Monitoring and alerting stack I built for production Kubernetes on AWS EKS. It cut mean time to resolve incidents (MTTR) by 50%, log storage cost by 70%, and alert volume by 60%, with Prometheus, Loki, Grafana OnCall, and external HTTPS probes.
Live multiplayer quiz SaaS built as a Go game server and a Python API with a React frontend, Stripe subscriptions, and GitOps deploys on Kubernetes. Load-tested to 30,000 concurrent players on two game pods with zero errors.
A video conferencing platform I designed and built on AWS at CraftSchoolship, running the open-source BigBlueButton software as an auto-scaling fleet. A custom machine image cut server launch time from 11 minutes to 3, and scale-in protection keeps live meetings running while the fleet shrinks.
