My Background

I currently work as a Principal Engineer at TrustedHousesitters.com, overseeing the development of both the Mobile App and Web. My recent projects include iOS and Android Apps using React Native, web rewrite in ReactJS, Message queuing service, Search engine, and a Media management system. I am leading a team of engineers working on a variety of projects, giving mentorship and direction to my colleagues.

As a software engineer, I strive to write top notch and well working high availability software. I have a wide background in the software development process, covering design, coding, debugging, testing and maintenance. I have designed and implemented many adaptable solutions that support functionality changes.

When not coding, I can probably be found spending time outdoors, hiking, snowboarding, playing basketball or getting ready for a road trip adventure.
