Senior Backend Developer at Synqly building Go connectors and OCSF data pipelines across SIEM, EDR, and ITSM platforms.

At Synqly, I build and maintain Multiplex Connectors that help SIEMs, ticketing systems, EDRs, and vulnerability scanners work together without custom point-to-point integrations. I design Go-based connectors and normalize partner data into OCSF using Bloblang.

At Centene, I led a distributed development team, owned solution architecture, and took implementation through to production. Earlier, I built a cloud-based digital-signature solution for the Santa Fe Chamber of Deputies and developed a Flutter app with a Go backend integrating Apple and Google purchase and subscription APIs.
