In an afternoon, i built a core prototype of an airline schedule compare app in TornadoFX. I've been hired partially to replace VBA-riddled Excel workbooks with small TornadoFX business tool apps. The effort and amount of code is much less, and surprisingly I am getting a lot of buy-in from my coworkers and leaders. Just need to teach them how to do it and mitigate supportability risks, which is dismal with VBA anyway.
