    NOW AVAILABLE FOR SHORT TERM PROJECTS ************************************************************ Microsoft Excel Guru For over 10 years I have practically 'lived' in Microsoft Excel. From pivot tables and charts, crazy formulas that most people never use to some pretty hairy VBA hacking (database connections, custom formulas, automated formatting, etc...) my experience with this program runs quite deep. If you are looking for a data entry person, I'm probably not the right candidate. If you need someone to build a custom spreadsheet that combines multiple data sources, automatically formats itself, and *then* makes you a cup of coffee (assuming your coffee pot is Hyper Text Coffee Pot Control Protocol enabled, that is) then I'm your guy. I am optimized for MS Excel 2010 & 2013. Strategic Pricing Price based on the value to your customer, not your costs! Custom development of strategic pricing for new or existing products and services with an emphasis in pricing for the manufacturing sector. I have experience working with Value calculation, Business Development, Engineering, Finance/Accounting, and Procurement functions to identify current and forecasted costs. Market conditions, business goals, and customer profiles are analyzed to determine optimal IRR/Profit percentage and set pricing. Project Management I currently am involved in project management and contract negotiations for a Fortune250 aerospace company. As such I have found that my project management style is a little more thorough and detailed than most software program/project managers. I will spend more time up front understanding the project, the stakeholders and defining what 'good looks like' before we begin executing our plan. Communication is central but must be balanced and minimally invasive to the developer's creativity and productivity. PHP Development My objective is to develop quality web applications that deliver value to my clients and their customers. I accomplish this by carefully choosing jobs that I accept. I have worked with one of the largest data aggregators in the world to develop custom PHP web applications. I know I can bring value to and complete beyond the expectation of the client. If I bid on your job, be assured that I have a plan to solve the problem and make it look GOOD! A PHP developer since 1998 (version 3.x) I am familiar with Object-Oriented Programming skills and design patterns, the PEAR library, Smarty Templating Engine, the Joomla! codebase, osCommerce, CSS 2.x, (X)HTML, and more. I would classify myself as less of a web designer and more of a programmer/developer. I have developed PHP-based web applications for commercial and private customers including a shop-floor control suite for a fortune 250 aerospace firm and a custom CMS for non-profits which is now hosted on Sourceforge.  less
