Use a journaling app, and write a few notes on what you did everyday. Each week, write a summary, grouped by topic: on project A, did 3 MRs, assisted pre-sales team on product X... At the end of the quarter, review the weekly summaries. Done.

I've been doing a version of this for the past 14+ years. Every manager I've had always told me I have the most detailed yearly review. It's been invaluable to me, as my work has usually been very fragmented on different topics / activities.
