Senior WordPress developer // frontend systems // Michigan
I’m Marcus Borger. I build custom WordPress platforms, plugins, and interfaces—then trace the weird problems from browser to database when production gets dramatic.

Michiganavailable for practical web work
Calm engineering. Loud execution.
GermanyMichigan
Practical, curious, and allergic to fragile systems.
I'm a German-born web developer living in Michigan, with a background in applied computer science from Hochschule Merseburg and more than a decade of professional web experience.
My day-to-day work spans custom themes, plugin development, ACF-powered content structures, multisite support, frontend styling, GitHub-based release workflows, and debugging when websites get strangely confident about being wrong.
I build sites that are clear to use, easy to manage, and sturdy enough to survive clients, plugins, updates, caching layers, and the strange weather patterns of the modern web.
What I Do // Machine modules
Strategy is useful. Shipping is better. I work across the whole stack when that is what the problem demands.
MODULE_02ONLINE
Frontend Implementation
Responsive HTML and CSS, Tailwind, SCSS, JavaScript, and jQuery—carefully implemented on desktop and engineered not to collapse into soup on mobile.
MODULE_03ONLINE
Debugging & Maintenance
PHP errors, caching weirdness, CSS regressions, migrations, release issues, server oddities, and production problems that need calm investigation.
MODULE_04ONLINE
Workflow & Infrastructure
GitHub release workflows, cPanel and WHM troubleshooting, multisite support, database work, API integrations, and practical deployment handoffs.
Selected work // Real constraints
The visuals can get loud. The work stays grounded: real editors, real data, real deadlines, and systems built to survive all four.

Good development is not just writing code. It is understanding the workflow, reducing friction, and building something future humans can understand without needing a torch and a map.
I prefer clear structure, thoughtful defaults, maintainable code, and honest communication over complexity for its own sake. When something breaks, I want to know why, who it affects, and how to keep it from becoming a recurring calendar event.
