Services used: web app development, IT consulting
Our main task was to build an MVP of a FinTech platform with essential features like creating and accepting offer templates, completing the entire process from scratch in just four months. We developed the web application using React and Node.js, with GraphQL to streamline data access and accelerate development. The project included integrating public business information databases for up-to-date contractor information, and choosing Comarch OCR for document scanning and Auth0 for secure authentication and authorization. Our role also involved supporting the client in technology and tool selection, ensuring efficient implementation of required features.

Welliba’s project aimed to expand their platform from a previous proof of concept, starting from scratch with a collaboration between LeanCode and Welliba's internal development team. The project scope included building the app's backend and infrastructure, a mobile application, and four web applications, all utilizing technologies like .NET, Azure, React, and Flutter. A significant focus was placed on data privacy and security, internationalisation for multiple languages, and smooth user authentication through magic links. LeanCode also provided IT consulting, aiding in technology stack decisions and leveraging their previous experience to ensure an efficient and effective development process.

From conducting workshops with the client dedicated to defining the main target groups and mapping user stories, through design implementation, to frontend and backend development - we handled it all.

LeanCode was asked to prepare an app that supports and automates collecting videos performed while doing a nicotine test. The app had to be available on both iOS and Android, so naturally, we picked Flutter for mobile and .NET for the backend. This project also required designing and implementing a video recording and upload process. We also created an admin app that lets administrators review users' videos and manage their payments.
LeanCode helped limit the scope of work to release the app in an iterative and timely manner. We proposed and implemented integration with the shipping & procurement provider to fully automate the order process.
The Audio Bible Superproduction - audio streaming application
The Audio Bible is an audiobook in the form of a radio play launched in February 2015 - lasting about 110 hours, being an audio adaptation of the most popular book in the world - the Holy Bible. This platform offers access to high-quality 3D recordings via a subscription payment model. It contains over 5000 tracks available in 3 languages.
Services used: Mobile App Development, IT Consulting, Product Design.
The earlier version of the Audio Bible app used a partly customed solution from the Audioteka platform. However, it didn’t meet our client's requirements due to inefficient further development. Therefore, we had to start from scratch. Their main goals were: to change the payment model from a one-time purchase to a subscription model, to enable the client to manage prices depending on the user’s location (territory-specific prices), to implement the possibility of using gift codes.
LeanCode created a platform that can be further improved and developed when needed. Our structure allows entering new markets with different languages of content and gives almost endless flexibility regarding pricing adjustments.
Prospector - web application
Prospector’s primary goal is to help sales teams to boost their performance by delivering access to qualified prospects. It saves their time due to pitching their services to people who might be interested in buying. Search Builder is the main part of the Prospector system from the technical perspective. It allows one to walk through the vast list of filters and find companies, contacts, or insights precisely to users' needs.
Services used: Web Development, IT Consulting.
We were asked to rebuild the product that had already been on the market. Our task was to build a new web application for Prospector with a seamless User Experience and consistent User Interface. Additionally, the new Platform required a payment tool for subscriptions and billing. Our client took advantage of our IT Consulting service, so the scope of work included both the development of the app, the analysis of current processes, and a proposal of the new solutions.
LeanCode’s team managed to deliver the application despite the challenges of data migration from legacy solutions. Our cooperation resulted in the system that thousands of Prospector’s clients have already been using.
Mindy - mindfulness application
The Mindfulness industry is a part of the HR Tech industry and is growing rapidly, led by major unicorn players like Headspace and Calm. Mindy would like to follow suit and address the mental needs of employees as a benefit. Mindy is a mindfulness app that allows users to relax and meditate with great content.
Services used: Mobile App Development, IT Consulting, Product Design.
LeanCode was asked to build a state-of-the-art mobile application for iOS and Android. For this project, we have chosen the Flutter framework for mobile app development and .NET Core for the server side. The web-based admin app was built using ReactJS. Using this tech stack, we could focus on the biggest challenge, i.e., providing the unique ease of experiencing the mindfulness app comparable to the very high market standards.
Thanks to cooperating with LeanCode on this project, our Client received the fully functional system together with the infrastructure configuration for commercializing their mental health program. We have delivered a complex IT system within 4 months from the start of the work, which is an unprecedented speed.

Credit Agricole Bank Polska decided to become one of the leaders in digital banking. Their new application offers a unique customer experience and user interface.

HR system for temporary recruitment in HoReCa
In HoReCa business managers struggle to manage the team during the periods of mixed demand with temporary peaks like sponsored parties or weddings. Often the need several people for temporary assignments.

Activy Bike & Run Game
If you decide to work with LeanCode you will experience a lot more than an usual relation between a client and a vendor: -> they understand businesses, not only technology -> they share their experience from building companies and products -> they have empathy combined with responsibility And they are really lean - both for small and big clients. I experienced a long entrepreneurial journey with them. At the beginning as a founder I was the part of the development team working as a full time Product Owner and Manager. At the next stages we included our in-house junior PO and backend developer. It was experimental but works really well as guys from LeaCode are also very open to test new approaches. LeanCode taught us how to build great product effectively. They introduced all the popular tools and frameworks to our team which had zero experience at the beginning. We learnt a lot from them and also got valuable technological inspirations. They are still very engaged in our business!
