## Projects

### LinkedIn Outreach Automation
4-workflow n8n pipeline using Apollo.io for lead discovery and Unipile API for LinkedIn messaging. Runs daily personalized outreach, tracks acceptance, sequences follow-ups, and routes replies to Telegram.

### Newspaper Intelligence Extraction
Automated system that downloads 39 editions of Gujarati print newspapers daily, runs OCR via Gemini Vision, and extracts 5 signal types: tenders, property transactions, business openings, court records, and political appointments. Addresses a gap in the Indian B2B intelligence market — digital tools only cover eProcurement portals, missing print-only notices.

### Astrology AI Persona
RAG system built on 1,224 YouTube transcripts. Pipeline: transcript download → text chunking (400 words, 50-word overlap) → Gemini embedding (gemini-embedding-001, 3072 dimensions) → pgvector in Supabase → hybrid retrieval → persona-tuned inference.

### Cold Email Infrastructure
Full-stack cold email system: SPF/DKIM/DMARC configuration, mailbox warmup, Apollo lead sourcing, NeverBounce validation, n8n orchestration, AI copy generation via Gemini, Instantly/Smartlead delivery.

### Gujarat Court Case Intelligence
Python-based court case monitoring system using the ecourtsindia.com API (600+ courts). Polls for hearing date changes and sends proactive WhatsApp/Telegram alerts. Targets law firms and businesses tracking litigation.
