Software developer. I also do technical documentation and support. I actually use a different board depending on the main task of the day. A slightly stiffer Mammoth75 with JWK Koala for development and a tad lighter Q1 with Durock T1 for the days I have to do a lot of support or technical documentation.

When I need to work from the kitchen table because my wife has a meeting in our shared home office I use a Nuphy Air75 with lubed Gateron brown low profile switches.

My wife, also a developer, uses an Ikki68 Aurora with the aforementioned Boba switches (changed from the TKC Dragonfruit she was using before).

I started using mechanical boards to help fix my wrist pain. A lot of money and nearly a dozen boards later I think I have finally found my endgame.
