Web Developer - Proficient in PHP, Laravel, Javasc...

Portugal - Last active: 6 days ago - Tests: 4 - Portfolio: 3

I've worked closely with world-class companies throughout the development of outstanding platforms that have been used by thousands. I'm proficient with PHP and I'm also a Laravel early-adopter - I've been using it since early version 3. I've developed countless applications with Laravel, attended the Laracon conference in Amsterdam and I've written several tutorials that have helped hundreds of other developers. In addition to PHP, I've also used Ruby on Rails extensively to develop complex web applications with full featured test suites. Being a Software Engineering student, you'll be sure to get solutions that are well designed, easy to scale and develop upon. I've taken a CAE (Certificate in Advanced English) by the University of Cambridge and passed with flying colours. Communicating with me won't definitely be an issue. Looking forward to working with you on your next web app!

Linux sysadmin, cloud deployments specialist

Czech Republic - Last active: 1 day ago - Tests: 9 - Portfolio: 1

I would like to offer you my deep knowledge of servers hardware and software, which allows me to fine-tune servers according to their roles, and my ability to anticipate and solve problems in shortest time possible. No Windows please, Unices only, Linux preferrable. Lately my main point of interest has shifted to deploying and maintaining web projects in cloud environments. I am developing monitoring / management tool ( http://m-script.org ) and supporting existing installations, but I am very well familiar with all well known alternatives from both monitoring and cloud management side, so no problem to implement any of them. The point is, I know very well how it works. And how it doesn't, too :) I am interested in any system administration work, especially in cloud environments. The more challenging you setup is going to be, the better. Automated scalability, cross-clouds deployments, combination of traditional and dynamically scalable resources, DNS/Geo balancing - everything is possible, just let me know your needs.

Rails Dev With Diverse Skill Set

United States - Last active: 25 days ago - Tests: 5

Hey, what's up? Thank you for reviewing my profile, I'm glad you stopped by! My name is Dave and here's the skill set I can bring to your project or team: Ruby on Rails Development - Experience with Heroku, Postgres, Devise, Pundit, Paperclip, Geocoder, etc. Front End Development - Bootstrap, Sass, Less, and a little bit of AngularJS Graphic Development and Retouching - 11+ years of Photoshop experience with an extensive focus on photo retouching, complex compositing, and stylized post production. Other Cool Stuff - Audio engineering, video editing / post production, marketing, and I'm a damn fine party planner! But wait, there's more! I also speak fluent English, am on EST time, and according to the Dali Llama, on my death bed I'll achieve total consciousness, so I got that going for me. On a serious note, I am looking primarily for ongoing rails positions that will challenge me and expand my knowledge. I also know that being able to fill some gaps when needed can be a huge benefit. I am happy to jump in and be of help in a range of areas outside of web development if needed, such as marketing and content creation. Finally, and as I would expect from anyone in web development in this day and age, I am very familiar with Wordpress and able to assist with just about anything a project could require. I would love to chat with you more about your thing / project / hopes and dreams / and the like... So please hit me up with a message and let's do lunch. Thanks again and talk soon!
