Please describe your company and your position there.
I am a business owner at Smart Fusion Solutions: Business Development - Extend IT teams with talents from Ukraine (IT outsource, outstaff, dedicated teams).
For what projects/services did your company hire Exelor?
I’ve got a request from my client to develop a mobile Delivery solution for iOS and Android in a fixed budget and short terms. I had contacted another software partner first, but native development of two apps was out of the client’s budget, so they recommended me to go with Hybrid mobile app development and refer to Exelor as a reliable software house for that.
What were your goals for this project?
I was trying to find a way to perform the mobile delivery solution under the fixed budget. Therefore, I was looking more for the endpoint proposal with the quality and budget guaranties, rather than MVP first (with limited features) and further development.
How did you select this vendor?
It was a reference from my trusted software partner.
Describe the project in detail.
Exelor was responsible for designing and developing the cross-platform app that would work on iOS and Android devices as well as supporting apps in the future. Therefore, we started from the design first and when everything was put on a Figma prototype and agreed, Exelor moved to the development stage.
What was the team composition?
Our team consists of UI/UX designer, Flutter developers, QA engineer and project manager. The size of the team has varied throughout the entire cooperation depending on our needs, ranging about 2–5.
Can you share any outcomes from the project that demonstrate progress or success?
Both apps launched successfully and under the budget. I really like the app design and the fact that everything was performed on time gives a client a huge business opportunity in the current situation on the local market and world in general. I can say nothing but only positive about my experience with Exelor.
How effective was the workflow between your team and theirs?
From the very beginning, Exelor provides me with a project manager from their part and it was the right step. The PM helped me not only with team management but also with business analysis staff. For communication, we used mostly Slack and Jira.
What did you find most impressive about this company?
Exelor is more than a software development vendor - they’re a trustworthy partner with impressive knowledge and skills. I appreciate their openness and desire to share technical competence.
Are there any areas for improvement?
I can say nothing but only positive about my experience with Exelor.

Please describe your company and your position there.
I’m the CMO at a technology development company located in Western Ukraine. We provide professional teams of web-developers to accomplish complex projects and empower key business processes. The company was founded in 2008, and since then we successfully implemented more than 800 projects.
For what projects/services did your company hire Exelor?
We’ve got a request to develop a mobile e-commerce application both for iOS and Android using the Flutter technology as the client has plans to perform a web application in the near future as well. For this particular project, the client-consultant has decided to use Flutter as the best technology for this request. As Flutter is not among our core expertise we were partnered with Exelor as we have experience working with them previously.
What were your goals for this project?
We were looking for a Flutter development agency with a proven track record to perform the app in pretty tight terms.
How did you select this vendor?
We have already worked with Exelor on another hybrid app development project before and were satisfied with the work they have done.
Describe the project in detail.
From the very beginning, we were looking for the Flutter developers that we can trust and had the luck to partner with Exelor on that as Flutter is among their core expertise. The client had planned to develop an e-commerce app for iOS and Android and wanted to meet some tight terms. So when we received that Exelor was ready to perform the app in 3 months with two developers that had met our expectations as well as the client's one. In this project, we kept management on our side and all development was delivered by Exelor.
What was the team composition?
According to the project terms, we were looking for 2-3 Flutter developers that would be ready to perform the app in 2-3 months, and we were glad to figure out that Exelor would perform the project with 2 devs on time.
Can you share any outcomes from the project that demonstrate progress or success?
It was not a big project but with specific and new technology. We couldn’t perform it in-house therefore we decided to contact Exelor and share the request with them. The client got the app on time, under the desired budget and was very glad about the result.
How effective was the workflow between your team and theirs?
As I mentioned above, we took managing staff on our side and all development was on Exelor. The development process was divided into sprints, during which separate parts of the project were made, so we could see the result of the sprint. For communication purposes, Slack, Jira, and GitHub were used.
What did you find most impressive about this company?
The Exelor is a pretty new player in the software development market but has a great and unique experience with the cross-platform app. They are able to provide good quality solutions under time pressure.
Are there any areas for improvement?
No, we are very pleased with Exelor’s work. The team was experienced, all the deadlines were met and the final client received an app in time.
The company was satisfied with the successful launch of the app. The API levels of the project were upgraded, encouraging the team to introduce more compatible builds. The team had a solid base to expand the app even further, which the company appreciated.
