Linux Support & Consulting for Rosebank – Amazing Customer Testimonials

We experienced some issues with our Linux server. I contacted Luke and explained my concerns, Luke come to our office (after hours) to run some tests and when advised me that some programming was required and that the hard drives were overdue for replacements. Luke suggested I drop the server of at his office on Friday late afternoon so he could do the fix on the weekend and he would come to our office on Sunday afternoon to install the updated server. I gladly accpeted such a great offer. Everything went exactly to plan even though we had to deal with really bad storms and some power outages on that weekend. Job well done.

I was very impressed with the prompt service I received from COLETEK IT. I submitted a request for assistance on Thursday when my Windows PC failed to boot. I dropped the computer off Friday. Saturday - I was notified that analysis was complete and that a reinstall of Windows was required. Sunday - I was notified that Windows had been reinstalled and all my data had been copied back. Monday - I picked up my recovered machine from COLETEK. Four days from initial contact to having my system back would be great service in anyone's book. I have no hesitation in recommending COLETEK IT.

I have outsourced many projects through COLETEK over the years for a variety of applications. Applications such as a online based software platform that pulls live data feeds and updates in real-time to the user. A custom built website for adding users and products that achieved over 20,000 listings. Mobile applications. Data recovery and hardware repair. Custom SEO services and secure hosting services. I choose COLETEK because I know that a job will get done as requested and within a reasonable time frame. Also I'm a stickler for security and they're the best.

I have been working closely with COLETEK for the past 6 years now, and I must say, it is a success story :-). I highly respect their team, they are a pleasure to work with and top skilled professionals. In addition to their top Technical service, their customer service is brilliant and it is a rare find. Their PCB repair rework skills are top notch and a rare find in this industry. I have been working in the IT industry for the past 20 years in various fields and seen it all so I can say with certainty that they are the best around and I am looking forward to keep working with them in the future.

We recently engaged the services of COLETEK to perform some penetration testing on our systems. We found Luke flexible and accommodating with our specific needs. Luke provide what we needed to show our clients our security measures with our systems. I would have no hesitation in recommending Luke.

We've worked with Luke and the team on and off for the past two years. We've found them very accessible and extremely thorough in their dealings. Their documentation is second to none and we’d have no hesitation recommending them on this basis alone.

Luke from COLETEK provided server setup and consultation for our media production Business. They were prompt, professional, and helpful, and gave us some good ideas and options when it came to a custom and cost effective solution. They have been prompt and responsive since initial setup, offering advice as needed and supporting additional requests. Highly recommended!
