If you have a personal project in Arduino that you really like, I'd suggest trying to get that running on a bare metal dev environment, As opposed to trying with a brand-new project. In a previous job, we used Arduino (environment+boards) to quickly spin up prototypes and testing new peripherals, then moved them over to bare metal (avr-gcc+Makefiles, custom PCB) for our production. And if it's not too demanding a project, give this a go with AVR first, it's much simpler to move to bare metal than with ARM. Feel free to email with any questions.
