Architected and built Conversational AI Search (Ask Astra), a ChatGPT-style enterprise AI assistant using React, TypeScript, API-driven architecture, and real-time streaming for natural-language search across organisational knowledge. Integrated LLM-powered retrieval (RAG) pipelines, working with backend services to design prompt templates, context-retrieval endpoints, and token-efficient request/response contracts between the frontend and the LLM-serving layer. Designed a scalable component design system and Storybook library for the AI platform, building reusable and accessible components including Buttons, Tooltips, Modals, Bottom Sheets, inputs, and conversational UI components, improving consistency and accelerating development across AI workflows. Designed a scalable conversational UI supporting multi-turn context, streamed AI responses, conversation history, resource switching, response regeneration, feedback workflows, and asynchronous AI interactions. Integrated AI services, backend APIs, real-time data streams, and asynchronous workflows, handling streaming states, retries, errors, and conversation state for reliable AI experiences. Worked with backend teams on microservices-based API architecture, improving p95 response latency for search and conversational endpoints through caching strategies, payload optimization, and request batching. Designed and developed an in-house Internal Ticket Management System, replacing Zendesk with a scalable role-based platform supporting ticket lifecycle management, prioritization, assignment, and customer-worker collaboration, eliminating third-party dependency and reducing annual support tooling costs by an estimated 20–30%. Built a voice bot for customer support using Sarvam AI, enabling AI-based query resolution and triage before escalation to human support agents and improving initial response time by an estimated 40%.
