      eCommerce Development Review from Jordan Nassie

      Brandastic.com and their team have done an exceptional job on my various websites projects and other marketing campaigns I have launched. Every person on their team is skilled, professional and has great communication. They helped me do a Photoshoot for my e-commerce products. When I needed custom development for a new feature on my non-profit website they did everything I envisioned. I will continue to work with Brandastic in the future.

      Working with Brandastic to build our businesses website was a seamless experience. As a legal professional, I needed a site that was not only visually impressive but also technically sound for SEO.Their team excels at WordPress development and truly understands how to translate complex service offerings into a user-friendly interface.Since launching, we’ve seen a noticeable improvement in our digital presence. If you’re looking for a top-tier digital marketing agency in Orange County, I highly recommend Justin / Sandy and the rest of the Brandastic team

      I worked at Sileria for an year when it was just an start up and that was one of the best learning experience I ever had. The company has top notch programmers and analyst that can solve any complex business problem. From building enterprise applications, to building 3D games, from building top quality search engine optimized websites to building Internet of Things applications, from top rated mobile apps to robotics, they do it all and they do it with top quality. They have excellent work ethics and a no-compromise policy on quality of the deliverables.

      Kurt Wendt's Review Sourced from Google

      I've worked with Sileria as far back as 1994 - in the very early days of Virtual Reality systems development. They were extremely adept at integrating data glove, trackers and head mounted displays with the VR systems development package. They worked with me on a number of VR projects over the years, along with doing database systems work.KurtOwner @ VR-FX, LLC

Learn more about DesignRush Agency Ranking Methodology.

Sources

DesignRush sustains a directory of over 30,000 agencies categorized by service category, location, expertise, and reviews. We build our database in two ways:

  • Our dedicated team of agency experts actively searches the web for top-performing companies. We then pull information from their websites, online presence, and client testimonials to verify their status and qualifications prior to listing.
  • The agencies listed get notified of their profiles on the website and they can choose to claim it or not, which suggests their availability for more collaborations.

Agencies can also reach out to DesignRush and must go through the verification process prior to being listed.
