Hi, I'm Chris 👋

Principal Engineer at Tyler Technologies Public Safety, based in Metro Detroit.

I build on AWS and write about what I learn at chrisebert.net. Lately most of my time goes to:

  • ☁️ Serverless & AWS — Lambda, CDK, and the cost/performance tradeoffs that come with them
  • 🤖 Agentic development — Claude Code, Amazon Bedrock, and getting real work out of AI coding tools
  • ✅ Automated testing — because the interesting part of shipping is knowing it still works

Things I've built

Project What it is
cache-ttl-analyzer Should your Claude Code sessions cache for 5 minutes or an hour? Point it at your session logs and find out. Live at cacheanalyzer.com.
aws-lambda-performance-benchmarks Lambda Arm (Graviton) vs. x86 across Python, Node.js, and Rust on currently supported runtimes — a 2025 refresh of the classic AWS benchmark.
examples-ai-bedrock-agent-national-parks A Bedrock agent that answers questions about U.S. national parks, deployed end-to-end with AWS CDK.
antzer A Frogger-style arcade game my eight-year-old designed, vibe-coded with Amazon Q Developer CLI. Play it.

Writing

A few posts I'd point people to first:
