About me

I develop a full-stack framework based on ReactJS and NodeJS for building model-driven web applications on relational databases. It’s an open-source project (https://github.com/chilibase/chilibase) I use for internal apps like Grosh and Depaul, and I prefer delivering projects using this framework.
