    Expert programmer with a math background

    Colombia - Last active: 1 day ago - Tests: 8 - Portfolio: 6

    I'm a programmer (though really a mathematician) with over 10 years of experience developing web & desktop apps. I've been using Python frameworks (like TurboGears2, Flask or Django) for web development for a long time, but I'm also very capable of working on a more traditional stack using WordPress, Drupal or CodeIgniter. I can do frontend development also using HTML/CSS and I'm particularly fond of jQuery for AJAX behavior and in-browser animation. For non-web development I use a lot of Python for scripting and rapid programming and Cairo/GTK+ to build graphical interfaces that are portable between platforms. I'm particularly interested in scientific and math-related software but I can do other kinds of programming. In short: I want to build things I can be proud of.

    Direct Response Sales Copywriter

    United States - Last active: 8 days ago - Tests: 2 - Portfolio: 1

    Want to DOUBLE or TRIPLE YOUR SALES using the only copywriter on Odesk that has proven copy to quintuple (that's 5x) sales by rearranging a handful of words? Online sales is a word game...I know these words and phrases. Do you? If not, read on.... Using personalized training and mentorship by a 7-FIGURE GURU and applying the time-proven sales tactics by the Gods of copy (like John Carlton, Gary Halbert, Frank Kern, and Chris Haddad), you'll run copy that can 2x, 3x, or even 5x your sales (10x-20x if your current copy REALLY sucks!). What could doubling your sales do for YOUR business? Money to outsource more projects? Start-up cash for new income-stream ideas? This is entirely possible if your copywriter understands the KEYS to UNLOCKING maximum buying behaviors...there IS a winning combination that creates a POWERFUL need in customers for your product, turning them into hyper-rabid BUYERS! You will benefit in 1 of 2 major problem areas that most entrepreneurs struggle. And the winners experience: 1) "Conversion Crushing" Sales Letters or Video Sales Scripts that will transform your hesitant, skeptical, or even cynical prospects into crazy, passionate, and loyal buyers. 2) Sales copy surgery (aka Copy Critiques). Take your EXISTING sales copy to boost your conversion rates and take your profits to a whole new level! Your internet sales video or text sales letter will CONVERT more visitors into BUYERS. You just need the right combination of words to make that happen. If you're current CASH FLOW seems more like cash trickle, please contact me.
