ResuPulse — AI Resume Analysis Platform
Architected and built ResuPulse end to end, combining seven deterministic analysis engines with eight parallel LLM specialist agents into a unified, high-throughput AI document analysis platform.
- •Asynchronous Multi-Agent Pipeline: BullMQ priority queues with separate concurrency lanes, Redis Pub/Sub for real-time progress streaming, and pre-inference structural PII redaction.
- •Document Ingestion: Complex PDF parsing combining spatial layout geometry, table detection algorithms, and OCR fallback for flattened files.
- •Production Cloud Infrastructure: Deployed on AWS EC2 (Mumbai) PM2 cluster, backed by AWS ElastiCache Redis and Cloudflare edge protection.

Furniture E-Commerce Platform
A dual-application e-commerce platform featuring decoupled customer storefront and seller/admin portals, built with transactional MongoDB sessions, non-blocking Redis cache synchronization, and a catalog-grounded AI shopping assistant.
- •Dual-Application Architecture: Separate customer storefront and seller/admin portals with domain services, repository data access, and validated Zod API boundaries.
- •Atomic Checkout Transactions: MongoDB multi-document ACID sessions with conditional bulkWrite stock updates and idempotent Razorpay HMAC webhook verification preventing duplicate fulfillment.
- •Distributed Redis Caching Layer: Cursor-based, non-blocking SCAN cache invalidation, keeping seller and inventory updates in sync with the customer storefront without blocking the cache.
- •Catalog-Grounded AI Shopping Assistant: Natural-language search, fuzzy keyword matching, autocomplete, and a Groq-powered AI shopping assistant constrained strictly to real inventory.
