DevIT Reviews & Testimonials

Web Development Review from Ross Burylo
We worked with DevIT on a web application for one of our clients. We already had the product concept and design direction in place, and DevIT joined as our development partner. Their team handled the frontend and backend development, API integrations, and turned our designs into a working product. The collaboration was straightforward, and they helped us move the project from design to production without expanding our internal development team.

Applications Review from Denis Khorolsky
We worked with DevIT on a Shopify app for one of our ecommerce clients. The app handled product personalization, pricing rules, and personalized order data, while our team worked on the main Shopify platform and customer experience. The teams worked well together, and the client was able to launch the new feature without changing the existing store.

Small Businesses Website Development Review from Oleksandr Romanov
We worked together with DevIT Group on a financial operations platform for a shared client. Our team focused more on the core product and Python backend, while DevIT handled the infrastructure side using Node.js services built with NestJS and Fastify.They worked on integrations, payment flows, internal APIs, notifications, and async processing between different services. A lot of the project depended on things working reliably in the background, and their part stayed stable even as new integrations were added later.The collaboration felt pretty easy overall. Most discussions were direct and technical, without too much unnecessary process around them.

Inspire Visual Reviews & Testimonials

Mobile App Development Review from Rob Dawson
We originally worked with another app agency, but weren't happy with them so we found Inspire Visual. The difference in communication and professionalism were remarkable. With Inspire Visual we received concise milestones with explanations of each phase. They build an iOS and Android app for us and we left it to them to choose the technology (React Native). They have a strong team so we felt comfortable the entire development cycle and ended up with a great hybrid app.

Mobile App Development Review from Richard Wilson
We originally asked Inspire Visual for help with our website and it turned out to be a successful partnership. When we decided to have an app built, we didn't have to look elsewhere for an agency. They were very detail-oriented and talked us through the process knowing we had absolutely no experience with app development. Our project manager was checking in with us regularly. Needless to say, since the app was completed, we've only heard rave reviews from everyone who has used it.

Mobile App Development Review from Jessica Reiner
They were one out of a handful of other vendors we considered during the RFP process. What set Inspire Visual apart was their customer service, attention to detail and their portfolio of previous work. They built a custom team for us with a dedicated project management contact assigned, as well as a team of designers, coders and QA experts. Inspire Visual was more creative and flexible than we have previous experienced and changes happened faster than when we've worked with large agencies.

James Carter's Review Sourced from Google
Our company aimed to launch a trading platform but struggled with security planning and system performance. Debut Infotech supported us with crypto exchange development services using Node.js, blockchain integration, and secure wallet APIs. Their solution helped us deploy a stable exchange environment with improved transaction handling.
Andrew Ethan R.'s Review Sourced from Google
Debut Infotech efficiently addressed the performance and scalability challenges in our mobile app. They quickly diagnosed the issues and delivered a stable solution using up-to-date development tools. The project was completed on time with clear communication throughout.
Blunt David's Review Sourced from Google
I had the pleasure of working with Debut Infotech for DeFi development, and I am extremely satisfied with their expertise and service. Their team utilized a comprehensive suite of tools, including smart contract generators, DeFi protocol integrators, and liquidity pool management tools, all of which streamlined the development process. They not only helped us build secure and scalable decentralized finance solutions, but also provided automated yield farming and staking platforms that significantly boosted user engagement. Their focus on security, with built-in auditing tools, gave me confidence throughout the project. I highly recommend Debut Infotech to anyone looking for reliable, efficient, and innovative DeFi development.

Buildfire Reviews & Testimonials
Eric Vardakis's Review Sourced from Google
I have been using the buildfire mobile app platform for over 3 years now, and this platform is amazing. I've tried other platforms. But, nothing comes close to Buildfire. The features and additional functionality are far superior than any other app platform on the market. With this platform I'm able to provide many options for my clients throughout a list of industries. But, what makes Buildfire reflect superior status is their customer support. Both Sean Hamasha my account manager and Mark Wyatt my customer support specialist are a pleasure to work with. Each of them provide different roles helping me. When I reach out for support I get an immediate follow up on my questions. If I have any technical glitches Mark is always responsive and can't do enough to make sure my apps are running smoothly. When I have any requests for guidance on how certain features can be used, or helping me with structural plans for my business, Sean is always there to guide me through. As a business owner in the media industry for over 30 years, I've always said your employees are a reflection of your brand, and both Sean and Mark are what makes Buildfire the brand they are today. Thanks to both Sean and Mark for all your continued support, and I appreciate all that you do to help my business grow using the Buildfire Platform, and I look forward to working with this great company for many years to come.Sincerely,Eric

I've had an AMAZING experience with BuildFire since the beginning, from our initial negotiations, through the app development, and even now, as I reach out OFTEN for guidance as I work to market and sell my product. Sam has been ESPECIALLY helpful as he answers every question, even before I finish writing them. I therefore HIGHLY RECOMMEND BuildFire to individuals and businesses seeking to build an app!!!

Buildfire was a great platform to get our App online without a big budget. As a really small charity, we could still build - experiment - and deploy with the help of their great development and support team. We've had custom development to keep improving, and the response by our account manager has always been great.
