How to fix concrete so when it rains it doesn't puddle?

We have a walkway that is bordered by our house on one side, and a concrete wall on another. The walkway is made of concrete and over time it has settled and has become uneven. When it rains, puddles form in those areas even though we have a bit of a slope in the walkway that goes to a drain. What is the best way to fix the uneven areas?

The simplest, least time-consuming repair would be to spread a concrete patching compound over the area. You want a bagged mix that can be troweled to a feather edge. Following the instructions on the package, clean the walkway, stir the recommended liquid into the compound, and pour it in place. Then run a straightedge over it to level it with the surrounding surface.
Use Decking squares to provide a dry walkway over the top...
Won't water still settle under them and erode the squares? I like the idea and perhaps the look!
Use a latex modified self leveling concrete resurfacing compound.

Yes it's used in leveling garage floors
Yes, a concrete leveling compound. Definitely the dirt residue in the puddled areas must be power washed out of there.
And you might even etch it clean with muriatic acid solution or some other etching cleaner. Use appropriate PPE when working with all chemicals.
It won’t last very long if the surface is not super clean.
