AI engineer at Madrid City Council, building MarkEdit on the side

Hi everyone!

I'm David. I work at the Madrid City Council as part of the Artificial Intelligence team, where I build AI tools and systems. In my free time, I keep that same building habit going on side projects of my own.

Lately that's turned into MarkEdit, an iOS app I'm building because I genuinely couldn't find what I wanted: a Markdown editor that combines writing with Mermaid diagram editing in a WYSIWYG style. Most editors either ignore Mermaid completely or kick you out to a browser to render it. I wanted both in one native, seamless place — so I'm building it.

I'm here to learn from this community, get honest feedback, and connect with other people who build things on the side.

Happy to be here!
