IT Infrastructure | Virtualization | Application Delivery | Networking | Storage

About this blog… and me…

Tech Talk Pro is a blog about IT infrastructure technologies focusing on virtualization, application delivery and data networking. The blog was created, and is maintained by myself, John Gallacher. Like most, if not all IT folks, I have gained much knowledge and support from various blogs over the years, so I decided to start my own so I could give something back to the community. Having a busy day job and an awesome family does limit my ‘blogging’ time, but I hope to add some valuable content whether it be how to guides, troubleshooting techniques, general notes from the field and the occasional opinion on current and emerging technologies.

I have over 10 years experience working as an IT professional, starting out in web development before making the jump into systems support where I fulfilled many roles from desktop support and service desk management, progressing through to an infrastructure specialist where systems architecture & design, escalations and technical consulting are my main objectives.

I’m currently working as a Senior Infrastructure Engineer for a Sydney based systems integrator and MSP, specializing in Microsoft and Citrix solutions design, implementation and support across a variety of industries including financial services, government, broadcast/media, not-for-profit, manufacturing & engineering. This role gives me the opportunity to work on a wide range of clients from SMB to the enterprise with varied technical requirements incorporating multiple platforms and cutting edge datacenter technologies.
