The best way to contact me is by email at ryan.zidago@protonmail.com. I read messages personally and reply when a response would be useful.

I welcome thoughtful questions and conversations about product engineering, AI-assisted software development, automated code review, executable engineering guardrails, Elixir, and the articles published on this site. If you are writing about or citing an article, please include the article title or URL so I can understand the context. For a project or collaboration, include the problem you are trying to solve, the expected outcome, and any relevant timeline.

Please do not send unsolicited sales pitches, bulk marketing, requests to buy links, or requests for paid placement. This is a personal website, not a customer-support portal, and it does not offer accounts or paid services. Never send passwords, API keys, confidential source code, personal identification documents, or other sensitive information by email.

You can also find my public work on GitHub and my professional profile on LinkedIn. Those profiles are useful for background, but email remains the preferred contact method.
