About

I am a senior software engineer who ships production code in the open. Magento 2 is where most of the recent modules originate, but the underlying engineering — performance, architecture, integrations, platform thinking — applies more broadly, and this site itself runs on WordPress with a custom block theme and an MCP-driven publishing pipeline.

Everything published here comes from real projects. The modules are open source and runnable today; the notes are field observations that survived contact with production.

Working together

• Use any module published under github.com/brosenberger, and open an issue or pull request on the one you need help with.
• For small businesses I take on a few side projects a year: WordPress sites, MCP servers and integrations between tools. What that looks like.
• Anything else: the contact page.
