bitcrowd Case Study: DB InfraGo's Box - Die Abholstation on Elixir


Train stations in Germany (2023) 
Train travellers in Germany (2023) 
Packages sent in Germany (2023) 
The Opportunity
Each day, millions of commuters pass through the same train stations on their way to and from work. For Deutsche Bahn, this raised a clear challenge: Stations should be more than transit points. To improve this, they aim to offer added value to travelers and to connect with local businesses.
Why? Because while many retailers already provide Click & Collect services, commuters still have to leave the station to pick up their orders - adding extra time and inconvenience to their daily routine.
What if you could get Click & Collect right at the train station?
By bringing Click & Collect directly to the train platform, Deutsche Bahn transforms stations into convenient pickup hubs. Commuters can collect parcels exactly where they already travel - without waiting for home deliveries or making additional trips to parcel shops. The service requires no app, account, or registration; customers simply use a personal pickup code sent via SMS or email. 
The solution is “Box – Die Abholstation.”
Beyond convenience, the concept also promotes sustainability by reducing delivery routes and emissions in city centers. In partnership with selected providers, the stations can securely handle not only retail parcels but also medicines, rental items, and luggage. “Box – Die Abholstation” turns everyday transit spaces into practical, accessible service points - seamlessly integrating shopping into commuters’ daily lives. 
Connecting with DHL Packstations
DHL Packstations are closely tailored to the company's own use case.
They often do not have a permanent internet connection. While a Packstation is offline, deliveries and pick-ups can still take place, which changes the system status.
This means that any number of change messages can arrive at once at any time. DHL's Packstation API Gateway forms a certain abstraction layer and smooths out the events. However, this also means another status layer that needs to be synchronised. 
 If you have questions about the the processes behind this project, or have a similar project in mind, let's talk! 
Negotiating the specification for a technical product between two corporations the size of Deutsche Bahn and DHL is a complex task.
However, the agility of Bitcrowd's small, resourceful team made the process a success, resulting in an exceptional product. 
The Communication Protocol
bitcrowd's first task was to develop a communication protocol that keeps the status of the Packstations synchronised across the three system boundaries and can handle connection interruptions and status changes in a self-healing manner. 
It quickly became clear to bitcrowd's team of Elixir experts that the communication model between the systems would have to be a stateless protocol of immutable ‘all or nothing’ status requests. 
A desired state change can therefore either be applied in full or must be discarded completely.
However, the discontinuous connection also meant that confirmations could arrive at any time, or only after many days. "Eventually confirmed" became the term of the week  in the dev team. 
API Works
From the outset, bitcrowd's small team demonstrated its ability to keep pace in the collaboration with a large corporation's development department. bitcrowd quickly took the lead in design, coordination, and implementation — achieving an early breakthrough by successfully exchanging the first API messages and status updates.
The breakthrough was soon achieved and the first messages and status changes were exchanged.
To ensure reliable testing, the team built a mock API server that mirrored the Packstation API’s behavior. Using Elixir’s lightweight Agent and GenServer processes, they were able to quickly simulate different states and provide flexible staging environments. 
Are you thinking about a project like this and would like to discuss if Elixir is a good choice for you application, let's have a call! 
 
Under the Umbrella
Elixir allows you to build clearly structured modular monoliths using the Umbrella App concept. In Elixir, an Umbrella App is a project that bundles several independent applications (‘apps’) in a common repository. These individual apps can be developed and tested independently, but share configuration, dependencies and build process. The strict separation between the apps allows the application to be clearly structured. If necessary, the system boundaries can also be used to transfer the individual apps to separate systems. This would also have been possible in other languages, but would have required much more discipline and auxiliary code.
Elixir's good-natured error handling made development easier and faster. The isolation and monitoring of Elixir processes in so-called supervision trees means that errors are limited to sub-processes. The other parts of the application remain stable and performant. This makes debugging much easier. 
Background processes
The architecture of Box – The Pick-up Station requires the effective management of a large number of background processes. Elixir just had the right thing!
