Focus on a niche and specialize more than “software”. As a junior you have some time to figure it out (but don’t take too long). Software is everything these days, so if you can focus on a subfield you’ll maximize your future earning potential and lifestyle. It’ll also help you stay technical well into your career.

To do this, keep your eyes open for opportunities to go deep into something interesting at your job and be the company expert on that topic. This is a nugget of a personal brand. Then take this and expand on it outside your first job. Blog about it. Speak about it. Create open source about it. Find the next job that hires you for these specialized skills. Rinse repeat...

Worst case is you can still switch, or go back to just “software developer”
