Challenge
Nordic Trustee needed to modernise the outdated Tillit core system and its ecosystem of four dependent applications to support the introduction of new services, including Direct Lending. Jit provided estimates, took ownership of the modernisation, rebuilt the system from scratch, supported complex data migration, and helped transform the solution from a desktop application into a cloud-based platform.
The migration involved large volumes of business data and required strong verification of the migrated information. Nordic Trustee’s existing central system was outdated and difficult to maintain or develop further. The legacy solution had a large, complex and intertwined codebase with numerous dependencies.
Modernisation needed to cover not only the core system, but also the full ecosystem of four dependent applications. The system was critical and complex, which made the work difficult to estimate and undertake. The legacy setup limited Nordic Trustee’s ability to introduce new services such as Direct Lending.
What We Proposed
- 1 A full modernisation of the Tillit core system together with the wider application ecosystem.
- 2 A rebuild of the legacy solution from scratch, replacing the existing structure with modular and service-based components.
- 3 A new foundation for services such as Direct Lending, starting with the least supported area of the existing system.
- 4 A cloud-based application improving accessibility for employees from different devices.
- 5 A structured data migration approach, including analysis, mapping, transfer and accuracy verification.
- 6 Transparent project governance and reporting to keep sponsors, product owners, IT leads and delivery teams aligned.
How We Implemented It
- Provided the estimates needed to start the modernisation and took ownership of a highly complex initiative.
- Rewrote the central system from scratch and restructured it into modules and services to simplify future maintenance.
- Started with the Direct Lending module and introduced a three-level structure for storing and managing deals.
- Developed key Direct Lending capabilities, including interest calculation, notification document generation, interest schedule generation and floating-rate update tooling.
- Continued with rewriting functionality related to bonds, which are a core service of Nordic Trustee.
- Migrated large volumes of data by analysing database tables, preparing mappings, transferring data and verifying migration accuracy.
- Moved the solution from a desktop application to a cloud-based application, increasing its business value and accessibility.
- Maintained transparent delivery through steering committee meetings, demo meetings and daily stand-ups.
- Established delivery standards around tracking, transparency, modular architecture, cloud migration and data migration reconciliation.
