At Acuvelocity India Pvt Ltd, I developed and maintained Python and FastAPI backend applications, including RESTful APIs and PostgreSQL integrations. I also implemented JWT authentication and authorization, and integrated STT, TTS, and RAG capabilities for conversational AI applications.
I developed a semantic search API using FastAPI, PostgreSQL with pgvector, and Sentence Transformers, reaching approximately 1500 QPS. I also built a document chatbot with LangChain, LangGraph, Google Gemini, and ChromaDB to answer questions from uploaded PDFs.
