      I highly recommend Isaac with Techy Toes! I’ve been blessed to have found Isaac and received his services to help promote our plumbing business in Arizona. Within the first 6 months of help Isaac not only had provided us with a fully functioning website but also had worked his magic in getting us to become visible on Google. We have held one of the top three spots in our city on Google Maps for the past 4 years now. The past three years we were awarded the best plumbing company in our city from 3 separate plumbing magazines. We would never have been able to accomplish what we have so far without Isaac. We highly recommend his SEO, Website, and other business related services. He is very honest, patient, and hard working. He will always receive our honor and gratitude for his dedicated hard work and patient understanding. Thank You Isaac and Techy Toes.

      I am very satisfied with Techy Toes Services. Isaac with Techy Toes was able to help make my company, All Drains Emergency Plumbing in Glendale, Arizona one of the top plumbing companies in our city. He was not only able to get our Google Business profile approved for Google, but he was also able to make us visible on Google Maps ascertaining us one of the top three spots on Google Maps in our city which has directly related to our company’s success including giving us a chance to win multiple top plumbing company awards in our city. I will never replace him with another marketer. He is a key core to our company and its continued success. If you are a new company looking for SEO services or help with your website or Google Profile, or Apple profile, or voice search platforms, Isaac with Techy Toes can help tremendously and he is very fair with his pricing. Thank You for all your continued help Isaac! I highly recommend his services.

      Cyber Protect, and its owner Cheyenne Harden, is a wonderful company to work with. Not only is Cheyenne Harden extremely knowledgeable in information, technology, and cybersecurity, but he is also is kind and easy to work with. Him and his company will do everything they can to ensure that your data is secure, protected, and that your technology is running properly. I highly recommend him and his company.

      Cindy L's Review Sourced from Google

      Terrible service. I trusted Cyber Protect LLC to help secure my data, but I still got hacked while under their protection. When I reached out for help, their support was slow, unresponsive, and offered no real solution. They took no accountability and left me to deal with the damage on my own. Completely unreliable and not worth the money. Would never recommend.Edit: Your response is disappointing and frankly evasive. If you have no record of me as a client, maybe that explains why your “protection” failed so miserably. Your slow, unresponsive support and complete lack of accountability left me to deal with the consequences alone. Claiming that neither you nor your clients have ever experienced a breach sounds more like a PR line than reality.If you want to prove otherwise, then start by owning up to your failures instead of brushing off legitimate concerns. Until then, your “enterprise-grade solutions” are nothing but empty words.

Here are some of the QA tests that US .NET development companies employ: 

  • Unit testing: Examines the software’s individual components, including module behavior, code-level functions, and error handling 
  • User acceptance testing: Simulates real-world usage, such as user interaction and how well the app integrates with business processes and workflows 
  • Integration testing: Assesses how the different system components interact with each other, including how data flows and how third-party systems work together 
  • Regression testing: Analyzes the stability and functionality of the app after a bug has been fixed
