Description :

Designed and built a production-grade SaaS platform that automates L1 customer support using AI-driven semantic search and multi agents orchestration. Architected a FastAPI (async) backend with PostgreSQL, Redis, and ClickHouse for OLTP/OLAP separation, integrated Pinecone + Voyage AI for multi-tenant vector search (RAG and per-product namespace isolation), and built an n8n workflow engine to route queries through confidence-scored decision trees (auto-resolve, clarify, or escalate). Implemented JWT/OTP authentication, multi-context roles, adaptive document chunking (PDF/DOCX/CSV/MD), real-time analytics dashboards , and ticketing integrations (Jira, Zendesk, Linear, Slack, Discord).
