    Poland - Last active: 14 days ago - Tests: 16 - Portfolio: 18

    I have worked as a PHP developer for about 7 years for now. My experience in working on a wide range of projects allowed me to work with large corporations like Adidas, Reebook and Unilever - that kind of clients are very demanding and expect performance to the highest level. Thanks to that cooperation I know how necessary thing is good communication. I worked in a team of developers as well as on my own, additionally, I have experience as a team leader. Worked on small projects and some bigger ones that took over a year to complete. I am very much familiar with the latest technologies such as: PHP 5x (OOP), MySQL 5x/Postgresql 8+ (usually with ORM if needed), MVC Frameworks, jQuery, Mootools, DHTML, CSS3, HTML5, Youtube/Facebook/Twitter API to integrate projects with social media. All my applications are SEO optimized to play good with google and easy to work with SEO companies.

    Netherlands - Last active: 2 days 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.

    Canada - Last active: 2 days ago - Tests: 8 - Portfolio: 65

    I have over 11 years of experience in website design + development, and User Experience Design. I also own a Wordpress design and development company located at http://www.wp-dd.com (acronym for Wordpress Design and Development). My core competency and focus right now resides in Wordpress design and development as Wordpress it is one of the best content management systems available. I use the CMS for clients and businesses, especially for those who are just starting to get online. For a full portfolio please visit http://www.wp-dd.com I create great designs and ensure that all my clients are kept updated and well informed during the process of design + development. If this is your first website then you will receive great support from me in terms of getting you on your feet and managing your Wordpress site effectively. Please contact me if you have any inquiries and/or if you wish to get started right away! :-) JOBS IN PROGRESS ------------------------------------------------------------------------------------------------------- I've been getting a lot of questions regarding the large number of jobs that appear to be in progress on my profile. Note however that not all of these contracts are active, they are either: 1) Contracts with clients that have gone m.i.a. 2) Contracts that are on-demand i.e. work when required for the same client. 3) Actual active contracts, these are roughly 10 or so at any one time. PAYMENT AND MONEY BACK GUARANTEE ------------------------------------------------------------------------------------------------------- On fixed price projects I normally request 33% as an upfront payment. This is followed by another 33% after majority of the site or the work required is completed (about two thirds of it) and ready. Remaining 34% would be due upon successful launch/completion/contract closing. Sorry but I do not take on any work without a minimum of a 33% deposit. MONEY BACK GUARANTEE ------------------------------------------------------------------------------------------------------- If you are not completely satisfied with the work that I do then I will refund the fee paid, including the initial 33% upfront deposit. There must be a specific reason for finding the work unsatisfactory e.g. not meeting set out requirements, multiple missed deadlines, however a reason like not needing the project done anymore would not enable a money back guarantee. SETTING UP AN UPFRONT PAYMENT ------------------------------------------------------------------------------------------------------- Due to a change in oDesk policy, upfront payments are no longer as easy to setup as they used to be. A client would first have to create a milestone with the amount of the upfront payment, I would have to submit a request for payment, and the client would have to approve it. FEEDBACK AND TESTIMONIALS ------------------------------------------------------------------------------------------------------- Aaron is an excellent WordPress developer. He went the extra mile on the project and handled some unexpected issues with skill and professionalism. I would definitely hire Aaron again- Jtices Valuable addition to my team!; - Emini Academy "Aaron is a phenomenally talented wordpress web designer. The scope of this project was complex, challenging and something we were just crossing our fingers that maybe, we will get something close to what we wanted. To say the project was completed successfully is an understatement! Aaron absolutely blew the roof off this one and delivered more than what we bargained for. We now have a website that everyone is proud to be associated with, matching the best of the best websites out there. Aaron - you rock!" - oDyPortal Aaron was great. He put a Wordpress site together in no time and added a lot of important features which I was not even aware of. It would be great to work with him again. + more available on my oDesk profile below.
