I would also recommend checking out this company *URL removed by moderator* and look through the portfolio and cases they have. It's quite a lot, the experience in the field is huge.
*Moderator edit: I looked through every case study reported on this company's web site, and not a single one of the 10+ cases reported use of Qt. Plenty of Swift, ReactJS, NodeJS, HTML, PHP and others in their tech stacks, but no Qt. Therefore I consider this a spam post and I have removed the URL.
@shawnbaker830: If you can provide a link to a case on the company's public website that shows use of Qt, I will reinstate the link.
