Contact

Questions, corrections, and professional conversations are welcome.

The best way to reach me is through LinkedIn. Please include the article title or topic if you are sending a correction, question, or idea.

Use this for corrections, professional conversations, and thoughtful technical discussions.

Corrections

If you notice a factual issue, unclear explanation, broken link, or outdated reference in an article, please share the page title and the specific section so I can review it.

What helps when you reach out

For technical corrections, the most useful note includes the article title, the sentence or diagram that needs attention, and a reference I can check. For article ideas, I am more likely to respond when the topic has a practical production angle: a failure mode, a tradeoff, a migration lesson, or a decision teams regularly struggle with.

Professional conversations

I am most interested in discussions around software architecture, distributed systems, data platforms, Java, reliability, performance, and engineering leadership.
