Personal writings on cloud, code, and whatever else I'm tinkering with.
I built a Grafana dashboard to track AWS costs. The Cost Explorer API calls ended up costing more than all other AWS services combined. Here's what happened and how I fixed it.
How I replaced a Node.js + Socket.io + Kubernetes deployment with API Gateway WebSocket, Lambda, and DynamoDB, cutting costs to near-zero while improving reliability.
How I added full business metrics to a serverless AWS app without any additional infrastructure cost. A CronJob queries CloudWatch Logs Insights and pushes structured events to Loki: totals, trends, and distributions in Grafana.
A real story from an enterprise platform team split over infrastructure tooling. The technical debate was the easy part. The human side, sunk cost, identity, and fear of starting over, is where it gets hard.
