DevIT

Yesterday, our app officially launched on the Apple App Store, and we're thrilled with the result. We've already started populating the platform with content, and everything works and looks exactly as we envisioned. We came to DevIT with a clear concept for the wedding services aggregator, and the team helped us adapt our vision to fit our budget without compromising the core functionality. What really set them apart was their patience in explaining technical decisions to us—coming from the wedding industry rather than software development, having a team that could translate complex concepts into understandable terms made all the difference. Olga, our Team Lead, was especially responsive, thoughtfully addressing our questions even in the evenings and on weekends. The final result exceeded our expectations, and we couldn't be more satisfied with how they guided us through the process.

DevIT handled several backend services built with Node.js, NestJS, and Fastify, including payment integrations, internal APIs, async processing, notification flows, and communication between external services and our main platform. Since our teams worked in parallel, predictability between both sides was critical, and their infrastructure setup made it straightforward to expand functionality later without restructuring the core platform.

DevIT handled the full application layer. React frontend for wallet connection, transaction tracking, and interaction with the platform, and used Node.js with Express to manage API logic and communication with the blockchain layer. They also worked with MongoDB to store off-chain data such as user activity and transaction states. One of the more involved parts was keeping the app state in sync with blockchain events, in a stable way.

DevIT was responsible for the Shopify side, including storefront setup, product logic, and integration with our backend system. They ensured that order and customer data were passed correctly and consistently between both systems. The integration worked reliably after launch, and we didn’t need to revisit or rework the setup. Communication was straightforward, and issues were resolved without delays.

Our overall experience with DevIT was outstanding. The team demonstrated strong technical expertise and hands-on experience, ensuring our platform was fully optimized, stable, and ready to handle high-traffic scenarios. Communication was smooth and timely, with all tasks delivered according to schedule and responses to our requests being prompt and professional. Their structured approach to project management made the workflow predictable and efficient, while their deep understanding of real-world requirements helped us avoid common pitfalls. We were particularly impressed by their ability to translate complex technical requirements into practical solutions, and the project outcomes—improved performance, seamless launches, and reliable stability—exceeded our expectations. Overall, the collaboration was highly effective, and we would confidently recommend DevIT for similar projects.

Our team was rebuilding the analytics infrastructure, and DevIT handled the Shopify side to ensure the store produced clean, structured data. They reviewed event triggers across customer flows, validated transaction data, and adjusted the integration with our data pipeline. Because their implementation was consistent, the migration on our side moved faster and required fewer corrections. Communication stayed practical and focused on resolving concrete technical points rather than over-discussing decisions.

DevIT handled the interface and frontend part of the platform from start to finish. They were involved early, understood how the product should feel for end users, and built the frontend in a way that aligned well with our backend work. Testing was shared between both teams, which helped us spot issues early and keep quality consistent. The project moved forward steadily without unnecessary back and forth.

The developers from DevIT integrated into our workflow quickly and handled their tasks. They helped us deliver new features, improve performance and support the client during key releases. Communication was clear, progress was consistent and the team adapted well to our processes.

Good experience working with DevIT, they are responsive, knowledgeable about Shopify, efficient, and pleasant to work with. I particularly appreciated Andrii's work and communication. Some of the team members have difficult-to-understand English, but overall communication is good.

We worked with DevIT Group on setting up multiple Shopify stores for different regions. Their team configured localized currencies, payment gateways, and shipping providers, while keeping catalog management centralized and easy to maintain. They handled both backend and integration work, tested everything thoroughly, and delivered a system that worked seamlessly for end users. Communication was proactive, timelines were respected, and the overall collaboration felt effortless.

The team that worked on our project could problem solve, understood the severity of this working both desktop and mobile, the quality of their work and how flawless everything was truly couldn't be rivaled!

My overall experience has been excellent. Oleksandra and Anastasia have been incredible to work with — Oleksandra delivered thoughtful, elegant, and highly functional designs that captured every detail of a complex platform, while Anastasia managed the project with clarity, consistency, and professionalism, ensuring everything moved smoothly and stayed on schedule. Their collaboration made the entire design process feel effortless. The project is now moving into the development phase, and thanks to their work, everything is well-prepared for a successful build.

The guys at DevIt not only understood the brief immediately but they also came with heir own ideas, which elevated the project further. Great comms and a really nice team. Exceptional.

The professional of the team from the beginning of the process to the end was unmatched. Their understanding of Shopify and our project allowed them to ask great questions and in turn produce quality work. They met deadlines and worked quickly and we were very happy with our overall engagement with them.

We collaborated on a project for a shared client, where DevIT Group demonstrated their expertise as certified Shopify professionals. While we focused on the redesign, DevIT Group handled the development side. Based on the provided UX/UI designs, their team built the Shopify website, implemented front-end components, configured the backend, ensured responsive design and strong performance, overcame technical limitations, and conducted thorough testing and QA.
