Kernelics Reviews & Testimonials

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.

I recently completed a Quality Assurance internship at Net Solutions, and it was a fantastic experience. I had the opportunity to work alongside a highly skilled team that truly values precision and innovation. From manual testing to getting hands-on with automation tools, the mentorship I received helped me bridge the gap between academic theory and real-world application. The culture is collaborative, and I felt like a valued member of the team from day one. Highly recommended for anyone looking to kickstart their career in QA

What certifications should a United Kingdom website development agency have?
A United Kingdom website development agency should have certifications related to legal compliance and information security to demonstrate professionalism and adherence to best practices.
Key credentials include:
ISO 27001 for information security
ISO 9001 for quality management
Cyber Essentials or Cyber Essentials Plus for UK-specific cybersecurity assurance
It’s also helpful if the team holds platform-specific or developer certifications, such as AWS, Azure, GoogleCloud, Adobe, or recognized frontend/backend development credentials. Membership in professional bodies like BCS (The Chartered Institute for IT) further signals credibility and adherence to industry best practices.
How long does a typical web development project take?
A typical web development project takes 6-12 weeks, depending on the site’s size, features, and design complexity. Simple brochure-style websites may be completed in 3-6 weeks, while more advanced sites with custom functionality or integrations take longer.
Content readiness, feedback speed, and revision cycles also affect the timelines. eCommerce platforms or custom web applications can extend to 3-6 months or more due to testing, optimization, and deployment requirements.
What happens after a website development project finishes?
After a website development project finishes, the agency typically conducts final testing, qualityassurance, and launchsupport to make sure the site works smoothly across all devices and browsers. They also hand over credentials, documentation, and training so your team can manage the site confidently.
Most companies offer ongoingmaintenance, securityupdates, backups, and performancemonitoring to keep the website stable and up to date. You can also choose optional services like content updates, feature enhancements, and SEO support to continue improving your site after launch.
Do web development companies in the United Kingdom offer fixed-price packages?
Yes, many UK web development companies offer fixed-price packages. When you consider a fixed-price package, make sure:
The scope and deliverables are clearly defined upfront
Payment terms, revisions, and any additional costs are transparent
There’s clarity on what happens if the project scope changes or grows
Can web development agencies in the United Kingdom work within tight deadlines?
Yes, many web development agencies in the United Kingdom can work within tight deadlines, especially when dealing with well-defined projects or smaller websites. They often streamline timelines by allocating extra resources, using proven frameworks, and following efficient project management processes.
The ability to meet a fast turnaround depends on project complexity, content readiness, and how quickly you provide feedback. For urgent projects, agencies may offer expedited services at a higher rate to ensure quality isn’t compromised.
