Testimonials

Custom Admin Panel - SSAutoTech

Nick did a fantastic job on my website!

I had an existing website that was not accessible by anyone other than the original development team. I wanted more overal control of it and wanted the ability to be able to amend things, such as prices, detail updates, content etc,
Nick gladly took on this task and had enhanced my website greatly, allowing me the full freedom and rights with all the content, whilst keeping the overall structure virtually unchanged from the original concept.

I am very grateful for Nicks help and support here!
Highly recommend his services.

Video Course Website - Rise Academy

Working with Nikola was an excellent experience from start to finish. He is incredibly diligent and thorough in his approach. He takes the time to conduct in-depth research and gather all the necessary information to provide the best solutions. Nikola was always supportive, clear, precise, and responsive throughout the project. While we, as clients, sometimes delayed decisions, Nikola was never a blocker—he was a true problem-solver, always proactive in keeping things moving forward.

We are very satisfied with the final product. Nikola provided us with valuable insights and proposed solutions that perfectly met our needs. He was always on time with deliverables and consistently went above and beyond to offer support, quick explanations, and guidance throughout every phase. The final website is exactly what we envisioned, and we continue to rely on him for new pages and future updates as our project evolves. We wouldn't have achieved our goals without his expertise.

IT Mentorship

All praise for Nikola; the IT mentorship was truly a wonderful experience, and he shared a wealth of knowledge with me. Before working with Nikola, I hadn't been involved in IT and didn't even know the basics about computers. As a mentor, he's very motivating and always available, which meant a lot to me. I learned how to create websites and design them under his mentorship.
