I am a frontend developer and author based in the UK, specializing in JavaScript development and application architecture. I founded Newtriks Ltd. and have been remotely contracting for the last 10 years for global corporations and venture-backed start-ups. I regularly consult Angular, Backbone, and React, and train programmers in test-driven development. I'm an enthusiastic open source contributor and am the cofounder and lead developer of the live webcasting platform Sayansho Ltd. Please contact me to discuss your specific business requirements.
