    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.

    "Top Rated by Upwork" Hello my name is Oscar Q. I'm a Web / WordPress Developer and I've been with Upwork/oDesk for +15 years. My websites vary from smalls business to international agencies. I am able to code within the following areas: HTML5, CSS3, Jquery, PSD/Figma/Sketch to WordPress theme, slicing PSD/Figma/Sketch files into table-less HTML5/CSS3, and PHP/Laravel. Also able to create AWS instance/Digital Ocean droplet to host website and web application. From the different function that I provide, I incorporate "responsive web design" aimed at crafting websites to be smartphones and tablet friendly. My web projects are cross browsers compatible with MS Edge, Chrome, Firefox, and Safari. I thrive for user-friendly and lightweight website to archive your business goals, by attracting more users. I can bring to life pre-existing web design and convert it into a WordPress website so you can manage it without a programmer at your side, or develop a new design as your needs require. Clean and beautiful designs are created to attract new client to your business or increase the traffic of clients into your website. I can transform website site from a good site to an outstanding one. Look forward on working with you.

At A Glance: Ubuntu

Ubuntu is an open-source operating system designed to connect the digital arena to a single secure, simple, and effective system. The word “Ubuntu” translates into “humanity to others,” which is illustrated in the system’s abilities to work on many different devices and computers. That makes it easy for personal, business, or educational initiatives to gather together information, programs, and projects on one system. Installing and utilizing the many features of Ubuntu can help your business thrive in collaboration and communication like never before.
