Overview

Jain Parichay is a matrimony service. I was the software developer who built it during college in 2024 and kept it running — code and infrastructure both.

v1 (live at jainparichay.in) is an Express/EJS + Redis app that circulates biodata profiles as PDFs: Google-OAuth admin, Google Drive to S3 sync, token share-links, and a streaming PDF viewer. It serves real monthly traffic. v2 (at v2.jainparichay.in) was a ground-up NestJS/Astro rewrite into a full matrimony product.

Features

Biodata-import pipeline (v2)

  • Temporal workflow + LangGraph state machine.
  • Azure Document Intelligence OCR (local fallback) -> OpenAI GPT-4o-mini structured extraction -> photo extraction -> Postgres profile, with duplicate detection.

Matrimony platform (v2)

  • typed tRPC API (17 routers), phone-OTP auth (Twilio), Razorpay payments.
  • profile search, interests/matches, messaging, verification, trust & safety and a Kundli/Guna-Milan engine.
