Decking over a tile / concrete slab

First time poster and not a builder. Just wondering if the below is possible:I want to deck over our front porch (~1m x 4m). The porch is currently tiled over a concrete slab. I was thinking of laying joists over the top and then decking on top of that; however, I was wondering if you can lay joists down so they aren’t as tall? I understand that this will make the deck less stable in a normal circumstance, but will this be the same as the concrete slab is already there? If I have the joists standing upright then it will be too tall for our entry way. Thoughts?

My deck-over is trex and is virtually totally maintenance free - and not as slippery or "hard" as concrete, or worse yet - tile.

The roof is an advantage but moisture still plays a role.

The bracket will work providing it keeps the wood off the concrete. Something like this is the idea...

You can get 1 1/2" trex at a real lumber yard.
