About

I’m a software engineer and technical leader with a background in .NET platforms, data integrations, and engineering leadership. I enjoy turning complex systems into software that teams can understand, maintain, and build on.

Today, I lead a team of six AI engineers at Cendyn, working toward the company’s technical and product roadmap. Our work spans AI infrastructure, governance, developer tools, and security assessment platforms.

Before moving into AI engineering leadership, I modernized hospitality integrations and built a platform for migrating client data from a legacy CRM into New CRM. Earlier, I worked on enterprise software at Intapp and public-sector systems at the Dominican Republic Immigration Office.

CRM migration platform

Platform development at Cendyn, 2026

Built an ETL platform to move client data from a legacy CRM into CCRM. It connects to multiple SQL Server instances and databases, transforms records into the destination format, and delivers them over HTTP.

Architecture and reliability
  • An orchestrator-based backend coordinates the migration process.
  • Adapters for each module or entity make behavior reusable and adaptable.
  • Retry mechanisms support reliable execution.
  • Tracing, logging, and auditing make migration activity observable and easier to troubleshoot.

Worked with the Integrations team to replace legacy codebases with modern .NET microservices, streaming data from external property management systems into internal databases.

Systems and approach

Developed integrations with Oracle OHIP, RMS, Jonas Chorum, Cloudbeds, and SIHOT.

The platform modernization used microservices, event-driven processing, and real-time streaming to connect external PMS systems with internal data stores.
