    I have 21 years of general linux experience with apache, php, bash, python and various other scripting/programming languages. I have 7 years of expert level experience using memcache/redis and nginx application accelerator proxies based on Redhat and Ubuntu with php-fpm, apache, nodejs, java, .net and other application servers. These include zend, wordpress, drupal and several other web software suites In one of my previous projects I was been able to allow for up to 40,000 simultaneous user sessions across twenty apache application servers utilizing nginx reverse proxies, behind several F5 load balancers. Initial hardware was able to accommodate up to 4,000 users. Since the application was not stateless nor was it designed for data segregation between private/public data the nginx rulesets were very complex requiring rewrites, header injections/strips and even body regex find/replaces. I also have expert level experience with large scale wordpress clusters from the file service and db aspects. I have experience with appdynamics, nagios and large scale ELK logging. I have experience with AWS, especially linux EC2 containers, elastic beanstalk and cloudformation. I am highly skilled in troubleshooting complex multi-tier interaction issues using system logs, stack traces and wireshark packet traces.
