Describe the scope of work in detail. Please include a summary of key deliverables.

Our objective was to create a dual-platform mobile app using Flutter. Leancode, known for their expertise in Flutter, came highly recommended. We were impressed by their reviews and skill level. 

The project began with a UX Design Sprint, which led to our decision to engage Leancode for the full development based on their strong communication and design acumen. After successful beta launch to demo testers, we released to stores the MVP version of the app, and are now developing the full version with all planned functionalities.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

The MVP app launch has garnered very positive feedback, particularly for its user-friendly profile creation process.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

Leancode's project management was structured around bi-weekly sprints, which allowed for meticulous planning and regular refinement sessions to finalize features and tasks. While we established milestones well in advance, we encountered some unexpected bugs that necessitated slight adjustments to our final delivery dates. Despite these challenges, the team was proactive in addressing the issues and optimizing solutions in subsequent sprints. 

Throughout the project, we utilized a suite of communication tools, including Slack, Email, Jira, and Figma, complemented by consistent online meetings via Google Meet. This suite of tools facilitated clear and effective communication, which was key to our project's progression.

We were particularly impressed with the professionalism and communication prowess of the Product Owner. The UX designer demonstrated outstanding design and analytical abilities, while the QA team's dedication ensured quality control. Furthermore, the developers' expertise in Flutter was evident and greatly appreciated. Their collective responsiveness to our needs has been commendable, and we are quite pleased with the partnership's results thus far.

• Subscriptions: Regardless of payment source, users can access their accounts on different devices (with different operating systems). Pricing can be managed without app releases, allowing for differentiation prices among users/user groups. Prices for given users may be changed manually or by providing promotion codes to users. 
• Virtual bookmarks: In this case, we used Firestore to enable the storage of information. Users can mark their favorite chapters or see the last played part of the audiobook. The virtual bookmark will remember when a given chapter was paused in the listening session, and the user can continue from that moment the next time it is played back. 
• Multi-language content: The user can choose which language version they prefer (Polish, English, Spanish). The challenge was that from the backend server side, the content was structured uniformly regardless of the language version but depending on the user’s language preferences, we had to present the content differently.

BACKGROUND

Please describe your company and your position there.

I'm a funder of Virium - a SporTech platform and complete system for league and tournament organizers.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire LeanCode, and what were your goals?

We hired LeanCode to create the entire platform from scratch. They provided us with all the technical knowledge we needed, including integration research and IT solution consulting. We were able to translate our business goals into technical architecture. We entrusted LeanCode with full responsibility for organizing the developers' work and managing work stages, which we were fully satisfied with.

SOLUTION

How did you select this vendor and what were the deciding factors?

We’ve had the pleasure of working with LeanCode in previous projects and knew their technical skills. We knew they had extensive knowledge not only of product development but also of available technology solutions.

Describe the scope of work in detail, including the project steps, key deliverables, and technologies used.

We created two Flutter mobile applications - one for the Players and one for Referees on both iOS and Android platforms. We also made two web applications: one for the manager to create and manage Leagues and Tournaments and the other one for Players and Fans to watch competitions.

The web app for the manager was based on design components, and the Players facing application was fully custom-made. Both web applications were made using React. All the backend work was done in the .Net Core. We started the work by creating the Manager application for organizers, a web application for players and fans, and the Referee app. This was the scope of MVP, and it was the solution we sold in the first commercial deployment.

How many people from the vendor's team worked with you, and what were their positions?

We worked with 2 backend developers, 2 frontend developers, 2 mobile developers, and 2 testers.

RESULTS & FEEDBACK

Can you share any measurable outcomes of the project or general feedback about the deliverables?

All the development plans succeeded. We were able to create the entire platform. We managed to build a system for white-label customer deployment from one code base. This was something that LeanCode tech specialists pointed out and made possible.

From the business perspective, we were able to focus on a new client segment - big clients that need their branding on mobile applications. The biggest amateur leagues and tournament organizers in Poland use the system. Any obstacles to the growth of our solution are non-tech related.

Describe their project management style, including communication tools and timeliness.

We worked in Scrum methodology and were able to create MPV within 3 months. It allowed us to deploy Virium to our first customer for commercial use. We used Google Meet for organizing meetings and Slack for everyday communication. We worked in 2-week scrum sprints. We were able to show the first fruits of our labor after 2 months.

What did you find most impressive or unique about this company?

Thanks to cooperation with LeanCode, we could entirely focus on solving our business issues without any fear of the proper implementation of the technical aspects of the project. We could also trust them to solve any technical problems when any arose.

In addition, during the product design workshops with technology experts from LeanCode, we learned that we could implement some parts of the Virium system with solutions that exceeded our expectations and all within the assumed budget. LeanCode's bold advice allowed us to conclude that we don't need some of the functionalities, but from the other side, the key functions were implemented in a way that delighted our clients.

Are there any areas for improvement or something they could have done differently?

I see some changes we would make, but they would be business decisions. If we would, for some reason, had to rebuild the system from scratch, we would use the same technologies and technical concepts.
