I build developer tools and AI-powered products in .NET. This blog is where I write down what broke in production and what I learned. Pick a topic:
Performance & Reliability
- Nothing crashed. My CPU sat at 390%.
- AI wrote a thread-safe counter. The CPU made it 5x slower.
- Behind Cloudflare and nginx, all my users had the same IP
- Split-brain needs a cluster. Mine happened on one server.
AI Engineering
- An AI feature has no “tests pass” moment. So I write the eval first.
- I put Ollama on a 4 GB mobile GPU and got 2.5x
- Nobody alerts on silence: wiring Sentry into an LLM pipeline
- AI Evals, explained (5-part series)
