Production-grade URL shortener built for extreme traffic. Generates 4-character Base62 shortcodes via sub-millisecond Redis INCR, decouples click logging through RabbitMQ for instant 302 redirects, keeps hot URLs cached in Redis, and uses Cassandra for horizontal scalability to millions of requests per second. Load-tested with k6: p99 under 100ms at zero error rate with 200 users/second.

Simulated payment gateway built with an event-driven, containerized microservices architecture. Features Nginx least-connection loadbalancing across two instances per service, RabbitMQ async decoupling with dead-letter queues, per-service PostgreSQL isolation, idempotency via requestId, and a full observability stack with Prometheus, Loki, and Grafana.

WhatsApp-inspired real-time messaging application built with PHP Swoole and Redis. Supports private messages, public chat, typing indicators, delivery receipts, and online user tracking over WebSocket.
