Auction Avenues

India's Institutional Bank NPA & Distressed-Asset Bidding Marketplace (112+ APIs, 4.6 Lakh+ Localities)

Architected and deployed an institutional-grade distressed-asset and property marketplace aggregating bank NPA auctions (under the SARFAESI Act & DRT), verified resale inventories, and rentals pan-India. Engineered a unified Next.js 16 monorepo serving 6+ role-segregated operational portals (Admin, Customer, Broker, Builder, Owner, Architect, Contractor). Features an interactive virtual auction floor powered by Pusher WebSockets with sub-100ms bid broadcasting, multi-layer Upstash Redis caching with SHA-256 query hashing, automated Razorpay recurring billing with server-side GST tax invoice generation via @react-pdf/renderer, and a geospatial ingestion pipeline mapping 468,622+ Indian localities.

Multi-state search gateway, real-time SARFAESI notice aggregation, bank partner trust badges, and 3D property showcase.

The Business Challenge & Market Need

Non-Performing Assets (NPAs) auctioned under statutory frameworks (SARFAESI Act 2002 & DRT) represent tens of billions of dollars in distressed Indian properties, but suffered from acute information asymmetry across physical print newspapers, broker spam, and lack of real-time discovery.

Engineered Solution

Engineered a multi-role monorepo serving 6+ segregated portals (Admin, Customer, and 5 vendor personas: Broker, Builder, Owner, Architect, Contractor). Built proprietary Admin-in-the-Middle PII protection, sub-100ms Pusher live bidding room, and automated GST invoice synthesis via @react-pdf/renderer.

System Architecture Pipeline

Client (React 19 / Next.js 16) → Vercel Edge Middleware (Rate-Limiting + JWE Auth) → Next.js 16 Server Cluster → Upstash Redis (SHA-256 Query Cache) → PgBouncer Transaction Pooler (Port 6543) → Supabase PostgreSQL 16 (54+ Relational Models) + Pusher Channels WebSockets + Razorpay Live.

Key Technical Breakthroughs & Capabilities

Sub-100ms Pusher WebSocket Live Bidding Floor with synchronized countdown timers and anti-sniping extensions.
Admin-in-the-Middle inquiry workflow ensuring zero buyer-broker direct PII exchange prior to fee clearance.
Dual-subscription & automated GST invoice generation (@react-pdf/renderer) compliant with state CGST/SGST/IGST tax routing.
468,622+ locality Indian geographic ingestion engine supporting fuzzy search and coordinate mapping.
Real-World Commercial ROI

Business & Operational Impact

1

Zero-Disintermediation Marketplace: 100% of vendor PII is protected against scraping, preserving the platform's multi-million-rupee commission channels.

2

Pan-India Operational Footprint: Full geographic coverage across 468,622+ verified Indian locations with targeted Phase 1 liquidity across 31 tier-1/tier-2 markets.

3

Enterprise Automation: Eliminated manual notice transcription via bulk CSV upload pipelines with automated coordinate normalization (turnaround cut from 48h to <30s).

4

Zero-Downtime Infrastructure: High-availability edge deployment with PgBouncer connection pooling and Upstash Redis maintaining sub-300ms p95 page loads.
