I really like this for technical roles. Or tech companies in general. That said, they don't have any job descriptions or requirements beyond the API request so it's not easy to tell what they're looking for or how qualified you are. Plus there's no posted salary range
"blockchain" tends to be rather iffy too, especially since it's seemingly inevitably tied with cryptocurrency or something like it in some form or another.
Hey, I'm a senior developer with 25+ years' experience and more languages and tools and stacks and environments and so on that is reasonable to list in a comment. In my decades of experience, finding someone who is legitimately good at Excel is a rarity.
Cuz you either graduate to real programming and databases, or languish in some kind of hell where you work in excel all day and have to get good at it to save your sanity
