I ran the software dept for a small consulting company and yes you'd probably never get a call back from me if you were applying purely as a developer. While we have hired late 30-somethings developers, it's usually because they offer some fairly unique tech skillset (i.e., a few years of production-quality FPGA experience, not a couple months dorking around with "whatever hot new technology" on github--that's something I look for in a fresh-grad). So I think for a purely tech role, beyond getting another job at a similar company doing similar tech, you're a long shot at best.
But beyond that, the one thing that would case me to look at your resume is if you were wanting a leadership position and had the corresponding soft skills and experience. It sounds like you do, so highlight that, and work on it. The advantage there is that management skills: talking to stakeholders, setting expectations and timeframes, finalizing deliverables...are all applicable no matter what the underlying technology. So there's no reason you'd have to limit yourself to ASP management roles.
My previous company had lots of young developers doing engineering with lots of new technologies, but they'd have never delivered a thing had they not been guided by some experienced devs who actually spent most of their time in Excel (or trello or Jira or whatever we happened to be using to manage the particular project).
