I actually work at a software/services company for commerce. Don't get me wrong, this is a big space and there are many challenges but they often tend to be more vertical than technical. Lately I've been making a monolithic app behave less so with decoupled async notifications. Also spend some time prototyping things for future adoption for if/when that's feasible. I'd like to be using something functional like F# but for some reason not being in adtech/fintech drastically lowers tech appetite of companies.
