Highlights / Intro
GTreasury provides a SaaS treasury and risk management platform for corporations to manage cash and investments. But decades-old architecture and legacy Delphi code were creating costly issues for both customers and support teams.
unosquare partnered with GTreasury to quickly define a vision for a scalable back-end architecture, setting the foundation for their next-generation platform.
Challenge
GTreasury needed to modernize a mission-critical platform without disrupting customers who relied on it daily. The biggest obstacles were:
Dependence on outdated Delphi code and decades-old architecture.
Rising support costs tied to legacy issues.
The absence of a clear modernization roadmap that balanced innovation with business continuity.
Solution
unosquare designed a modernization plan centered on scalability, reliability, and maintainability. In just 8 weeks we:
Outlined a transition strategy and modernization roadmap.
Planned an enterprise web app with dozens of integrations and hundreds of plugins.
Applied a tech stack of Delphi, C#, and SQL Server.
Conducted a detailed plugin census to map usage and prioritize remediation.
This effort was powered by Unosquare’s Centers of Excellence, ensuring that every decision aligned technical precision with strategic intent.
Product Engineering COE connected modernization goals to GTreasury’s broader business priorities, translating technical discovery into a clear, actionable roadmap.
Software Engineering COE defined modernization patterns and best practices to re-architect core systems and retire outdated Delphi components.
Cloud & Infrastructure COE laid the groundwork for a scalable, secure architecture capable of supporting future integrations and continuous delivery.
Data COE supported the plugin census with dependency mapping and analytics, enabling data-driven modernization decisions.
Together, these COEs turned legacy roadblocks into launchpads—laying the foundation for a scalable, resilient, and future-ready GTreasury platform.
