Jain Parichay
Jain Parichay's matrimony platform. v1 (biodata-PDF circulation) is live; v2 — a full NestJS/Astro rewrite with an automated biodata-import pipeline — was in development. I was the software developer who built and ran it.
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.
Key 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.

FDC WhatsApp Cheque Bot
A WhatsApp bot that reads photographed cheques with GPT-4o Vision and posts receipt vouchers straight into Busy accounting — the part I built independently on a team project.

A real-time 3D wall-visualization tool: a wall photo plus drawn measurements become a Blender 3D model and an itemized bill of materials. I contributed specific improvements to an existing system.
