    If you don't have IT or software project experience, please don't contact me (unless you're a trusting adventure-seeker :) Bring Your Own Designer! IT Industry Knowledge Includes: - Best-practice Design & Implementation - B2B & B2C e-commerce - Systems Automation - BPR/Workflows- SaaS/Web 2.0 - Cobranding Vertical Industry Knowledge Includes: - Real Estate, Construction and Manufacturing management systems - Insurance (workflow) - Digital Media (distribution and conversion automation) - Healthcare (data collection & management) Some Background Information: - I have designed, implemented, and administered a wide variety of m$ft infrastructures, operating systems, servers, and applications for over 10 years. - I manage Apache, NFS, Samba, Asterisk, Bind, and other services on Red Hat-esque (CentOS, Fedora) servers. - I have been working with .Net since it was in beta. Before getting into C#, I used VB.Net for several years. - I've been writing enterprise-scale business and data layer code for over 4 years. - I've been managing and programming Microsoft SQL Server since version 6.5 (and am up to date on 200X), and Microsoft Access for many years. - I've worked with MySQL/SQLite and PHP (4+) as a hobbyist for several years. I can perform most any task required to update an existing site, but am probably not suited for a new development project in PHP.- Prior to .Net I programmed in traditional asp using VB Script, COM & DTC. - I manage my own dedicated windows 2k3/8 servers with multiple running applications and servers. - I have experience with a wide variety of third-party components and controls., and can assist in integration, middleware, queuing services, etc. - I'm not a graphic designer, and prefer to leave site layouts and graphics to someone more suited to that type of work. I am ok with creating basic layouts (and working within the popular graphics editing programs), but for a polished look, I'll either work with your designer or contract to another party on your behalf to acheive the look that you're after. Getting What You Pay For: Sure, you can find loads of developers here and on other similar service sites at a fraction of my rates. Why would you pay me? - I will stand behind my work. If you're unhappy, we'll fix it. - I will not charge for time spent figuring out how to solve general technical problems. If I don't already know how to implement a relevant solution, I will spend MY time researching and figuring it out. We're supposed to be professionals, and if we don't understand what the problem is, we shouldn't be charging you. Besides: each time I solve a unique problem, it makes me more effective; for you, me, and my next happy client! NOTE: Most of my work is done for companies' internal intranet, operations and LOB applications. I've added a few items to the portfolio, but please ask me about the other work which I can't showcase. While I'm often bound by NDA/Confidentiality agreements, I can explain more about my background in a general way than is illustrated publicly.

    Nicaragua - Last active: 09/06/2012 - Tests: 12 - Portfolio: 1

    With nearly three decades of experience in the computer field there is almost no technology that I have not investigated and used. A range of employers from military to government and private sector have provided me with unique opportunities to develop my potential and I have always embraced this with enthusiasm. I have used every generation of hardware since my first computer (TRS-80 CoCo) and software as well. This includes legacy systems such as the "Big Iron" mainframes of days long ago and the cryptic ways of JCL, COBOL and 3270 all the way up to our modern paradigm. The last three years I have been busy building Nica Geeks, SA, a computer services company based in Nicaragua. The experience of starting and running my own business combined with my technical skills has greatly increased my overall professional effectiveness.Specific skills I have used recently include:Business management, Team Management, Systems Architecture, SharePoint, Windows server 2003 and 2008, Windows XP, Vista,7, MS SQL, MySQL, Office 2007, Mikrotik, Ubiquiti, VPN, VOIP, Joomla, WordPress, LAMPIt is my intention to establish a thriving online business in this relatively new model of remote working by applying the classic combination of outstanding service at a fair price.

    Windows/Linux/Mac Developer & Consultant

    United States - Last active: 02/18/2013 - Tests: 6 - Portfolio: 9

    I am an IT consultant based in the Austin, Texas area who enjoys working with and leading small teams to success. My work is based on Five Rules: Rule #1: Technology should always serve the end user and the needs of the business. To the extent any technology/solution fails to satisfy this rule, it is a temporary solution and an opportunity for improvement. Rule#2: In business, I.T. is overhead; the less I.T. costs to setup and maintain, the more successful its support team was in choosing their solutions. Rule #3: Good solutions are well documented and easy to understand. "Undocumented genius" and "confusing solutions" are contradictions. Rule #4: When you don't know what you are doing, ask. When there is no one to ask: Backup, work neatly, take good notes and communicate with everyone involved. Rule #5: Complexity kills. Keep IT simple, keep IT clean.
