My wife was diagnosed with Celiac 15 years ago and it has become A LOT easier to deal with now then it was back then. Nowadays it's pretty easy to get substitute ingredients to make most recipes GF.
I don't have a dedicated website for GF recipes but
https://www.skinnytaste.com/ is a good one since you can sort by GF options. Also any paleo websites work since that diet doesn't include wheat and bread.
I've found that instead of dedicated websites I just stick to individual recipes. If I find one we like I'll bookmark it or print it out and go back to it often.
Feel free to reach out if you have any more questions or input. I'd be happy to help
