They worked on providing us with a comprehensive data architecture designed for scalability and security. A BI dashboard was created that allowed us to visualize key metrics from all our clients in one place, making it easier for us to get a comprehensive overview of our operations.

Shopify Plus eCommerce Review from Jessica Grant
Bighorn has been an exceptional partner to our organization here at Sports Basement. They supported us through multiple legal and regulatory accessibility matters with a steady, knowledgeable approach, translating complex requirements into clear, actionable guidance. Throughout these engagements, their team demonstrated a strong understanding of both the legal landscape and the practical realities of building and maintaining accessible digital experiences, which gave us confidence at every step.
What truly distinguishes them is that their work goes well beyond compliance. In addition to helping us identify and prioritize accessibility issues, they invested time in educating our teams on how to design and develop accessibility into our site from the start. Their recommendations are thoughtful, pragmatic, and focused on real user impact, enabling us to move from a reactive posture to a more proactive, sustainable accessibility practice.
Most importantly, they operate as true partners rather than transactional consultants. Their work is clearly driven by a genuine commitment to making the web usable by all, not simply meeting minimum standards or checking a box. We would strongly recommend them to any organization looking for a strategic accessibility partner who combines expertise, integrity, and a long-term perspective.

As a lead generation agency, we required custom software development to streamline our operations and enhance our capabilities. Bighorn Web Solutions far exceeded our highest expectations. Their team's hands-on, white-glove approach was evident from the start, and their level of competency truly set them apart.

Thanks to their expertise, weve gained not only a top-tier software solution but also a valuable long-term partner. We couldn't be more satisfied with the outcome and highly recommend Bighorn Web Solutions for their superior service and dedication.

Staff Augmentation Review from Dzmitry Novikau
I worked with Kernelics on a crypto project where we needed help with both design and development. From the beginning, the team was easy to communicate with and clearly understood what we were trying to build.
The designer improved our initial ideas by making the user experience more intuitive. They suggested better ways to structure the navigation and user flow, which helped reduce friction and made the product easier to use.
We also brought in one of their developers, who worked alongside our existing team member. They collaborated well, completed the work on time, and handled some challenging parts of the exchange functionality without any issues.
Overall, Kernelics delivered quality work, stayed within budget, and were professional throughout the process. I’d recommend them to others looking for a reliable design and development partner, especially for crypto or fintech projects.

Web Development Review from Stsiapan Kolesau
I CEO at the construction company specializing in modular buildings and their components. With years of experience and multiple projects, we decided to expand our online presence beyond our two existing landing pages. We needed a corporate portal to showcase products, manage content easily, and dynamically calculate product costs.
On a recommendation, we chose Kernelics, and their organized approach and clear task division impressed us from the start. They began with an in-depth analysis of our needs and a competitive review. For the design, we requested a minimalist style, and the results were spot on, requiring only minor tweaks to meet our expectations.
For development, Kernelics selected React, Next.js, and TypeScript, with Strapi for the admin panel. They also integrated Google Sheets to handle dynamic price calculations, enabling instant updates on the site by simply modifying the spreadsheeta feature weve found incredibly useful.
Now, two years later, the portal continues to support our growth, and were planning new developments for our main site.
Kernelics stood out for their transparent approach and professionalism at every stage, and I confidently recommend them to anyone seeking a reliable web development partner.

Mobile App Development Review from Mark Joy
Dima S. responded to one of my job postings on Upwork for creating an audio-related application. He explained the estimated cost of developing such an app, and advised that it would be much more costly than I had anticipated. I was not familiar at all with the costs associated with developing apps, so his explanation was very helpful.
He saved me money by going above and beyond to research existing apps that provided similar functionality to the requirements I was seeking. He also found instructions for using native Apple settings for audio that would solve my problem. The settings he found even allowed import of an audiogram that I had gotten at the audiologist for my specifc problem.
Though he did not end up developing an app for me, Dima saved me a ton of money by spending his time to research possible existing solutions which I had not found during my own search.
I would highly recommend Dima for his level of care for projects and his customers.

WordPress Website Design Review from Anna Abdulova
Working with CitrusDev was very comfortable and convenient.
CitrusDev developed a website (WordPress) for me with the services I provide to my clients.
Since I have a shortage of time, it was important that the team did not need my constant involvement in the process.
After discussing all the details, we met a few times to decide on further actions and make corrections.
The work format was convenient and clear. And most importantly, it was flexible.
The team responded quickly when changes were needed and gave advice for better results.
I am happy with our joint project and want to thank CitrusDev for their professionalism and ease of work.
Thank you.
And I recommend them.
