Yep. I had ABVD chemo just over 11 years ago, followed by (exceedingly rare) bleomycin lung toxicity that nearly killed me. First off, don't shirk the Chemo. It works (I had hodgkins lymphoma, in case you have the same), and the cure rate is very good. I wouldn't hesitate to do it again if I relapsed. Next; yes, chemo-brain is a thing, and you'll be a bit slower for the duration of the chemo. It was especially noticeable when trying to keep multiple ideas in my head at the same time. Navigating more complex codebases was definitely a challenge. It'll also take some time afterwards to get back to normal. I felt like I was back to "normal" about a year afterwards, but was at 90%-ish about 3 months after I finished chemo. The closest thing I can compare it to is a medium grade concussion (having had a mild-medium concussion while mountain biking). It is a slower recovery than a broken bone, but you do recover. In the years since, I've been lead architect, and head of engineering for various cloud infrastructure software projects. It definitely hasn't held me back in any way I can identify.
