Description

Senior BI (Business Intelligence) Project Developer.

I have been developing BI projects for 18 years in the telecommunications sector.

My specialty is the design and architecture of information systems for business intelligence, keeping up-to-date with new design patterns and data lake implementations.

My strong point is the continuous and comparative study of different solutions offered in the market, both open-source and proprietary, both "on-premise" and Cloud.

I am focused on the technical aspect of systems, not the business aspect.

Current project: development of a DWH (Data Warehouse) for Tigo Nicaragua on Citus/PostgreSQL, a relational and distributed system for structured storage of large volumes of information
