Courses/Certificates for Mid-Career Advancement?
As a senior developer with 15 years of dev experience, what would do the most for career advancement? I enjoy development, but I also want to do big picture stuff that has enough value to earn more than just a senior dev / architect salary.
Should I just work on a Master's degree in CS and specialize in something complex?
Should I get an MBA and transition into a management / business role with a heavy hands-on tech background?
Should I take free/cheap Coursera courses in valuable skills like ML or data analytics and transition to a higher paying dev role?
I love what I do now (front-end development), but I don't see a path to a significantly higher salary band as a front-end developer.
