  7. Tom Jordell

    Tom Jordell

    MEAN-stack Developer & System Administrator

    Sweden - Tests: 2

    I'm a full-fledged Web Developer and System Administrator. I am currently a full-time employee as a Lead Developer and the primary System Administrator, currently managing a large scale server cluster spread across the globe with load balancing and sharding of databases. I'm very passionate about development and servers in general and there's nothing else that fuels my drive like this does. I am completely self-taught which only shows the passion I have for development and servers and I enjoy learning new things. I spend a lot of my free time developing but I also enjoy spending time with my family and friends and often find ourselves riding motocross in the wild which is another passion of mine. I believe the web is the future, everything will be ported to it. There will be no programs or apps for either desktop or mobile devices, it'll all be residing on the web and I believe it is very important we make sure that it is in good hands when we get there. Decentralizing the web with something similar to the BitTorrent protocol is what I think would be a good option. I primarily develop in Javascript, utilizing NodeJS for back-end and AngularJS for front-end, always maximizing performance and quality by bringing as much of the back-end work to the front-end which decreases server load drastically. I've also developed in PHP and been working in frameworks such as Laravel. I always write object-oriented code. I've specialized on load balancing and clustering of applications to bring the best performance possible to the user. My workflow utilizes many third-party tools to ensure I keep an organized development environment and to aid me in development and keep me up to speed. I use multiple Vagrant virtual machines to bring me a good development environment and virtualize a production environment before deploying. I use Git for version-control and have a private GitLab setup on my servers, but I enjoy using GitHub as well. I use Yeoman for project scaffolding and Grunt to minify CSS, Javascript and renaming assets to force a browser cache reload. Grunt also gives me live browser reload so I save a couple of seconds each time I update a part of my code. The applications I develop can be deployed to Heroku or any other server with a single command. All my applications are responsive and delivers maximized performance while maintaining a high security level. I've worked with tons of API's and written a couple RESTful API's myself. These include Facebook SDK, Instagram API, Twilio API, DigitalOcean API, Mailgun API and many many more.
