I am a software developer at DRW Trading. I have a passion for discovering and maturing innovative solutions. My most recent work has been in the Domain Specific Language space where I've delivered applications that empowered subject matter experts to write the business rules of the applications. I am also very interested in maturing software design through developer testing and software testing in general.