Oban is a job processing library for Elixir that reliably manages background jobs via a PostgreSQL database. It supports features such as retries, priorities, scheduling, cron jobs and distributed execution across multiple nodes. Unlike other programming languages, Elixir offers integrated key-value store functionalities that Oban can access. This means that background process control is firmly integrated into the system. It is a significant advantage when such an essential component does not have to be outsourced to external applications such as Redis. 
Phoenix Liveview
Phoenix LiveView is a feature of the Phoenix Framework that enables developers to build interactive web applications without relying heavily on client-side JavaScript. Instead of separating frontend and backend with an API, LiveView keeps UI state on the server and communicates with the browser through a persistent connection. This allows dynamic features such as live validation, search, and dashboards to be implemented primarily in Elixir while still delivering responsive user experiences.
Phoenix LiveView allowed the bitcrowd team to implement the management interfaces without additional front-end frameworks. Nevertheless, the GUIs offer real-time updates and excellent responsiveness. Updates are handled efficiently by sending only small DOM changes to the browser rather than reloading entire pages. Because LiveView runs on the BEAM, each user interface is managed by lightweight processes that scale well and provide strong fault tolerance. 
This architecture simplifies application design and makes real-time features easier to build while keeping the server as the single source of truth. 
If you have not yet looked at Elixir, you are probably missing out. bitcrowd ensures that even your first project is a success.  
When new team members are introduced on the app, they are often enthusiastic about Elixir's clarity. 
Where other programming languages require syntactically complex constructs for error handling, Elixir is largely free of ‘framework noise’.
In fact, developers often praise Elixir as a ‘say what you mean’ programming language. Elixir code is explicit, without the magic typical of Rails, for example, which makes it easier to learn. At the same time, there are many useful abstraction layers.

The product
Research from Charité radiologists was used to train an ML model, aiming to aid clinicians in their diagnosis of various eye conditions. Freed from the manual research of printed text books or searching case history databases, clinicians can now upload MRI scans to the application. They then receive potential diagnoses, along with case history and fully-navigable scans – increasing vital speed and accuracy. 
Based on the initial pitch from the Radioeye research team alongside their prototype click dummy, the Charité’s BIH incubator green-lit the project. Radioeye then looked to us to turn this into a real web application. 
First steps
Our design team quickly understood the project’s vision thanks to Radioeye’s prototype click dummy. Working with their radiographers, we reimagined the app’s userflow and user interface by introducing key concepts to better fit the product to the needs of clinicians. Core functionality was improved with the addition of extra screens and UI states. 
We also undertook several rounds of workshops to refine the process for uploading images, taking care to account for real-world clinicians using the app themselves – while integrating the radiologists’ PACS system (which they use to navigate MRI imaging). 
Refinements
While bitcrowd was working with the radiologists to create the first userflows and wireframes, we introduced the concept of “case triage” to help clinicians use the cases presented to them by the ML algorithm. This meant clinicians could use a “pinned case” list for easy access to  relevant cases – showing suspected matches which could include several different conditions as a differential diagnosis, improving the accuracy, speed, and completeness of the assessment.
Taking on the user’s perspective, we also identified potential friction and points of confusion for clinicians when using the app so we could add extra guidance where needed. 
Prototypes
At this early design stage, we’ll use a click dummy prototype to bring the app to life. Using wireframes, we link each screen to the next with the simple click of a button. Being able to click from screen to screen gives a feel for how the app will work, letting us spot any potential problems.
Very low-fidelity wireframes were used to build the first prototype, which we then updated with increasingly high-fidelity screens as we refined them. Using prototypes to guide our changes during these design iterations allowed us to improve the position and grouping of several UI elements. This made Radioeye’s interface especially clear and straightforward. 
Visual design
While we were working on increasingly high-fidelity designs, we refined the layout to Radioeye’s particular needs. Here the UI needed to be both minimal and highly functional, with a “dark mode” schema to match standard MRI image viewing software.
Of course functionality is key, but it’s also important that the UI looks good! We created variations of their official colours that fit the dark mode design in order to give it a recognisable yet subtle branding. The icon set was carefully chosen for both clarity and character – creating an interface that works well and looks the part. 
