Next generation cloud-based asset management

With about 475 employees at locations in Germany, Belgium, France, Italy, the Netherlands and Switzerland, the vwd group (today part of Infront) is an internationally active collection of companies with strong roots in the local financial markets.

The vwd group offers customized information, communication and technology solutions for financial services providers, companies, media operations and private clients.

xitee was building the next-generation cloud-based asset management solution, which replaced the current desktop application (VWD Portfolio manager). The vwd portfolio manager is the perfect portfolio management solution for Private Banking and Wealth Management. The system supports all process steps in portfolio management, from planning through implementation to controlling. It gives the user the benefits of a standard software solution which can be scaled to the needs of the user as required very flexibly, quickly, and cost effectively.

The new platform fully adopts microservice architecture and is part of a larger ecosystem where it also collaborates with numerous other microservices that make it easier for the users to interact with their customers in compliance with regulatory requirements.

xitee was responsible for development of both back-end and front-end part of the system. The back-end team oversees building Position, Transaction, Risk and Performance services which provide data from various existing systems to new web-based front-end.

And the front-end team was building brand new Angular Dashboard & Widget based application to display various information useful for individual investors.

xConvertor – hub for establishing a connection to exchanges

vwd TransactionSolutions AG is a financial brokerage company, which develops, operates and offers financial securities trading and distribution systems. With several important in-house systems, vwd is a key player in the financial brokerage and market connectivity on the European stock exchanges.

xConvertor is a B2B connectivity solution providing customized access to many different stock or energy exchanges as a primary connection for trading. It connects brokers with markets and market makers and converts their communication (e.g., orders, quotes, etc.). The conversion is not only covering different technical interfaces (e.g., various FIX dialects, JSON, etc.), but it also provides business logic conversions. As an example, we compensate differences in message workflows, map and convert differently generated IDs and do other content conversions of the messages.

Application architecture was decided to be a point-to-point bridge with inner routing and generic, highly configurable conversion engine. Specific type of routing differs between plugins. Application supports multiple connections in a single instance and multiple instances running in parallel.

Web application for care consultancy

compass pflegeberatung GmbH is an independent subsidiary of the Association of Private Health Insurance (Verband der Privaten Krankenversicherung = PKV) which fulfills the advisory requirements of all privately insured persons and their relatives. The telephone care advice is open to everyone who needs advice on care. Free and independent. Our team was working on the development of a completely new modern solution (web-application) that allows compass to manage/provide care consultancy in the most effective and user-friendly way.

xitee, together with HBSN Consulting GmbH, supported and accompanied the client compass throughout the entire project, from brainstorming for a user-friendly and intuitive application to the design of application scenarios and the elaboration of technical requirements to the development of the new core application.

The goal of the project was to replace the existing application with a new and modern web and mobile application that would improve the user experience and make it more intuitive. The result was a browser-based application based on Java, Spring Boot, MS SQL and Docker.

This was implemented in a hybrid project management with an interplay of classic and agile procedures. The core application was divided into individual functions that were specified together, taking into account the priority given by compass. This resulted in the content of the backlog for the work packages. Development took place in defined sprints with the aim of delivering an increment after each sprint.

The core application is a completely new development of an individual software, which was specially designed to meet the requirements and wishes of compass. It contains the complete documentation for the care counseling according to § 7a SGB XI and the counseling visits according to § 37 paragraph 3 SGB XI.

The intuitive structure of the system guides the care counselors as users through the entire processes from the creation of new clients in the basic data to making appointments and conducting the counseling on site or on the phone. The versatile functions include, among other things, comprehensive documentation, billing and the creation of invoices, sending of faxes from the system and an associated document management system. Also integrated is the technical solution of a calendar function including synchronization with Outlook. Furthermore, an assessment has been integrated.

For the users, a user-friendly environment and interface is provided in terms of layout and operability for work in the office (web application) and on the move (mobile). Access rights to the individual functionalities have been implemented with a detailed role and authorization concept.

The new development was conducted in 15 months and introduced “in time” in September 2020. Further development to integrate additional functionalities is planned for 2022.

Technologies: Spring Security, OAuth and JWT. Backend is in Java, Gradle, Spring Boot and Hibernate whereas Frontend is in JavaScript and Angular. As API we use Swagger and as servers Tomcat and Nginx. Database used is MS SQL DB Cluster. Realtime search via Elastic.
