Another continental European here (also software developer). I know most non-native speakers will never learn "proper" English pronunciation (whether AE or BE or Australian English I don't care) and international English is here to stay but, man, the many ways in people butcher English pronunciation (not because they pronounce everything as in their mother tongue – that's fine – but because they actually try to put on a native AE or BE accent) still makes my ears bleed on a daily basis.
