I like to consider myself a professional software developer. I spend a lot of time in front of a screen. Because of that I think it’s completely worthwhile to spend a fair amount of money on having a high quality ergonomic workspace. Monitors go on adjustable arms. A standing desk means the desk is always at the correct height, no matter if I’m standing or sitting. A high quality mechanical keyboard and trackpad mean minimizing the chance of RSI.
If your company pays for that equipment, great. If they don’t, buy the right equipment anyway. Spending a few thousand dollars is far cheaper than spending many thousands of dollars in medical expenses. It’s a small investment to make sure you can be a happy and healthy developer well into your career.
