Web3 Development Review from Ihor Palteka
We worked with CIDT on building a web3 tax module for our platform. The team created the full backend: blockchain data processing, NFT and DeFi event detection, VAT logic, and reporting. Communication was easy, and we always talked in Slack with regular Zoom calls to check progress. The system works stable and fits well into our product. We had some extra design iterations, but the team handled them quickly. Overall, it was a good and smooth cooperation, and we are happy with the final result.

They managed the entire process - from product architecture and design to backend development and DevOps - with impressive technical precision and attention to detail.
Blockchain Review from Hanna Korovianska
We partnered with CIDT to integrate a cryptocurrency payment module into a custom eCommerce platform we were developing for one of our clients. Our goal was to add a secure and seamless crypto payment option without disrupting the existing checkout flow.The CIDT team handled everything related to blockchain integration from wallet connections and smart contract setup to documentation and testing. Their work was well-structured, efficient, and fully aligned with our development process.A special mention goes to Ramil, CIDTs CTO, whose technical expertise and leadership were outstanding. He guided our team through the blockchain-specific parts of the project, explained complex concepts in simple terms, and helped ensure that the solution was both reliable and easy to maintain.All milestones were delivered on time, communication was smooth, and the final integration performed flawlessly. Within the first three months after launch, over 3% of transactions were completed via crypto payments, with a higher average order value than traditional methods.Overall, working with CIDT was an excellent experience. Theyre a professional, knowledgeable, and trustworthy team, and we look forward to future collaborations.

Web Design Review from Michael John Norton
Working with MultiQOS was a pure pleasure. They were timely, efficient but also kind and patient, particularly when I could not come back to them on comments during the working day. Despite this, the project from the outset was treated with professionalism and for that I have a website that I am now very proud of. Thank you MultiQoS. Would recommend to anyone who wants to design their own website!

Sameer Qurban's Review Sourced from Google
Extremely disappointed with MultiQoS. Waited over 18 days for an estimation, which I never received. And their response was nonexistent. The communication was lacking and unhelpful. Disappointed with the overall service and professionalism. Lack of service and communication raises serious concerns about their reliability. Not a recommended choice.
