About Michael

I help agencies and digital companies get their PHP systems technically in shape: faster, more maintainable, future-proof.My focus is on performance optimization, realtime functionality, and technical architecture reviews.

In practice, this means: systematically identifying and eliminating performance bottlenecks, with measurable results instead of vague promises. Drastically reducing loading times and server response times through targeted use of SSE, Brotli compression, ETags, and consistent caching. Implementing real-time features that integrate cleanly into existing systems without introducing a JavaScript build stack that burdens the team long-term. Developing APIs and interfaces between existing systems that remain maintainable in the long run. Conducting technical audits that provide concrete recommendations for action instead of generic inventories.

I work server-oriented and deliberately keep technical complexity low. Where others introduce a React frontend layer, SSE and cleanly structured HTML are often sufficient. The result: fewer moving parts, simpler deployments, lower operating costs. On the infrastructure side, I work with systemd, docker, caddy, and nginx.

I take full responsibility, from analysis to go-live. No ping-pong between teams, no half-finished handovers.Projects are handled at fixed prices: clear scope, clear costs, no nasty surprises.

My work results in open-source contributions:
  • php-via (via.zweiundeins.gmbh) is a realtime PHP framework based on OpenSwoole and SSE, enabling reactive multiplayer applications without JavaScript and without a build step.
  • php-geobuf (github.com/mbolli/php-geobuf) is a PHP library for the compact Geobuf geospatial data format.