Frontend web app
Using the visual designs, userflows, and prototypes, our frontend team went to work on creating a highly-responsive React web application. The component library was organised using Storybook, allowing us to build, test, QA, and refine the UI while simultaneously working on app functionality.
The Radioeye app operates on a range of devices: from the radiology lab's multi-monitor desktop PCs to less powerful laptops and tablets. 
Backend functionality
The web app still needed to be tied to the machine learning technology, so it was designed to make requests to an Elixir API custom-built by bitcrowd’s backend team. The images the web app sends to the API running on the server are passed on to the ML algorithm, with the resulting cases pulled from the database. The relevant cases are then sent to the app and displayed to the clinician. 
Iteration
Radioeye V1 was trialled in hospitals across Berlin. BIH then approached bitcrowd for a second iteration. V2 was conceived with the help of user feedback, offering significant improvements to the UI and overall navigation. A hierarchical list of cases was also added, grouped according to regions of the eye – allowing doctors to leverage the ML results with their own expertise.
V2’s new onboarding flow helped guide new users when using the application, and we improved the transitions between the PACS system and Radioeye. As the screen sizes commonly used by radiologists are squarer in format, we designed a landscape version of the product to enhance the user experience.

Deutsche Bahn Station&Service AG has a large number of properties around their train stations across Germany. They now offer them as flexible office space and meeting rooms, so now the millions of daily travellers can benefit from a country-wide network of flexible workspaces and meeting rooms, and DB makes better use of their train station properties.
The core of the everyworks application is an invoicing and payments system, paired with customer management, a calendaring & booking system, admin user management, and an HTML email notification service. This allows everyworks admins to manage the available spaces, meeting rooms, and desks, schedule bookings and cleaning services, and to manage both customer accounts and their own staff’s access to the system. 
We built the backend of the service in Elixir, taking advantage of the functional programming language’s reliability and precision to create a solid and robust application.  
The application was built with the traditional controller approach, but the more interactive parts of the UI were built using the then-new Phoenix LiveView. This technology allows us to write functionality on the server-side and have the UI update to reflect data changes in a highly-responsive way. It also brings a well-designed and full-featured component system to a backend language, meaning we can create an organised system of rich, encapsulated, and maintainable components. 
Our backend team designed and built the GraphQL API that’s consumed by the everyworks mobile application. Through this, everyworks customers can make bookings and manage their accounts on their phones. Convenient and fast access to the reserved spaces is handled though an invite system, with QR codes generated and sent to each customer and their guests, that are scanned on arrival.
The application is deployed on AWS using Kubernetes, giving us a dependable application environment, lightening fast response times, and industry-leading uptime. 
Customers interact with the service through the mobile app, and through HTML emails. These HTML emails contain their QR codes for each booking, are a always-reliable backup to the mobile app just in case, and provide a simple way for a customer’s guests to access the service without having an account. The emails are everyworks-branded, responsive, and tested on a range of 40+ email clients and platforms. They need to always work and look good, whichever device or email app the customer is using. 
The service started simple. Over the years, we’ve built an expanding offering of services as everyworks grows to accommodate more of their customers’ needs. 
The product started by offering desk spaces available on a per-minute pay-as-you-go basis. Among other new features, we’ve added flat-price meeting rooms with multiple invited attendees, flexible prepaid minute-wallets, day passes, vouchers, and discount campaigns.
These new features have helped everyworks fit more conveniently into their customers’ lives, and attracted new customers from other market segments. 
At the beginning, everyworks was a standalone product for Deutsche Bahn and for us. In the last four years, we’ve built a range of services for DB Station&Service AG, all under the “Digital Marketplace” (DiMa) umbrella. You can read about several of those projects elsewhere in the projects section of the website.
Moving everyworks into the same codebase as all the other DiMa services increasingly made sense, though it was clear it would be no small task. The move took quite some developer time, and has paid off, with reduced maintenance, increased reliability, and improved UI as the everyworks admin screens got upgraded with all the features that we’d developed in the time we’d been building those other products. Since the switch, adding new features has been more straightforward and well-integrated.
