    Good Day and thank you for taking a moment to read my profile! I started working in IT about four years ago as a technical support representative for Simple Helix, a Magento specialist web hosting company. From there, I had the opportunity to spend a year as a Network Analyst for a local, carrier class, ISP before moving on to a position as a Linux Systems Engineer with a Magento development firm. In the present, I work as an Applications Engineer with a focus on the TIBCO stack, most notably AMX, BusinessWorks, EMS, and SilverFabric. I have a very strong background in Linux/Unix administration and have worked extensively with CentOS, Red Hat, and Debian. I've worked with networks from a physical perspective, as a NOC Technican, as well as logical perspective troubleshooting complex application issues. Over the past few months I've taken the opportunity to learn to code in Java and I've recently attended Red Hat training for JBoss EAP 6. I'm a CPTE (Certified Penetration Testing Engineer) and would happily pursue projects as an E-Commerce Architect, Systems Engineer, TIBCO Engineer, JBoss Administrator, entry-level Programmer, or entry-level Ethical Hacker. I am available for new jobs immediately outside of US business hours.

I am a very direct and trustworthy person; I will not waste your time, so I expect you will not waste mine. If you request my services, I will assume you are also aware of my hourly rate; please do not request that I lower it. WOW! That is too high. Well, not really, considering; I have been a independent contractor for over 10 years. The first year, I was charging much lower rates to become competitive on Odesk. I learned real quick to NEVER set your hourly rate to compete with another contractors. I have a base living salary that must be met; just like everyone else, I need to put food on the table for my family. Running a self-employed business, I have business expenses (Insurance, Contractor's License, Training, Office Space, Utilities, Taxes, etc.) for all of which are considered overhead. These are factored in with my hourly rate, if not, I do not meet my base living salary. Here is a great document on how I worked out my hourly rate: http://www.nolo.com/legal-encyclopedia/business-services-charge-how-much-30158.html I enjoy the work I do and I do my best to be as efficient and as productive as I can while always putting the client's interest before my own financial gains. With that being said, I am a sole contracting firm; I run a very successful local profitable business here in Hawaii. I can provide consulting services and remote network engineering skills utilizing Amazon AWS VPC and EC2 network design on VPN, BGP, GRE utilizing VyattaOS. LAN infrastructure - Routers/Switches/Firewall, VLANS, LACP, PAgP,802.1q, RSTP, OSPF, BGP, Trunking, etc. WAN infrastructure - Point to Point DS3 (T3) and DS1 (T1) utilizing ATM and SONET Technology; DSL and cable modem Internet Backup links, Site to Site/Site to Mult-isite and Client to Site VPNs.
