  • A Year Building a WebRTC Application: Lessons in Startup Engineering (Publication)
    I've been an Engineer at Toptal for just about one year now, working on the same project since I joined the network: Ondello, a service that connects doctors and patients over WebRTC. When I first joined Ondello, I was hired as a Senior Ruby on Rails Developer, tasked to build a service up from scratch. These days, we're a team of multiple developers working on a fairly large, complex system. With this post, I'd like to share the story behind Ondello. Specifically, I'd like to talk about: how a simple application became not-so-simple, and how our use of cutting-edge technologies posed problems I'd never considered before.
