    Systems Engineer

    United States - Last active: 8 days ago - Tests: 3

    I have over fifteen years experience in linux systems administration and development, having managed large environments composed of many thousands of systems. I believe I bring with me a valuable perspective on how to provide solutions for efficiently managing extremely large, and distributed environments without scaling headcount. Some of my accomplishments include having built site reliability/network operations centers from the ground up, from the development of the fault and performance management systems to the management of the staff. I have built up and administered large scale email infrastructures which would send and receive millions of emails daily. I have managed datacenter migration projects consisting of thousands of servers running live services. I have extensive experience in the online gaming industry, focusing on adminsitration, server engineering, and DevOps. I have even worked in a creative capacity as a writer and creative designer in the past, having co-created the MegaTokyo™ intellectual properties. Given the variety of roles I've had in my career, I consider myself a jack-of-all-trades. What I enjoy most is being able to provide value to the organizations that I am able to support, regardless of what role that places me in at the time.

    Software Engineer over here! Domain-driven design enthusiast with passion for structuring flexible OO design with PHP.

Expert in design patterns with over 4 years of professional experience. I'm developing enterprise web applications, file sharing systems, websites, web application frameworks, etc. Achieving high quality of code, good performance and reusable object-oriented software design is my primary goal when working. I don't underestimate documentation as my source code is always well documented, with end-user manuals when needed. In the last two years I've gained rich experience with Dependency Injection and Service Locators and successfully applied those approaches my projects. I'm always ready to learn new approaches, if they could make my work quicker and easier. I have experience in educating developers. I've been teaching students PHP, Zend Framework(basic and advanced levels), MySQL, jQuery, Design Patterns and etc. I'm seeking to develop big and complex web applications using the last technologies and software development methodologies.
