The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I’m the director of Lasso R&D Pty Ltd. We develop software systems for the healthcare industry.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire SPUTNIK?

We hired SPUTNIK to develop a mobile app in Xamarin using documentation from our Windows application. We wanted the app to be available for download on iOS and Android devices.

What were your goals for this project?

Aside from developing mobile versions of the app, our goal was to refine the way we incorporate external contractors into our business. We also wanted to find a team that could eventually become part of our long-term development strategy.

SOLUTION

How did you select this vendor?

When we initially spoke with SPUTNIK, we felt comfortable with their team and were impressed by their knowledge. They also had an extensive portfolio and a collection of fantastic references.

We sent them a detailed project scope, and they responded with a proposal in a matter of hours. We selected them because of the strength of their proposal and their experience with CRM development.

Describe the project in detail.

Once we accepted their proposal, SPUTNIK began setting up the project on different project management tools. They quickly sent us screen designs and mockups for us to review, and the team started developing the application immediately after we approved their designs.

What was the team composition?

We’ve had the same team throughout the project. Our team includes a project manager, a designer, several developers, and an account administrator.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

This is our first attempt to use an external contractor for a major development project, and we’ve been pleasantly surprised with the results. We’re expecting that the beta version of the app will be available within the next four weeks.

How effective was the workflow between your team and theirs?

SPUTNIK’s project management style is very effective, and communication has been top-notch. They do an excellent job of managing our expectations and responding to questions and requests.

We use GitHub, Trello, and Zeplin to share project content and updates. During the main development phase, SPUTNIK regularly committed source code to GitHub. We were able to compile the application locally and upload it to our devices for testing.

The team is also very efficient. We received designs in Zeplin within a few days after starting the project.

What did you find most impressive about this company?

Their attention to detail is outstanding. We’ve also been impressed by their ability to effectively collaborate with our developers. We often forget that they’re contractors because they feel like they’re a part of our company.

The team has been exceptionally accommodating and quick to make changes. They were able to overcome obstacles that came about due to discrepancies between the real and test versions of the app. They’re also willing to share their honest opinions regarding the design of the app, and their insights are always useful. The entire experience has exceeded our expectations.

Are there any areas for improvement?

We haven’t noticed any areas of concern. We’re very pleased with how the project has progressed.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I am the general manager of a company that provides solutions for the event industry, mainly the B2B market.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire SPUTNIK?

We hired SPUTNIK to rebuild our iOS lead retrieval app in a multiplatform environment. At that time, the app was only used for single-company events with dedicated iOS hardware. As we were aiming to support the bigger B2B events as well, a multiplatform version was necessary.

What were your goals for this project?

We needed to build a new multiplatform application from scratch, based on the specs and our lessons learned from the previous version. We expected SPUTNIK to help us with the constant improvements and extensions for the app.

SOLUTION

How did you select this vendor?

We did online research and found different companies. We had several calls with each of them and SPUTNIK made a good impression. We started the project and we were confident it was going well. Consequently, our team decided to retain the vendor.

Describe the project in detail.

The solution is a cloud platform used for digital lead retrieval at events—badge scanning, forms and notes, and sharing documentation. It also contains a small registration part.

What was the team composition?

The team includes one manager, one iOS developer, and one Android developer. We’ve also worked with design and testing resources.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

We have a successful product that is now ready to grow. It is working smoothly and user feedback is very positive. As I mentioned before, we keep working on the product to make it better and better; SPUTNIK supports us in that task perfectly.

How effective was the workflow between your team and theirs?

We have an efficient way of working. Communication goes well via all available digital channels including Slack and Github.

What did you find most impressive about this company?

The team is flexible and always available. We strategize collaboratively.

Are there any areas for improvement?

There are always areas for improvement for every company.
