I had a 5 years gap in my career - all medical. Recently, right after that gap, I was intervieweing with multiple companies - most of them didn't even ask me, even though I was worried as hell. In the end I got almost all job offers I wanted. The only notable exception that didn't even grant me a phone screen was Amazon, their recruiter told me that ML has advanced so much in those 5 years that all my prior experience is totally irrelevant to them anymore. Oh, really. Whatever. In the end I ended up joining Facebook.
So with your 12 months gap and your prior experience, I would say nothing to worry about.
