02 / THE PERSON BEHIND THE PIXELS
Small studio.
Deep curiosity.
Sascha Losko Independent developer
I make tools that bring the obscure into focus.
I’m Sascha, the developer behind Obscure Essentials®. I build native software for Mac and iPad, with a particular interest in chemistry, the details hidden inside our files, and the little things that make a workflow feel right.
AtomLens began with a simple wish: chemistry files should feel as at home on a Mac as a photograph or a PDF. That curiosity is still what moves it forward.
