I've been in similar positions but one note: do you really work 100% on proprietary software? If you've used any open source projects you can demonstrate skill solely through high quality bug reports for the tools you use, even if your main code is closed. I've certainly seen people participating in e.g. Linux, Python, Apache, etc. threads which made it clear they were solid developers.
