Oakland Building Faster With Claude Code
Mon, Oct 19, 3:45 AMWe are hosting an informal session in Oakland focused on getting hands-on with Claude Code. The goal is to move past the basics and explore how to integrate this tool into your daily workflow to speed up development tasks, manage complex refactoring, and handle routine debugging more efficiently. Whether you have already started experimenting with it or are just curious to see how it performs in a real-world project, this is a space to compare notes and troubleshoot together. This session is designed for developers who are already comfortable with the command line and are looking to sharpen their AI-assisted coding skills. We will keep things collaborative, so bring your laptop and a project you are currently working on—or just bring your questions. We will spend the time sharing tips, discussing best practices for prompting, and working through common hurdles in a relaxed, peer-to-peer setting. If you are planning to come by, please take a moment to RSVP so we can get an accurate headcount for the space. We look forward to seeing everyone there and figuring out these new tools together.
