Afshan Qasim

I build distributed, production-grade systems - not just web apps. Currently focused on cloud-native backend engineering: event-driven architectures, container orchestration, and systems that survive real-world failure conditions.

Projects

Sentinel-SRE · Distributed Uptime Monitor

Production-grade distributed system monitoring website health at scale.

  • Zero data loss under worker failure — RabbitMQ Manual ACKs + Dead Letter Queues + Exponential Backoff
  • Sub-millisecond status lookups — Redis caching layer cuts PostgreSQL read I/O dramatically
  • Full observability — Prometheus + Grafana dashboards tracking P99 latency per endpoint
  • Load verified — k6 stress tested at concurrent user load to identify breaking points before production

Go Node.js RabbitMQ Redis PostgreSQL Prometheus Grafana Docker k6

Link Vault · Kubernetes-Orchestrated Asset Manager

DevOps-first MERN application built for production-grade Kubernetes deployment.

  • Self-healing infrastructure — Kubernetes automated pod recovery and restart policies
  • Config decoupling — Kubernetes Secrets + ConfigMaps for clean credential isolation
  • Optimized images — multi-stage Dockerfiles for lightweight production containers
  • Live monitoring — Prometheus + cAdvisor + Grafana dashboards for real-time resource visibility
