A Digital Banking Platform: 100% Digital Onboarding and Real-Time Dashboard by Espresso Labs

The client and the challenge

The client is a financial institution that needed to keep pace with the new generation of digital banks without abandoning the solid base it already had. The challenge combined three fronts that rarely appear together:

• An outdated experience. Account opening relied on manual steps, paperwork, and long lead times, creating friction and losing customers at the very first touchpoint.
• A legacy core. A critical central system, hard to evolve, where every change carried risk — and where downtime is not an option.
• Regulatory and security demands. Every feature involves sensitive data and real money, requiring compliance (such as data-protection rules and central-bank guidelines) and rigorous fraud protection.

As with an investment platform, there was no room for failure here: performance, security, and reliability were prerequisites, not differentiators.

The Espresso Labs approach

Because this was a highly critical system, the project was led by a dedicated technology manager from the start, within Espresso Labs' established flow — design first, engineering second — with frequent meetings to align business rules and anticipate regulatory changes.

The solution was built across three complementary fronts:

1. 100% digital onboarding

We removed account-opening friction with a fully digital flow and automatic validations (documents, registration data, and anti-fraud checks), eliminating manual steps and drastically shortening the time to an active account.

2. Real-time account dashboard

We delivered a consolidated, real-time view — balance, statement, payments, and transactions — with custom reports, so the end customer has full clarity over their account on any device.

3. Core modernization with zero downtime

We migrated the critical monolith to a modular architecture using the strangler fig pattern: we replaced the legacy system piece by piece, in production, without stopping the operation and with no "big bang." This reduced risk and enabled continuous product evolution.

Security and compliance by default

Encryption, access control, audit trails, and data-protection best practices were treated as part of the architecture — not a later adjustment — to meet the demands of a banking environment.

What was delivered

From concept to operation, Espresso Labs delivered:

• A 100% digital account-opening flow with automatic validations;
• A real-time account dashboard, cross-platform, with custom reports;
• The modernization of the legacy core to a modular architecture, with zero downtime during migration;
• A secure, compliant foundation, ready to scale and evolve;
• Ongoing maintenance and evolution from Espresso Labs.

Frequently asked questions

What did Espresso Labs build for the bank? A digital banking platform with 100% digital account opening, a real-time account dashboard, and modernization of the legacy core system, plus ongoing maintenance and evolution.

How was the modernization done without stopping the operation? Through the strangler fig approach: the legacy system was replaced gradually, module by module, in production, ensuring zero downtime and reducing migration risk.

How did the project handle security and compliance? Encryption, access control, audit trails, and data protection were built into the architecture from the start, meeting requirements such as data-protection laws and applicable banking-sector guidelines.

How long does account opening take on the new platform? The 100% digital flow with automatic validations drastically shortens the process compared to the previous manual journey.
