Casper da Costa-Luis

casperdcl
London, UK

I've been developing fully open source software (FOSS) for years. The estimated value of my ongoing unpaid work is ~$2,000/month. For example, I single-handedly maintain @tqdm, with packages downloaded nearly a billion times per MONTH. If you program in Python you've probably used them. I also summarise interesting articles at tldr.cdcl.ml on your request (far superior to LLMs), and definitely do not blog at gist.cdcl.ml.

See my profile casperdcl-badge for much more!

If that's not enough motivation: if you sponsor me for $1/month, I will set aside $5/month1 to sponsor others. Yes, your appreciation will be magnified fivefold.

Reaching this goal will mean that around 0.05% of people who starred my work also pay for it. I will also be spending $75/month sponsoring others.
