    Web Development Expert with System Designing & Frontend Skills

    India - Last active: 2 months ago - Tests: 5 - Portfolio: 12

    Couple reasons why hire me: - Unlike other great developers I know how important is to keep an communication channel. - My working hours are very flexible. I can work for your timezone and I can be available with couple hours notice (depends on communication channel). - I've started developing web applications 8 years ago. By now I was exposed to different areas of product development aspects (not only just coding), so when you need not only coder, but also someone that thinks logically/analytically, I'm your the guy you need for application. - Completed all my odesk job with 5 star rating with excellent client feedback and 100% client return ratio. - Even though my rate may seem little high I can assure you that I'm efficient and spending time purely on planning and development. I'm never charging for anything not directly connected with project (for example filling the knowledge gaps; there will be always something to learn). In the end you're not just getting a efficient developer (peace of mind), but also someone that will help you with project in general (excluding graphic design; I just know I'm not good in that area). Over the last 8 years I have developed many web applications using HTML, CSS, Ajax, JQuery and Server side programming language like PHP & storage system of MySQL for startups and other companies. I also work on latest technologies of HTML5, CSS3 & Bootstrap. I also have wide experience working on CMS like Wordpress, Joomla, Drupal & Ecommerce platforms like Magento. Looking forward for your chance to work with me.

I've been designing websites, graphics, spreadsheets and software for over 17 years, over 95% from scratch. My specialty is the area having to do with "Direct Response" methods of lead generation, having studied almost every Dan Kennedy book and dozens of self-study courses over the years. I eat, breathe, sleep and dream sales and marketing. You think like an entrepreneur, and so do I...because that's almost all I've known for over a decade. I've been self-employed in some form my entire adult life. Borderline-obsessive work ethic is just another day at the office. I've gone through Tim Ferriss' "4-Hour Work Week" almost a dozen times.

It was on this day that my disdain for authority was born...) - I own (and actually completed) more sales, marketing, real estate investing, and real estate agent training courses than I can count (over 100 at least) - I hired a professional sales and marketing coach for approximately two years while practicing real estate, and amassed a well-rounded business education along the way - Barely old enough to vote, I spent 3 years selling telecommunications service and building sales teams I've also spent more time than I can count on: - Writing custom email campaigns - Writing eBooks and Free Reports for website give-aways - Designing custom graphics, flyers, and advertisements - Designing website elements (logos, buttons, banner graphics, backgrounds, etc) - Copy writing / sales letters (long- and short-form) Long story short: I have a strong background in the many aspects of internet-based sales and marketing, I love sales and marketing, and I'm a stickler for details.

I'm very familiar with the following languages and tools (if your project requires them): - HTML / PHP / CSS - Javascript / jQuery / jQuery Mobile / AJAX - Adobe Photoshop / PSD-to-HTML - MySQL databases (and website integration) - Microsoft Excel (I've designed hundreds of custom spreadsheets and 3 complete software solutions for myself and clients) If you're looking for a developer or content writer with a strong background in the finer points of sales and marketing, one with an obsession over the details, one with a thorough understanding of what it takes to generate you more business and get you more email subscribers, send me an interview request today and let's see if we're a match.
