Architected and engineered production-grade internal business tools, operational dashboards, and real-time management platforms with a strong focus on hospitality and service operations. Key Achievement - Multi-Tenant Real-Time Guest CRM & PMS Operations Platform: • Architecture & Backend: Designed a scalable multi-tenant backend using Django, Django REST Framework, and PostgreSQL with strict tenant-isolation models and database-level constraints. • Real-Time Communication: Implemented asynchronous bi-directional messaging using Django Channels and Redis channel layers for zero-latency guest-to-staff interactions. • Frictionless Client Onboarding: Engineered a QR-based frictionless session lifecycle utilizing client-side UUID persistence, seamless reconnection algorithms, and safe session archiving on checkout. • Operations Cockpit: Built a fully responsive operational dashboard featuring instant guest tagging (VIP, Repeat Guest), canned response triggers, and multi-language communication pipelines. • Production & Reliability: Isolated sensitive configs via environment variables, optimized ORM queries against N+1 bottlenecks, and integrated robust rate-limiting and connection-recovery handlers.
