I am a driven, full stack software developer with over 3 years of professional experience. Software performance, security and user experience are my main driving forces, coupled with a desire to learn new technologies and tools. I have a very amicable personality and am always happy to help others, mentoring more junior team members. In my free time I like to contribute to the open source community on github and stackoverflow, keeping up to date on current technology.
