    Senior Javascript Developer

    United States - Last active: 1 month ago - Tests: 1 - Portfolio: 1

    Right now my main interest would be in building 2D games using Unity, but I'd be interested in other game development opportunities as well. I have a very solid work ethic, and am used to working 10-20 hours/week on side-projects in the evenings. My latest side-project, NetPegs, was recently released for Amazon Fire TV, Google Nexus Player, and PC/Mac. By day, I am a senior Javascript developer with many years of professional development experience, both in the browser, and on the server. I have experience starting new projects from scratch, and also converting existing software from server-side platforms over to single-page Javascript apps. Although I love doing Javascript development, I get enough of that at work. In my free time, I'm most interested in making games.

    5 yrs exp Full stack Software Developer on LAMP Stack, AWS Cloud.

    India - Last active: 5 days ago - Tests: 5 - Portfolio: 3

    I have 5 years experience in web software development using LAMP stack. Linux, Php and Mysql are my areas of expertise. I have good 3 years hands on experience on Amazon Web Services. My current main area of interest is software development using Php core / codeignitor framework and customizing a Amazon web services solution for hosting the application. I am comfortable and happy to create a state-of-art software solution using Php core and CodeIgnitor Framework, Mysql, HTML5, CSS3. I am a Oracle certified Professional Database administrator and Oracle certified Professional Applications database administrator (Oracle License ID: OC1134893), hence DB activities like db maintenance, indexing, statistics collection, backup, recovery and logging are few activities I comfortable with. Using GitHub / BitBucket for code revisioning, pivotal tracker / Zira for tracking the progress based on Agile methodolgy are tools which I prefer to increase efficiency and transparency of the progress made. WEB SOFTWARE DEVELOPMENT BACKGROUND: I have good hands-on experience and knowledge on Back-End (Linux, Apache, MySql and Php) and Front-End (HTML5, CSS3, object oriented Javascript) web technologies. I have single-handedly developed a Learning management system project on LAMP stack which is the only learning management to support multiple role based login (Teacher, Student, Parent and School). Had run the project for 2 Years with 4 release cycles. (See below in portfolio). I am a firm believer in open source technologies and am a contributor to Elgg development (Open Source Social networking platform). I use open source within my work wherever possible. Since I am new to Upwork freelancing, hence I am keeping myself open to work on a wide range of projects; from a simple Web-page creation to complex software building. WHY ME: I am a kind of person who if does not know an answer to a problem will tell you that I don't know the answer, but I will be the fastest to find the correct and the best answer to the problem. I am a problem solver. For me, technology is a tool of expression and thus I focus on understanding the problem and then curating the best possible solution for you.

    MEAN-stack Developer & System Administrator

    Sweden - Last active: 1 month ago - 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.
