case studies
Numbers, not adjectives.
Each case is anonymized out of respect for the client, but the figures are real. Fixed structure: situation, intervention, numbers and what stayed in the client's hands.
Public university moves to PostgreSQL without a tender
// situation
A public university needed to modernize its institutional system on a tight budget and without going to tender. It ran Oracle 19c and wanted a formal PostgreSQL evaluation before committing.
// intervention
- › Formal Oracle 19c → PostgreSQL evaluation with object inventory and compatibility matrix.
- › PostgreSQL adopted for the institutional system.
- › Implementation with PITR backups and a documented restore test.
- › Local high availability configured and verified.
- › Training for 2 teams (28 hours) contracted separately, as a distinct scope.
// numbers
- ✓ No Oracle licensing on the migrated system: it adopted PostgreSQL.
- ✓ Contracted via direct award (implementation + training).
- ✓ 28 hours of training to 2 internal teams.
// what stayed in the client's hands
The university was left with its database on PostgreSQL, full documentation, verified backups and two teams trained to operate without depending on the consultant.
Customs carrier gets out of audit risk
// situation
A border customs carrier ran two Oracle 11gR2 databases on RHEL 5: out of support and exposed to a licensing audit. The application could not change.
// intervention
- › Migration of two Oracle 11gR2 databases on RHEL 5 to Oracle 19c on modern Linux.
- › Same application, zero functional changes for users.
- › Cutover by location, with a rollback plan tested for each.
// numbers
- ✓ Two out-of-support databases brought to a supported version.
- ✓ Zero functional changes in the application.
- ✓ No exposure to penalties for running an obsolete, unlicensed-risk version.
// what stayed in the client's hands
The client was left with both databases on Oracle 19c over modern Linux, in support and with no version audit exposure, without touching their application.
Sports retailer avoids an ERP re-implementation
// situation
A sports retailer in Monterrey needed operational capabilities NetSuite did not cover out of the box. The alternative they had been pitched was a full, expensive, lengthy re-implementation.
// intervention
- › Custom operational layer over NetSuite: capture for sales reps, management dashboards and import costing.
- › A single integration license, instead of licensing every user.
- › Delivered in fixed-price stages.
// numbers
- ✓ Estimated saving of ~$1.9M MXN in the first year vs. a full re-implementation.
- ✓ One integration license for the whole layer.
- ✓ Delivered in fixed-price stages, no overruns.
// what stayed in the client's hands
The retailer kept its ERP and added the operation it was missing, with its own documented layer delivered in stages, without the cost or risk of re-implementing.
