Portrait of Leonardo Soledade Costa

I’m a product and software consultant who writes code. I build and review web and mobile applications from database to deploy, and I like owning the whole project, not just one slice of it.

Before code, I worked in marketing: I was a media analyst at Meta and a digital marketing director, so I understand the business behind every feature. In my consulting work at Soledade, I bring engineering, product and growth together to take applications from validated idea to reliable operation.
