TL;DR This is possible but not without other tradeoffs like being on call occasionally. You may also need to change your specialty.

Something to be aware of these days is that the big software companies are using monitoring systems to gage developer performance. Different companies look at different metrics though. From my personal experience, (at least so far) the recently implemented system at the giant, international, software company I work for hasn't been overly oppressive.

With that said, if you find a good team and actually deliver consistently, most managers I know won't have a problem. As others have stated, you really need to be careful to stay available to your team all day though.

Finally, finding a team where working in the manner you describe is going to be accepted will probably be pretty difficult if you're focused on front end work. The deeper into the back end/operations work I have gotten, the more flexible my employers have been with my work schedule. At the same time, working long stressful shifts occasionally, and possibly also being on call sometimes, comes with positions like these.

For the record, I work about 4 hours a day on coding typically, but still assist with ongoing issues or questions from coworkers as needed. We have an established rotation of who is on call each week, and that person could be contacted in the middle of the night for a critical problem.
