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. Thoughts?
Continue to take free stanford/coursera courses. Maximize stock market investments. Look into starting your own tech or fintech company
