    End-to-end web developer specialised in Javascript, HTML5, UX/UI, Node

    Netherlands - Last active: 1 day ago - Tests: 2 - Portfolio: 4

    I love making apps, like my latest project: Rallypoint, sort of like Stack Overflow for private teams, with a focus on quickly moving on and not wasting time. www.getrallypoint.com I can get passionate about perfecting a front-end flow and layout with HTML / CSS and Javascript, designing entire back end systems using Node.js / MongoDB or the good old PHP / MySQL and turning raw ideas into reality. I'm goal oriented and have no trouble constantly zooming in and out. I think about the product from end to end, from owner to user. Entrepreneurship is in my blood. Ever since I was just a teenager I worked on getting better at web development. I'm always looking for ways to challenge and improve myself. Over the years I've gotten heaps of experience in: * HTML / CSS / LESS / SASS * Javascript, both front and backend (React, Node, Flux, Backbone, Angular, Hapi, Express etc.) * PHP * MySQL / NoSQL database design * MVC Frameworks (Laravel, CodeIgniter, FuelPHP, etc.) Ofcourse I'm proficient in any tools that I need to do my job properly. I use Slack, Skype, Email and Google Hangouts to communicate, Sketch and Photoshop to work convert designs from mockup to HTML, Trello / Basecamp / Highrise for project and client management. I've got a smartphone and tablet and am hardly ever disconnected.
