AI assistant
Ask about Michał's work
I'm the AI assistant on Michał's site. I answer questions about his work using only what is published here. I can make mistakes, and I can't speak for him on rates, availability or anything confidential. For those, or whenever I get stuck, you can message him directly.
Recruiters: paste a link to a job offer, or its description, and I'll give an honest estimate of how well it fits Michał's published experience, including what this site does not document.
Messages are processed by Anthropic (Google if Anthropic is unavailable) to generate answers. Please do not share confidential or personal information. See the Privacy notice. Conversations are stored for 90 days; one you share or send, and an evaluation page you open, are kept for 12 months.
I use a few cookies to keep the site working and, with your permission, to understand how it is used, to load the scheduling widget and to play videos in articles. You can change your choice at any time.
