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, platform thinking — applies more broadly.

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.

How I can help

• Performance and image delivery: faster category and PDP pages, real LCP wins.
• Content Security Policy: safer rollouts with smaller blast radius.
• Maintainable customization: entity services instead of scattered preferences and plugins.
• Operations clarity: store overview and chart-driven telemetry for multi-store setups.

Who I work with

• Magento 2 tech leads and CTOs on multi-year projects.
• Agencies inheriting Magento codebases with accumulated customization.
• Operations and merchant teams running multi-store setups.

How to engage

• Use any module published under github.com/brosenberger.
• Open an issue or pull request on the module you need help with.
• Reach out via the contact page for tailored guidance or implementation support.
