I'm glad you're here!

Howdy! My name is Leonardo Losoviz, I'm an award winning freelance developer and consultant, creator of the open source PoP project (for building applications based on server-side components), regular contributor to Smashing Magazine, and occasional conference speaker.

I code, I learn, I share.


I am available for hiring! I specialize in building APIs (I authored an improved version of GraphQL on PHP, which is faster and offers more capabilities than the standard GraphQL), creating sites that run with any CMS or PHP framework and can be deployed on serverless PHP (I authored a component model which is the optimal mechanism to deploy atomic functionality, and which can work with WordPress, Laravel, Symfony and others), and optimizing content management across platforms (I authored a WordPress plugin to tackle this problem).


Happy reading!
