I have 15 years of experience with Python however in this project, I didn't coded anything. Just Vibe coded. Putting errors from the console into chat.<p>Claude 3.7 Sonnet Thinking model used in this (using Github Copilot).<p>Documentation is also available at <a href="https://email-deliverability.readthedocs.io/en/latest/" rel="nofollow">https://email-deliverability.readthedocs.io/en/latest/</a> which is also fully vibe coded.<p>Even the architecture diagram (<a href="https://email-deliverability.readthedocs.io/en/latest/overview.html#architecture" rel="nofollow">https://email-deliverability.readthedocs.io/en/latest/overvi...</a>) is also vibe-coded into mermaid diagrams.
