Caja Popular San Pablo: new core banking system and policy portal

Caja Popular San Pablo is a savings and credit cooperative founded in 1971 in Mexico. To keep growing with its members, it needs to move away from its legacy core system and run on modern, secure technology it owns.

The challenge

Replacing the core system of a financial institution without stopping operations: branches, cash desks, credit and compliance must keep working every day while the new platform is built and data is migrated.

What we have delivered

Technical assessment of the current system

We analyzed the current system's database in depth in an isolated environment, without touching operations. We delivered an executive report to management with risks and prioritized recommendations, a complete data dictionary, diagrams, documented business rules and the data migration strategy.

Policy portal

An internal portal where staff read manuals, circulars, policies and announcements:

• Protected viewer: documents are shown with a personalized watermark, and the original file can't be downloaded.
• Mandatory reading with deadlines, acknowledgment and automatic reminders.
• Version control and expiry dates, with separate permissions to upload and to publish.
• Reports by department so each manager sees who has read each document.
• Invitation-only access, two-factor authentication for administrators and a tamper-proof activity log.

What we are building now

New core banking system

After mapping the cooperative's branch, cash, credit and compliance processes together with its team, we are building its new core banking system in stages:

• Members: onboarding for adults and minors, and a 360° view of each member.
• Savings and investments: deposits, withdrawals, transfers and term investments.
• Credit and collections: origination, payments and follow-up.
• Cash desk: fast keyboard-driven teller operations, vault and daily cash count.
• Compliance: anti-money-laundering controls, regulatory reporting and an audit log.

The clickable prototype has been validated with the cooperative's team, and we are now building the platform's architecture and foundations. Data migration and a members app come next.

How we work

A single identity across all systems, security by design, infrastructure as code in the cloud, automated deployments and staged deliveries with frequent reviews with the cooperative's team.
