Work experience & achievements

Led the end-to-end design and deployment of an AI-powered conversational platform integrating real-time voice assistants, chatbot workflows, and retrieval-based search systems. • Built a real-time voice booking assistant leveraging ElevenLabs Conversational AI, WebSocket streaming (PCM16 @ 16kHz), VAD, barge-in detection, and queued TTS, deployed across Flutter and web applications. • Developed LLM-powered support tools (summarization, smart replies, semantic FAQ search) using LangChain, OpenAI API, and Hugging Face models, reducing human operator load by ~55%. • Architected RAG pipelines combining pgvector, Pinecone, and FAISS for semantic retrieval, improving FAQ search precision and task resolution speed. • Extended and optimized backend APIs and microservices (FastAPI, Django, Node.js) with advanced caching (Redis), async task queues (Celery), and optimized query performance for high-traffic environments. • Designed privacy-first data ingestion pipelines with RBAC, encryption, and
