I'm Nathan Metcalf.

As a Network Administrator/Linux Engineer with over 12 years’ experience in mixed environments, I have worked with several flavors of Linux and Windows, in many different situations. With a dedication to customer satisfaction, I always seek to employ the best solution for each situation.

• Network Administration
• Linux Administration
• Windows Administration
• Electronic Repairs
• Arduino
• Home Automation
• General Programming
• Troubleshooting

As Network Administrator, my role is to provide reliable and stable ICT systems for all staff and students. When I started at this school their network was flat, had little security or segregation and was not maintainable or scalable. I have implemented 802.x Network Authentication, VLAN Segregation, 3CX VOIP, VMWare host redundancy and solid backup solutions.

NDM.Guru is my personal consulting business. When I moved to the Wimmera, I noticed a severe knowledge gap between farmers and technology. NDM.Guru bridges this gap. One of my favourite projects from NDM.Guru was building a microcontroller solution to replace a irrepairable gearbox controller in an articulated CASE tractor. The customer was unable to source a replacement, I saved the day within a week with little hardware cost and minimal downtime. NDM.Guru allows me to explore my programing and troubleshooting skills in a practicle and profitable manner. From rebuilding control systems for farming equipment to building custom drag strip lights for racing motorbikes. I love the practical challanges NDM.Guru provides me.

As Workshop engineer I provided phone and computer repairs, board level electronics repair. This position allowed me to find my feet in the Wimmera community and start NDM.Guru

I provided Linux consultancy and helped migrate from older Sendmail base mail relays to Microsoft Exchange. I also provided consultancy to a previous employer to help provide tertiary support to their proprietary Linux based service delivery system.

I Designed and wrote a web based CRM tailored for <FMCG>. This provided timely updates from field representatives to product managers and removed several paper based processes. Additionally I provided 1st and 2nd level Network and desktop support.

<Electronics_Service_Provider> utilised a proprietary service delivery system to manage their service technicians and contracts. This system was delivered by a co-location Linux LAMP stack that was maintained by myself. This application required 99% uptime and as such was supported by a BGP based co-location master/slave configuration between two local and interstate datacenters. This provided adequate failover and network redundancy. This service was coordinated by custom BASH scripts and processes written and maintained by myself. As their Seniour Linux Administrator, I was primarily responsible for everything Linux - Code promotions, Linux routers, LAMP, mysql databases, hardware and software diagnosis and support.

As Network Administrator for <local_newspaper> I supported over 150 remote users and provided level 1-3 helpdesk support for their LAN and WAN infrastructure.
