In particular I've found that if you have a good infrastructure layer available on which you can deploy then it's much easier to throw small purpose built webtools on there that solves personal problems. Infra here being fixed IP, mTLS reverse proxy, k3s/container, S3 etc. Basic building blocks like that - store data, run app & safe gateway to access it.

If you have that in place then most smaller apps (shopping list, notes etc) is a couple prompts away
