      eCommerce Development Review from Kelly Johnson

      Since partnering with Bilberry, we have seen a marked improvement in our websites stability and performance. Their team manages our backlogged issues with such efficiency that our monthly development spend has actually decreased. Estimates are consistently accurate, and we appreciate their proactive communication; if a projects scope evolves, they provide an updated estimate for approval before moving forward. Our monthly sprints are now seamless thanks to their reliable planning and ability to scale resources rapidly to meet even the tightest deadlines.

      Web Development Review from Adam Ely, PMP

      As Director of Operations at Sands Investment Group, I partnered with Bilberrry to lead the redesign and rebuild of our website, enhance our marketing operations, and streamline internal workflows. We chose Bilberrry for their strong technical capabilities, cultural alignment, and outstanding reputation. The project followed a well-structured four-phase process: discovery, design, development, and launch. From the beginning, Bilberrry took a strategic and collaborative approach, conducting workshops and technical audits to define a scalable architecture and intuitive user experience. Their team went on to create custom designs for more than 20 pages, build a flexible design system, and ensure the site met key standards for SEO and accessibility.On the development side, they customized a robust content management system tailored to our needs, incorporating dynamic listing features such as saved searches, email alerts, and early-access content for select users. The new site also connected seamlessly with our internal tools, enabling greater efficiency and automation across teams.The impact was immediate and significant: we saw a dramatic reduction in manual processes. Our team is now better equipped to manage content independently, while the platform itself is built for long-term scalability and performance.Throughout the process, Bilberrry was responsive, professional, and incredibly easy to work with. They communicated clearly, incorporated feedback quickly, and consistently brought thoughtful, strategic ideas to the table. Bilberrry's unique blend of strategic insight, technical depth, and design acumen made them an invaluable partner in creating a high-performing, visually polished digital platform tailored to our business.

      eCommerce Development Review from Parker Green

      We initially engaged Digital Insides to get to a particular milestone when we were only about three weeks away from a deadline. They helped us create specific components in the project; we worked on a few while they also worked on critical elements of the site: a blog, a media gallery, a library, and an audio podcast module. Those components were in a particular section of the site; they were utterly siloed in that section. Digital Insides also had to create the APIs to talk to the WordPress backend. Overall, setting up the web was the main scope of work.Digital Insides created their development environment and developed all the components. Once they tested everything, they sent us the code. We already had the design layouts for them, so they didnt have to worry about it. However, we didnt have a mobile layout, so Digital Insides worked on that themselves and adapted it to the rest of the site.
