Software Modernization of an eMail Marketing SaaS Application


Task: Within an eMail marketing application (SaaS), used by many leading online stores in North America, a software modernization was required. The existing application suffered from a lack of test coverage of the core functionalities and a monolithic architecture. The modernization aimed at better support for the strategic initiatives of our clients business as well as cost savings for future development of new features and modules within the core application.

Solution: Substantial increase in test coverage of the existing functionality for reducing risks during development. We chose a minimally invasive approach. Modularization of the monolithic architecture in several loosely coupled systems interconnected via services using a Service Oriented Architecture (SOA). Development of additional features as standalone applications and integration into existing service architecture:

  • Functional auditing for increasing application health;
  • Self-service account management with user migration;
  • Optimization of self-service billing by integrating a new API.
  • [...]

Additionally, we have provided a model-based Configuration Management for automatic provisioning of virtualized test environments available within the project.

Video Messaging Platform - Cloud Hosted, Grails Backend


Task: It was required to lift an existing web-application (proof of concept prototype) serving user-generated video messages onto a new architecture. The solution was required to be highly scalable for video recording and -encoding, serving a worldwide user base.

Solution: The solution is based on a Grails backend, hosted in a Cloud environment and widely uses queuing to meet scalability requirements. Queues were implemented for video encoding, antivirus scanning, mail sending, etc. Thanks to that, a client can "fire-and-forget" all long-term processes. Moreover, the REST API is stateless which also results in a scalability boost. External resources (JS, CSS) are minimized and compressed in order to optimize bandwidth usage. The front-end was built using HTML5 to provide rich user experiences and compatibility across desktop- and mobile platforms.

Real-Time Business News System on Grails Basis


Task: Due to missing modularisation it was not possible to enhance the current editing system. It was required to design and develop a system that meets internal performance standards and supports strategic planning.

Solution: Architecture, design, development and test of a Rich Internet Application with a Grails Backend. The solution consolidates many news feeds in near-realtime and with high frequency. Several options for interaction and server push messaging where provided to meet constant stability and scalable user experience. Leading journalists have access to a configurable control-system for automatic processing of incoming and outgoing business news.
