Updating a Complex Legacy System
Our client provides trade compliance software to a global user base of importers and exporters. Its module-based SaaS solution was in need of an extensive update and feature expansion. Sigli refactored the legacy system, modernised core functionality, and added country-specific extensions. The result was a scalable, maintainable platform able to meet the demands of modern, complex supply chains.
30% faster recovery time (after platform disruptions) through improved architecture resilience
65% decrease in bug resolution time due to improved code maintainability
20% cost savings in annual maintenance expenses because of modernised infrastructure
Reduction in time-to-market for new features by an average of 25%, made possible by streamlined development processes

Our client provides tailored SaaS solutions to a global base of over 1000 customers across 55 countries. Its self-stated mission is to “bring all the tools companies need to effectively manage their entire international trade operations into a single location.” It is particularly well-regarded for its comprehensive suite of border customs and compliance management tools, which are built for regional and national use.
Our client serves over 1000 customers that must regularly deal with critical compliance and border customs tasks. Issues in these areas — and their knock-on effects on fast-moving supply chains — are often serious. As such, legacy system limitations pose operational risks to both enterprise users and the broader global trade industry.
An outdated backend was displaying limitations across a range of areas: real-time logistics monitoring, customs classification, origin management, integrations with third-party tools, and more.
Two full-stack engineers, one frontend engineer, and a delivery manager were assigned to the project. They followed a detailed roadmap made up of three stages.
Conduct a thorough system analysis of existing PL/SQL components.Identify modernisation and refactoring priorities.
Set up CI/CD pipelines to ensure smooth, reliable deployments.
Create detailed migration plans for each core module, with timelines and milestones.
Build the foundational system framework using Jakarta EE and MicroProfile, maintaining ecosystem integrations.Develop country-specific library extensions as modular components.
Implement API gateways and service mesh architecture for optimal performance and security.
Execute PL/SQL to microservices conversion while maintaining uninterrupted platform functionality and data integrity.
Integrate modernised services into existing workflows and Oracle database infrastructure.
Conduct comprehensive testing of the platform to guarantee reliability and feature perforRoll out gradually using blue-green deployment strategies to ensure zero-downtime transitions.
The team was made up of four AI engineers, three full-stack engineers, three frontend engineers, and two quality assurance specialists, alongside a solutions Architect and Delivery Manager.Communication was via virtual meetings with key stakeholders. We used email and WhatsApp as always-on channels.
The project followed an Agile methodology, with daily meetings and regular sprint planning, retrospectives and product refinement calls.
Sigli refactored the core platform, extended its feature set, and integrated new modules into the product ecosystem without any unwanted consequences.
Our client saw a range of performance improvements — a 30% boost to recovery speed after disruptions, a 65% reduction in bug resolution time, a 20% saving in maintenance costs, and a 25% cut in time-to-market for new features.
Comprehensively refactored legacy system
