Evooq – Advisory modernization

February 2022 – March 2023

Why

Evooq wants to modernize its Advisory product to reduce its internal costs due to a growing number of clients, and reduce the total cost of ownership on the client’s side. Moving to a cloud solution should contribute to regain control over a majority of the software components, including delivery frequency and observability. Finally, this is an opportunity to raise the bar in order to offer quality daily deliveries.

What

• Feature development on an advisory software solution used by investment businesses.
• Modernization of the existing monolithic advisory software solution to a cloud-ready software product.

Requirements

• To move the current on-premises solution to an hybrid cloud solution.
• To maintain the daily business with the existing clients.

Challenges

• To contribute to the daily business while doing tactical steps of modernization.
• To design tactical modernization steps for reducing the technical debt.
• To improve the experience of end-users, developers, UX-designers, integrators, and QA-engineers.
• To deal with a growing number of clients while maintaining a standard product.
• To deal with heterogenous clients configurations and with different releasing cycles.
