing, and semantic search to retrieve source passages for question answering.

At VCTI, I developed ADK-based product and order search workflows, with backend query orchestration and BigQuery-backed retrieval. I diagnosed pipeline and response issues by reviewing processing status, intermediate outputs, and conversation history.

At Luna Software Solutions, I built Python REST APIs and backend services, including document-based RAG question answering, a client help chatbot, and voice-assistant APIs. I also implemented a Flask workflow synchronizing MySQL and ChromaDB data and settings.
