    United States - Tests: 6 - Portfolio: 13

    **** Please DO NOT contact me if you are unable to allocate a reasonable budget for your project. Note that I am U.S based, and I have been working in the web industry for over a decade. I am posting this due to the countless inquiries I receive daily with insulting budgets and "bids" (ie. - $400 for a custom logic web app that would require over 100 hours of development). Should you require an estimate, please feel free to inquire and I can provide you with a reasonable quote, including both cost and hours broken down. Thank you for your understanding in the matter. ***** Hi, my name is Eric and I'm a Sr. project manager with roots in PHP development, as well as an entrepreneur with over a decade of expertise in the web & mobile development sector. I have extensive experience in working with mid to enterprise level companies on custom app development & corporate site projects, as well as management of large-scale web projects that require a team of expert creatives & developers. I've had the privilege of working with various established tech companies & startups over the years such as Accenture, Junk My Car, & Google. Through these positions, I've learned what it takes to create, deploy, and maintain intuitive, aesthetically pleasing web applications utilizing the latest web technologies. My passions within the industry are user interface (UI) design, custom PHP development, and enterprise level eCommerce builds. I also have an eye for the latest internet trends, while still being able to maintain a sense of originality in all projects that I lead. A few of the many web/IT skills that I specialize in are custom PHP MVC framework development (Codeigniter, Yii), MySQL database design/management, custom CMS driven web development (Wordpress, Expression Engine), Salesforce management/customization (including APEX development & advanced reporting), Unix & MS server deployment/administration, strategic UX & A/B testing, IP telephony (including Twilio API development; CTI/PBX), and enterprise eCommerce development (custom Magento development, including eBay integration). HTML5, CSS3, and jQuery are commonplace in all responsive front end projects that I've been a part of. Search engine optimization (SEO) is also a major skillset that I implement on a daily basis (both organic & PPC), and I'm an expert in utilizing/integrating SEOMoz & Hubspot. I've been creating & managing client Google AdWord campaigns for over 7 years now, and I am also an authorized Google Partner, as well as a Google Engage agency partner. My abilities in communication and project management are quite extensive, and I'm an advocate of implementing agile/SCRUM methodology & software. I'm familiar with efficiently utilizing kanban & burndown charts to increase productivity within development projects, especially when used in Pivotal Tracker or Jira. Much of my management skills have been acquired from running a successful development firm for over 5 years. Above are just a portion of the skills that I've acquired & mastered throughout my endeavors in the web industry. As this industry is ever-changing & evolving, I constantly strive to learn new web technologies whenever possible. I appreciate taking time out of your day to read through my profile, and I encourage you to view my portfolio on here as well. Should you have any inquiries or potential projects that you'd like to discuss, feel free to contact me with further details and I will get back to you as soon as possible. Thanks again, and I look forward to hearing from you! Eric K. Atlanta, GA
