Mostly on site but sometimes from home or the hackersandfounders building. I can work in a team, with other frontend developers or with backend developers. Although I'm interested a lot in new web technologies, I appreciate the stable ones just as much.
I founded a small company, Checkmythesis, for proofreading academical papers. Learned a lot from it as well. Trade-offs between choosing the 'hottest' technologies and getting the job done. Using php for an e-commerce system instead of building your own solution in NodeJS. For a new project I am involved in, I'm using flask so we have an admin completed in under two weeks. The same principle applies.
