Banco Internacional - Banking industry
A Century of Financial Leadership
Banco Internacional has been a trusted financial institution serving millions of customers across Latin America for 50 years. But decades of growth and acquisitions left its technology fragmented and outdated, with over 115 legacy systems struggling to meet modern digital banking demands. Facing operational inefficiencies, compliance risks, and mounting infrastructure costs—particularly from a core application running on obsolete .NET 2.0 code, the Bank sought an agile path to the digital era without disrupting day-to-day operations.
The Challenge:
For decades, Banco Internacional operated on an increasingly fragile and costly IT ecosystem. Decades of organic growth and mergers had created a sprawling architecture of over 115 interconnected legacy applications, many of which were undocumented and unsupported. This precarious foundation was compounded by a critical core transaction system locked into obsolete .NET 2.0 code, making it incompatible with modern security standards and browsers. The result was mounting security vulnerabilities, escalating infrastructure costs, and a constant state of "firefighting" that prevented any attempt at innovation.
Specifically, the Bank faced:
- •115+ interconnected legacy applications, many undocumented and unsupported, leading to significant integration risk.
- •A core transaction system locked in .NET 2.0, dependent on obsolete servers, and incompatible with modern browsers like Chrome.
- •High infrastructure costs tied to maintaining obsolete servers and proprietary hardware.
- •Severe security vulnerabilities after 8–10 years without essential patches and updates.
- •Single-person dependency on key systems, risking critical knowledge loss and prolonged downtime.
“We were firefighting every day. Innovation wasn’t even an option”

Our Approach: VelX in Action
Our AI-driven, human-in-the-loop strategy runs through three phases: Explorer, Architect, and Coder:
VelX Explorer – Fast, AI-Powered Discovery
VelX Architect – Smart, Data-Driven Planning
VelX Coder – Human + AI Development
The Proof of Concept
Devsu showcased the modernized transaction running live:
- Teller processed a bank deposit on a modern browser (Chrome) using a new computer.
- Transaction data synchronized instantly with other legacy systems.
- Solution was fully validated by bank staff, meeting compliance and security standards. This proved that phased, AI-assisted modernization could deliver real results fast—without disrupting operations or introducing new risks.
