Fresh MicroVM took 26s to mount a home directory. The mount itself was 0.6s — the rest was demand-paging the toolchain from snapshot storage at ~3MB/s. Fix: put the mount stack into tmpfs (anonymous memory survives snapshot capture, page cache doesn't). Got it to 11s. Lessons generalize to any snapshot-booted compute.

Built a browser-based Claude Code sandbox on Lambda MicroVMs + S3 Files. Open a tab from iPad or laptop, land in a shell, close it, come back later — files and session intact. MicroVMs suspend when idle ($0 compute), S3 Files persists the home directory. One SAM template deploys everything. ~$10-37/mo. Full source on GitHub.

A honest walkthrough of building a production event-driven microservices platform from scratch using ECS Fargate, EventBridge, SQS, SNS, Terraform, and GitHub Actions OIDC. No templates, no shortcuts, just real failures across infrastructure, CI/CD, networking, and application logic, and exactly how each one was fixed. Built so you can learn from the mistakes before you make them.

This is not a high-pressure coding competition. It is an exploration of what agents can do when they aren't limited by verification codes, making payments, voice calls in a different language, and so much more.
