    Creative Copywriter and Blogger

    United States - Last active: 15 hours ago - Tests: 7 - Portfolio: 7

    Employers- invitations to interview welcome! I'm a certified ELA teacher in the state of New York. I gave up the glamorous life of a teacher at a relatively early age because I much prefer working in my pajamas in the comfort of my own home office. My casual attire, however, is the total extent of my unprofessionalism. My primary goal is to write fresh, clean copy that meets your standards exactly. I am primarily a copywriter. I write: web copy, marketing/ promotional materials, sales letters, white papers, technical articles, press releases, as well as parenting and health/fitness articles. I also do transcriptions, editing and proofreading. I am currently on staff as a writer for DynAMC Magazine. I have acted as the parenting columnist for Edible Buffalo Magazine, have written feature articles for Evergeek Media, am a former blogger at the popular writing website, Scribophile.com, and have lent my copywriting services to companies like: Travelocity, HRD Press, MorePro Marketing, and Travel Babees. I've completed over 50 hours of transcription work. I'm a fast worker, a studied grammarian, an experienced researcher, and am internet/ SEO savvy. I am accessible, flexible and ready to meet your writing, researching, or editing needs. I'm based in Rochester, NY. Feel free to visit my website at: writerhollyjennings.com. Thanks for stopping by, and come back soon.

    End-to-end web developer specialised in Javascript, HTML5, UX/UI, Node

    Netherlands - Last active: 15 hours 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.

    Graphic & Web Designer.

    United States - Last active: 4 days ago - Tests: 3

    Some designers only work with restaurants, some with nightclubs, and others prefer more corporate design projects. I do it all. One week I’m designing marketing materials for concerts and restaurants, the next week I am working as a UI/UX designer for eCommerce companies spanning the globe. The challenges presented when taking on new clients allows me to expand my comfort zone, and push myself to become the best designer possible. My goal is to be the best designer on this website, and after being here a short time I feel I am well on my way. I am proud to carry a Five-Star rating here, and the only way I can maintain it is to take the projects I know myself to be the best fit for. I have never missed a deadline, on oDesk or in the corporate world, and I don't plan on starting soon. I have put years of work into building my reputation, and proud to be known as a person that simply gets it done. Have a project that requires great design that also needs to functionally serve your businesses goals? I'm the guy. Let's talk today and create something great together.
