StackTrek allows learners in paid courses to get affordable one-on-one programming help at the moment that they need it. StackTrek connects a network of top local/regional developers, so learners can visit the site at any time, describe the problem that they're facing, and then in real-time get connected to an expert developer who can review their code, talk them through the issue via live texting, and work on the code together in a collaborative coding environment.
