    Web Application Developer

    United States - Last active: 1 month ago - Tests: 2 - Portfolio: 1

    Hello! I'm a web application developer experienced in HTML5, CSS3, Javascript, Backbone, jQuery, PHP 5.3/MySQL, and Java, among others. I love creating rock-solid quality code that's well commented, bug-free, and that works flawlessly on all browsers. I utilize the latest object-oriented analysis and design principals such as encapsulation, design patterns, and refactoring to make clean, reusable code. I LIVE for the feeling of just having demolished a tough programming challenge with a beautiful, elegant solution. I still make it a goal to read regularly on the latest programming technologies. I'm constantly improving, and I routinely teach myself APIs, frameworks, and even entire language depending on what the challenge calls for. I can also dig into even the most complex code bases to squash bugs or refactor. I'm friendly, cooperative, and encouraging, and I make sure I understand employer's and teammates' goals so we can do everything possible to achieve them. I can work independently and create solutions from concept to completion, or I can work with a team with specific design goals. I ask questions early and often so the product meets the design specs as closely as possible. Overall, I love the challenge and reward of programming, and would be delighted to work with you on your next project.

    Writer/Editor (comedy is my specialty), Actor/Voice Actor

    United States - Last active: 1 month ago - Tests: 4 - Portfolio: 20

    If you need something to be written, particularly something funny or entertaining, I can guarantee it in advance. I work fast and I accept nothing less than my best. I can produce comedy in any form- I write news articles, scripts for sitcoms, films, and short films, websites, etc. I'm also one of the top 5 greatest actors of all-time; most of the voices in that video next to this are mine. There's also a V.O. reel, as well as two editing ones, in my portfolio. I spent two years in Hollywood pursuing comedy writing. In the spring of 2012 I won Best Comedy at the 10th annual DIY Film Festival for a film I made 100% on my own (played every part, was the entire crew). In the past two years, I've published something like 55 videos that've gotten in excess of 20 million views (I've lost track). I do everything for these videos except for the animating. I write the scripts, find the actors, direct them, do my own voice acting (make my wife do voice work, as well), edit the audio, direct my animators (who live in 3rd world countries), edit their animations, and voila- an animation made for a few hundred bucks that 100k people will see in the first month. I wish I didn't have to be a one-man crew (minus the animating), but my standards are too high for amateurs, and professionals are just that- professionals working in the industry (not for freelancers with small, per-episode budgets like me). So, yeah- hire me and whatever it is you need, I'll exceed your expectations. Because if I don't exceed yours, then I haven't met my own. I'm internally motivated- my motivation comes from within. I don't work to get paid, I work to accomplish my goal, which is for my work to blow you away. It's like giving someone a Christmas gift and seeing their eyes light up when they open it- you're like, "yes! Nailed it!" If you get my work and are like, "yeah, this'll do," that's devastating- I want to see those eyes light up and know I nailed it. Oh, and I'm also good at over-explaining stuff. Meaning, I tend to explain more than is necessary to get the point across. In other words, so much explaining that it goes over the amount of explaining that was necessary.
