Barry was great. I was having issues with my screens (3) not working. With a few adjustments I was back up and running. Will be using him again in a couple of weeks to help me set up my new system.

Hi Debbie I believe you left the review on the wrong account. I am glad Barry took great care of you but please make sure the credit goes to the techs who did the work. We love great reviews! Have a great day!

Dalmark was awesome to work with. Within an hour, Ramiro fixed my WiFi issues, cleaned up unknown PC malware and provided me tips on ways to keep my PC operating efficiently and how to better troubleshoot. Five stars! Will definitely ask for his assitance again.

Ramiro Barrera was excellent in his service. He established the home network between a PC, an iMac, and a wireless printer. He stayed longer than anticipated (2 hours) to finish the work.

Absolutely amazing. I needed a power supply installed same day. He came to my house early to install the power supply into my pc. After he was done, he did test the pc to make sure it work. It booted up way fast than before. Highly recommend. Any pc needs, I will contact him.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
Our pricing is transparent and flexible depending on your needs. We offer flat rates for common services, hourly rates for more complex support, and project-based pricing for full-service IT or marketing work. We do not charge hidden fees, and you'll always get a clear estimate before we begin. Discounts may be available for first-time clients, bundled services, or recurring support plans.
What is your typical process for working with a new customer?
We start by listening—whether through a quick call, message, or form—to understand your needs. Once we’ve confirmed the scope, we provide an estimate and timeline. After approval, we schedule service or begin the project. We stay in communication throughout and follow up after to make sure everything meets your expectations. For ongoing clients, we also offer monthly check-ins and support.
What education and/or training do you have that relates to your work?
I hold an Associate Degree in Computer and Network Administration, and I’ve completed specialized training in IT support, network configuration, and cybersecurity. Beyond formal education, I’ve spent over two decades hands-on in the field—building secure networks, solving complex tech issues, and adapting to evolving systems and software.
