Pretty old school in some stuff (I used to own at Logo with Poly 5 with colors and making some races with them, while my old brother was ruling with Frogger, Choplifter and Dig-dug at our Atari 130XE) and newbie in others. I work (or used to in some cases) with jQuery, ReactJS 15/16/17 (FLUX, Redux, Hooks), Symfony 2-3, OpenLayers 2-3, ArcGIS JS-API 3, PostGIS, Laravel 5.1, 5.4, 5.5, 5.6, 5.8, Angular 6-7, AngularJS, NodeJS, Express, UIKit 2, Bootstrap 2,3,4, Material-UI, React Native, Lerna, Serverless framework, AWS (Cognito, DynamoDB, Lambdas, API Gateway, etc), Github Actions, CircleCI, now I'm struggling to work with MongoDB, Drone, Sonarqube. I also know a lot of nutrition (the sumo pic is not me by the way). Actually, I think I know more of nutrition than anything that I post or ask here at StackOverflow.
