    PHP Web Application Developer: Focused on Zend Framework and APIs

    United States - Last active: 15 days ago - Tests: 4

    I've been in the web development field since 2002, when I started as a programmer/admin for a web hosting company. I've worked on a variety of web applications (generally php/MySQL based) ranging from ecommerce to in-house CMS to data mining/feed processing to integrating APIs and web services. I've worked with a number of PHP frameworks (Zend, CodeIgniter, CakePHP), and generally like working with a MVC design pattern. I've developed web applications from the ground up, as well as modified and added functionality to existing custom in-house systems, opensource applications, and commercial applications. I've worked with various APIs, including: Twilio, Twitter, Foursquare, Amazon, PayPal, Drop.io, Sunlight Labs, EmailYak, and others. I've written wrappers for APIs, as well as written APIs for outside integration into applications I've written. I am comfortable working with other developers and designers. In addition I've been asked to do code review and troubleshooting for projects where I had no active role. My profile on StackOverflow (http://stackoverflow.com/users/45531/tim-lytle) is a good sample of my ability to communicate the details of a development problem/solution. I'm also a Zend Certified Engineer (http://www.zend.com/store/education/certification/yellow-pages.php#show-ClientCandidateID=ZEND011439) with experience administering apache/mysql/php/etc on Linux (and a bit on Windows). Most of my oDesk clients are buyers who need high-level, conceptual requests to be understood and implemented, and the projects are ongoing long-term relationships.

    Experienced MQL4 programmer

    United Kingdom - Last active: 21 days ago - Tests: 13 - Portfolio: 5

    MetaTrader 4 Programmer (MQL4) I'm a professional programmer with over 5 years experience in trading forex and converting / interpreting systems for Expert Advisor automation. As a Company Director (CEO) of over 15 years I always work to high standards in a completely professional and ethical manner. Being UK based, I am fully conversant with the complexities of the English language and can convey complex points in an understandable manner. All indicators, expert advisors and scripts I produce are professionally coded, tested and robust, and include the following as standard (where appropriate): - 4/5 digit broker compatibility - Automatic time zone / offset recognition - Built in error checks - Built in safety features (i.e. Closure of orders where stop loss setting fails) I have previously coded the following complex scenarios which can be readily built into future projects: - Serial number protection linked to varying expiry dates - Restriction of indicators/expert advisors to specific chart types and/or timeframes - Automatic changing of charts to correct timeframes - Lot sizing based on account risk percentages - Spreadbetting compatibility - News avoidance (eg. Stopping trades around high impact releases) - Scraping for retrieving information from web sites / RSS feeds I have developed a robust licencing system which can be encoded into any EA or indicator. It allows on-line authorization, chart and time-frame restrictions plus allows remote changing of EA/indicator settings and variables. Please ask for a demo if you are interested. All expert advisors are coded to provide for enhanced optimization and quick backtesting. As a supplementary service I can create professional looking installers and autorun front ends for installation CD's, USB sticks, etc., including the incorporation of logos and branding graphics. I also have experience writing technical manuals, creating video tutorials and preparing seminars.
