Hi do anyone has a formula or tips on working on two different freelance software projects at the same time?
Ps: both has same project time frame (1 month), different programming tools: ( Ruby on Rails), the other MERN stack...

Buy two screens, one for each eye

Don't.

Fix a time for each. Based on the amount of work required.
And based on frequency of reviews for the projects,
You can do alternate days, proj1 for one day and proj2 the next. Repeat.
Or alternate 2 days each.
The longer the better. Because momentum.

I’m doing several at once too. It’s overwhelming sometimes. But discipline of fixing times for each is the key to getting them done without losing time and sanity
