Significo 360
Custom web based CRM solution to help a call center company managing thousands of calls every day for multiple partners? No problem.
We worked closely with Significo’s call agents to optimize UX of the app so their work could be done more efficiently. In the end they simply loved it as their job got a lot smoother, easier and productive. From their input we created a beautiful and more important, easy to use design which our web team later turned into functional code.
On the frontend we used React and we developed backend using Laravel PHP.

Limona
We developed this modern and playful website that perfectly represents Limona - premium juice to refresh your hot summer day or spice up your evening mixed into a cocktail. Limona is one of the most popular drinks in this part of Europe and is definitely a must try if you decide to visit Croatia. We enjoyed being a part of their brand redesign with this beautiful website.

Vibe
A complete solution that connects DJs and other music creators with crowds during a concert or a regular night at the club.
We learned a lot during this project as we’ve built the whole backend system, iOS and Android apps for users and creators.
We used Kotlin for Android development, Swift for iOS and Firebase as backend system.

A year ago, we started negotiation with company Firefly Agency for the development of our omnichannel Significo 360 platform.

The project was based on an SLA agreement which part was technical specification. Except specification, we spent a lot of time talking with people who will daily use application.

Please describe your company and your position there.
I'm the founder and CEO of Kod Biro, a software development agency from Zagreb Croatia. We are a small team dedicated to developing products and services for clients all over the world. Lately, we've been focusing on developing our own products in the field of augmented reality.
For what projects/services did your company hire Firefly?
We've developed the Nautical Information Services mobile application for the Croatian Ministry of the sea. Due to our shifting focus on Augmented Reality technologies we've lacked the resources to support the development of new features for the app. We've known Firefly from earlier business interactions and offered them the opportunity to work on further development.
What were your goals for this project?
The goals for the project were to completely rehaul the UI for both Android and iOS applications, implement additional features on the interactive weather map and generally improve the stability of the app due to be compliant with new devices and OS versions.
How did you select Firefly?
We've worked with Firefly earlier that year on a couple of smaller projects and we were really satisfied with their performance - quality, timing, and pricing. We did not consider any other agency when we needed help since we were sure they can deliver.
Describe the project in detail.
The client requests were following: - Implement the new UI for the whole app - Improve existing features on the app (such as add download progress for the weather data download) - Implement new features such as a tap on any point of the map to get the localized weather data across multiple weather parameters (temperature, pressure, UV index, wind speed, and direction etc.) - Known bug fixes and platform optimisations Our designer provided the designs but we've all contributed in the feature planning phase. Firefly proved to be very important in this phase due to their vast experience in developing mobile apps. All of this needed to be done on both iOS and Android platforms and they took the responsibility for interpreting the design and implementing it on two different platforms keeping in line with the standard UI/UX rules for each one.
What was the team composition?
They provided both the project managing and development side (for each platform). The only thing we provided was screen designs. We've kept the communication overhead to the minimum by having only one contact from their side which was very helpful since the deadlines were very short.
Can you share any outcomes from the project that demonstrate progress or success?
Since we do not own the app we do not have access to the internal metrics - downloads, usage etc. However, the clients were very satisfied with the results and are planning even further updates for the app. The one metric we do have access to is the app stability, and after the update the crash-free sessions are well above 99%, compared to the 95% on previous versions. There were several bugs and stability issues due to new OS versions which were handled by Firefly team.
How effective was the workflow between your team and theirs?
We've communicated with their project manager on a daily basis. We were very well informed on the status of the project which in turn gave us the opportunity to sync expectations with our clients regarding the deadline and features that will be available in the new version. We've used Slack as a main channel of communication as well as in-person meetings for the initial phases.
What did you find most impressive about this company?
Their responsiveness and ownership of responsibilities were impressive. There were moments when some request were not clear and they made sure to get all the info they needed on time from us and let us know if something is not adequately defined so that we could communicate it with our clients and ask for additional input.
Are there any areas for improvement?
I would really have to be nitpicky to find things that could have been done significantly better. But if I must, then there was one situation where in the release candidate version there was one bug which I found out and the team missed. It was a relatively minor thing, it required a deeper knowledge of the app workflow and it occurred only on smaller subset of Android devices. Once I let them know they jumped on it and made sure to figure it out and fix as soon as possible.
