    For starters, I’m Clay Lua, a team lead with 8 years of web development experiences, who is currently staying in Kuala Lumpur, Malaysia. I am a graduate from Monash University and I have previously worked for B2Be (Australia based) and Experian Cheetahmail (a Fortune 500 company) who deals with a few million emails daily. I was voted best employee of the year 2008 and receive Best Performance Award for Cheetahmail v1.6 release at Experian (Malaysia) at both companies that i worked for. I also worked for Hewlett-Packard (Malaysia) as a senior ui developer before I became a full time freelancer on oDesk and was notify as one of the top 1% successful freelancer on oDesk. I have in my current repertoire, 8 years of professional web development experience and knowledge including a technical website (http://hungred.com) where I store all my knowledge findings online for sharing. Many of the articles were listed on Google's first page. I am highly skilled with Yii framework, advanced PHP, OOP, MVC, jQuery, advanced JavaScript, git, subversion, vim, CSS, HTML, LAMP, perl, Wordpress, node.js, express.js, sails.js, backbone.js, marionette.js, bootstrap, Amazon web services, deploy.io, mongolab, aws and ocean digital services,web purify, segment.io, filepicker.io, sendgrid, zencoder, agile development and deal with many different interesting scenarios such as big data, high traffic sites, weird performance issues and etc. In terms of seeing whether we will be a fit, here are a few things I look for in a project / client: - excellent team players who are responsive and strive for an objective or a goal in mind - being an individual contractor, I do prefer to work on projects that clearly contribute a business value to the organization they support rather than pet projects or random experiments. I only work on an hourly basis and guarantee to bring you and your team the best experience that you've ever worked with :) P.S: all times are tracked using oDesk time tracker Feel free to contact me with any questions. Good luck on your project!  less
