    I have been in the computer industry professionally since 1984. I have seen MANY changes. I have had just about every position in an IT department and loved each one. I am great at analyzing business requirements and translating them into cost-effective solutions. Mobile Apps, Cloud Computing, e- and m-commerce websites are where I am focusing my attentions primarily. I will gather the requirements and project manage a team of developers from the pool of 1200 off-shore developers I have. Average cost per hour will be $35 for an off-shore developer. Fixed fee projects are also possible. I enjoy group projects as well -- find me 5 companies in the same industry and we will develop a more robust solution at a fraction of the cost! If you need me to come in and assess your business and IT department on a short-term consulting basis, I am happy to do that as well. I look forward to helping you...

    Jeremy Berglund

    IT Manager with VMware and web server experience

    United States - Last active: 10/09/2013 - Tests: 1

    After spending ten years working as the Director of IT for Perteet Inc. (a Transportation design and planning firm in Everett, wa), I have decided to pursue a full time freelance career. I am experienced managing all aspects of the IT environment from business processes and policies to systems administration. While I was at Perteet I was part of the management team and was a key part of the day to day operation of the business. I assisted in policy development and oversaw the implementation of an ERP/CRM system and multiple document management databases. I also was responsible for vendor management and negotiated contracts. At Perteet I lead a team of individuals who were responsible for all aspects of the network from data management to desktop support. I am competent operating VMware vSphere and Hyper-V in SAN environments with fault tolerance, replication, and backup. I have extensive knowledge of Microsoft server technologies including Active Directory, Exchange, Sharepoint, IIS and SQL. I also know how to configure and administer routers, switches, firewalls and other networking technologies. Between 2008 and 2013 I owned and operated a web hosting business that supported the web design clients that my colleague worked with. During that time I hosted over a hundred different web domains (email, mySQL, web) on an Ubuntu Linux web server running on VMware. All software was free and open source. I am seeking short term engagements where I can gain more experience working freelance remotely over the internet. I am interested in implementation projects, project planning, troubleshooting, management, and other opportunities. I am available to work immediately.
