Do you need someone with awesome communication skills, a solid understanding of web design, and swell English? (Yep..."swell".) Are you a fellow entrepreneur/internet marketer who needs to customize your unique project in a way that matches your style and branding? If you answered "Yes" to any (or all) of the above, send me an interview request today. I always aim to exceed my clients' expectations, and a review of my client feedback will confirm this. I'm looking for interesting projects in the following areas (preferably in the real estate industry, but open to interesting alternatives): - light web design work/customization/consulting for real estate agents & brokers - lead generation / internet marketing consulting for real estate agents & brokers - automation consulting (I can help you get rid of time-consuming / redundant / redundant tasks so you can focus on more important things) Preferred Contracts: - $300 minimum (if flat rate) - Less than 5 hours per week (if hourly) Send an interview request today and let's see how I can make your project a smashing success! 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. GAME. CHANGER. If you've read it, you know what I mean. If you haven't: read it. Real Estate Experience: - licensed residential real estate agent since 2005 - full-time real estate agent 2005-2010 - worked with investors, relocation companies - former real estate Board member + teacher Web Design And Lead Generation: I have spent the past 9 years working extensively with: - Custom landing pages/"Squeeze Pages" (many for the Real Estate niche) - AWeber + GetResponse automated email delivery services - Loan Pre-Qualification forms (designed for real estate agents + residential lenders) - Tons of form-filling processes and data capture on the web - Wordpress integration, theme customization, and theme-building - Internet Video integration - PDF/eBook generation - Fixing bugs so sites display correctly (a necessary evil) Sales & Marketing: - I've been selling enthusiastically since the age of 5 (it started with selling pencils door-to-door. I made $2.50 in 15 minutes. My mom yelled at me and made me return the money. 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. Send me an interview request today and let's see how I can be an asset to your project! 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.

    Web developer

    Russia - Last active: 1 day ago - Tests: 12 - Portfolio: 12

    Lately my work is about integrating Bitcoin-related functionality in websites or developing special purpose apps, like a bitcoin trading bot or a websocket chat. It involved various technologies: node.js, websockets, Ruby, Sinatra framework, Blockchain.info API, PayPal API. During the years of my work prior to this I've performed a big variety of tasks in developing and reworking websites. This involved a lot of programming with PHP+MySQL, layout works with HTML+CSS, Javascript (with and without jQuery), AJAX. I had experience working with various CMSs: OpenCart, Joomla!, Wordpress, MODx Revolution, DataLife Engine, SimplaCMS, self-written websites. Also with different frameworks: MODx, Yii, also self-written MVC structures. I also use regular expressions (RegExp) fluently and have quite some experience with that. I've integrated a number of payment systems in several websites, which included PayPal, Bitcoin (native and via Blockchain.info API) and russian WebMoney, Yandex.Money, QIWI, Robokassa. All payment processors utilize mainly same principles, so it's no problem to learn and integrate something new quickly. My work included creation of web grabbers and parsers that process information from external websites, for example to fill up an online store database. Also setting up and administrating Linux/FreeBSD VPS servers: installation and configuration of Apache, PHP, MySQL, Python and some other uncommon software. Aside from pure web, I've developed Python and Ruby scripts for various services. A part of that was developing Bitcoin-related services, including API communication with bitcoind daemon, automated receiving/sending Bitcoin payments, trading on BTC exchanges via their API, and other stuff. I'm looking for interesting work opportunities that would let me develop my skills and acquire new ones. Cryptocurrencies are especially interesting to me, but if it's not the case, no problem. Most likely I can be useful to solve your programming issues, so feel free to contact me.

    United States - Last active: 4 days ago - Portfolio: 5

    Well before the World Wide Web was a common phrase as it is today, before most people even owned a home computer I was programming code in a variety of languages for a variety of network related projects back when you had to put the handset of a telephone on a 300 baud modem. Trillions of lines of code under my belt and a mind that functions like a computer processing unit I not only understand today's most popular programming languages, I know how the languages themselves came to be. I am an expert who has owned, operated or worked with thousands of technology based businesses over the past 25 years. More than a programmer, I am a valuable consultant to any business wishing to build or improve any online enterprise. My work is relatively fast, accurate, functional and most importantly well constructed based on your exact needs. I do all of my own work but will bring in experts if necessary to accomplish the goals of your organization. I am an American living in Pennsylvania.
