Production platform for WhatsApp, Instagram, and Messenger AI automation targeting Indian SMBs. Built solo, end-to-end: FastAPI backend, Next.js dashboard, ARQ async task workers, Supabase pgvector for semantic memory, Sentry observability, multi-tenant data isolation with Row-Level Security, and a 4-phase Meta OAuth architecture with Fernet AES-256 token encryption. Resolved production failures under live traffic — InFailedSQLTransactionError cascades, Pydantic annotation import conflicts, webhook token flow mismatches, and Facebook post-ID format edge cases.
Temporal RAG system answering how documents change over time — not just what they say now. Semantic diff engine with greedy one-to-one chunk matching, causal graph correlated with 24 regulatory events, 15-pattern PII/secrets scanner, prompt injection detection, append-only audit logs, and Ebbinghaus salience decay.
19-agent Python orchestration platform built without LangGraph or CrewAI — from scratch to understand the internals. Specialized agents with tool calling, persistent shared memory, dynamic LLM routing by task type, and a Flask REST interface.
60-second lead-to-call pipeline deployed for a real client. Tally form → n8n webhook → Airtable CRM enrichment → AI-drafted Gmail outreach → VAPI AI voice call, all within 60 seconds of lead capture. Replaces a fully manual sales process end-to-end.
