    Brandon Miller

    Principal Software Engineer

    United States - Tests: 1

    I am a highly motivated individual with over 9+ years experience in Software Development and Test Engineering. I have leadership experience and excellent communication abilities. Education-wise, I graduated from one of the nations best ranked universities (San Diego State University) with a BSCS and completed MS CS degree course-work. I have the ability to pick-up new technologies fairly quickly -- I'm a technologist at heart. The bulk of my professional experience, however, has been in developing scale-able web-services (RPC/REST), building test automation and frameworks. No matter the project, there is nothing I cannot accomplish or figure out. I have experience building/testing solutions using the following languages: C++, Perl, Python, Java, and JavaScript. I've used a variety of frameworks, but not limited to Flask, Django, SQLAlchemy, Mojolicious, Spring, CXF, Jersey, Hibernate, etc. I'm familiar with most RDBMS such as MySQL, Postgres, and MSSQL. I've also used many key/value storage systems such as MongoDB and Redis. I also have DevOps experience setting up AWS infrastructure with Puppet/Saltstack to configure/provision machines. This will allow your infrastructure to scale and ensure things are not error prone with true Automation in place. I'm realistic, so we'll make sure we're both on page before beginning any project together and quality isn't a back-burner for me, so you won't get a half-working solution.
