Executive profile

Technology leadership for high-reliability telecom operations

I’m a senior systems analyst and IT consultant with more than three decades of experience supporting the technology foundations of telecommunications operations. My work spans billing systems, data integration, system architecture, platform modernization, reporting, and production support.

I bring particular depth in prepaid and postpaid billing platforms, Call Detail Record analysis, ETL processes, CRM integration, Unix-based environments, and legacy-to-modern system transitions. I translate complex technical and business requirements into dependable solutions that improve accuracy, performance, and operational continuity.

I’ve partnered with business leaders, IT teams, engineering groups, finance stakeholders, and external vendors to deliver practical outcomes in demanding production environments. My approach combines disciplined analysis, collaborative leadership, and a consistent focus on service reliability and customer experience.

Based in Puerto Rico and bilingual in English and Spanish, I offer organizations a rare blend of telecom domain expertise, systems thinking, vendor coordination, and hands-on delivery experience.
