I started working with Vue since the early versions of the framework. I have used it for most of my Front-End projects for the past few years. I'm a proficient Front-End developer and love creating beautiful interfaces and experiences. Attention to detail is a huge deal for me, so I'm also an empirical designer. I've done work both on Back-End and DevOps/Infrastructure, as I've had to deal with end-to-end / Fullstack developments in 2 startups I cofounded, but my most developed ability I think is in Front-End development.

I've been coding in PHP, although intermitently, for more than 10 years and have used several frameworks, as well as designed small frameworks or toolkits for own use. Sadly they're not available as open source projects, but I've had the experience of building full-fledged PHP sites, or PHP backends with my own design for routers, serializers, models, etc., both on top of existing frameworks, or from scratch.

I've been a web developer for more than a decade, which means I've dealt with several languages (PHP, Ruby, NodeJS) and their frameworks, as well as deployment tools / environments such as Heroku, Docker, Apache, Nginx, etc. Also different databases such as MySQL, PostgreSQL, RethinkDB, etc.

I've been doing work on Front End, involving different frameworks and languages for more than 5 years. I love CSS challenges and creating usable UIs, that's why I also developed my own small CSS library called Funcssion (funcssion.com) which is inspired by the philosophy behind pure functions (no side-effects), and I use it nowadays for almost every project or prototype I want to build.

Product was an Instacart for Colombia and Mexico (this one for a short period). I lead a small development team (3 people) and developed most of the startup's software: Hybrid mobile App (using Appgyver Suppersonic + Codrova Phonegap), a Ruby on Rails API and a PHP administration system on the back end, a Ruby on Rails + Angular Front End and the setup of the entire infrastructure, mostly in Amazon Web Services (AWS) and Digital Ocean, using Dokku (a Heroku-like tool based on Docker)

funcssion is a set of really simple CSS classes, with a single purpose, inspired by the philosophy behind pure functions. This basically means, they attempt to avoid side-effects. It's not a full-fledged CSS framework, but rather a very handy set of classes that'll help you prototype really fast and understand what your components look like just by looking at your HTML code, not browsing through endless, repetitive CSS files and classes.
