My name is Reinir Puradinata. I am a PHP and Java coder with a focus on high performance.
An example of what I can do is ReiRouter: a simple request router that is many times faster than FastRoute, even though it is not optimized. In case you don't know, FastRoute is considered by many as the fastest PHP request router there is.
Grab the source code here and find out how it works before I optimize it into a cryptic mess of really fast code.
Email me if you want to discuss high performance strategies or if you just want to say hello.
