Project Overview

You will join VM.PL to develop a mature, multi-module premium financial platform used by institutions in the wealth management sector. The solution serves as a Financial CRM / advisory system / client portal, supporting advisory processes, end-client interactions, and formal business workflows related to documentation.

The platform has been developed for several years within a unified Java/Kotlin ecosystem, based on a modern cloud-native architecture, with no legacy components. The project follows an end-to-end Kotlin approach (backend + UI built with Vaadin) and includes dynamic document generation (Word, Excel, PowerPoint) using the Aspose (Java) library as part of advisory processes. The cooperation is long-term, with a clearly defined roadmap and a fully equipped development environment.
