Re 1—It has been a bit of annoyance growing up (for example, Google autocorrects "Alexandr Wang" to "Alexander Wang"), but we run different circles ;)

Re 2—As with most companies working on ML these days, our stack is not fully proprietary. We don't take too strong an opinion on ML framework and use both Tensorflow and Pytorch currently. We generally use neural network architectures from the literature and then iterate on top of them to suit our unique problem requirements.
