I specialize in infrastructure using terraform on aws and proxmox as well as kubernetes via flux in IaS environments. 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.

I’ve been referred to as a Full-Stack developer, but my interests and experience extend far beyond the typical frontend-backend divide. While I have plenty of stereotypical Full-Stack experience—such as delivering custom company websites, web portfolios, RESTful API's, and internal company tools—my expertise goes much further. In fact, I’ve gained a breadth of experience that seems uncommon among my peers who share the same title. Here are a few of my favorite examples that tend to stand out with my Full-Stack peers: -Demonstrated cross-language interoperability between COBOL, Fortran, C, and JavaScript delivered in WebAssembly -Implemented automatic trading algorithms in MATLAB with Ninja Trader -Developed embedded systems for device management and real-time monitoring -Built a custom logic simulator in Rust -Modified and daily-drove a mobile Linux distribution as my primary smartphone operating system -Designed processor components at the electronic level, including cost analysis, speed optimization, and gate propagation. Comfortable working independently or as part of a team, with experience across multiple levels, including leadership roles.

I have a broad base of technology expertise including web application development, hosting, networking, infrastructure and security. I have worked on startup technologies all the way up national brands and enterprise scale deployments. I have been in senior/executive roles in technology for the last 10 years, but I love to keep my hands dirty. I'm happy to help you with technology and security leadership or just help you troubleshoot a web site, broken server or whatever else you got. I have worked with Linux and full stack application development for over 20 years. I primarily work with AWS and co-located or on-premises infrastructure. I am also a big advocate of any automation or infrastructure-as-code methods (ansible, teraform etc.). I am well versed with CI/CD concepts, tools and workflows. My rates are pretty flexible depending on the task and time commitment. Feel free to reach out with any questions.
