Architecting Resilient, Scalable Web & Cloud Systems

Healthcare administration suffered from fragmented manual appointment booking, delayed financial reporting, and lack of secure role-based medical access.

Engineered a full-stack Next.js and Express platform featuring complex MongoDB aggregation pipelines for 16 operational KPIs, automated token rotation, and 15-role RBAC.

Streamlined clinic administration, automated booking lifecycles, and established compliant clinical data access with sub-second aggregate metrics.

Opaque OPD clinic queues caused 45+ minute patient bottlenecks, crowded waiting rooms, and uncoordinated transfers between consultation desks.

Built a real-time hospital queue engine with sub-50ms WebSocket state syncs, dynamic routing logic, and PostgreSQL Row-Level Security.

Reduced patient waiting room duration by ~65%, eliminated queue token desync, and enabled seamless automated doctor-to-pharmacy patient handoffs.

Decades of cultural literature and spiritual media required high-throughput streaming, global searchability, and values-aligned community interaction without commercial clutter.

Architected a Next.js/Socket.IO platform with Redis caching, Cloudinary HLS streaming, Cloudflare R2 storage, Meilisearch, and Razorpay workflows.

Preserved five decades of cultural heritage, enabled sub-100ms full-text search, and delivered smooth multimedia to thousands of active community members.

Brick-and-mortar retail counters suffered from sluggish checkout queues (90+ sec/cart), manual barcode lookup errors, stock desync, and revenue halts during internet outages.

Engineered a rapid-checkout POS desktop/web software with keyboard-first SKU lookup, offline-first IndexedDB transactional queueing with automatic cloud re-sync, and WebUSB thermal printing.

Slashed average counter checkout duration from 90s to under 18s per customer, processed 5,000+ offline-to-online transactions without data loss, and prevented stockouts across 1,000+ SKUs.
