At Syncro, I built full-stack billing integrations for 5+ vendors, created a repeatable onboarding pattern, and owned the SKU Catalog from technical spike through delivery. I also redesigned usage-data storage, resolved billing defects that caused revenue leakage, and improved RMM and ticketing capabilities.

I've spent 10+ years building SaaS and web systems across Syncro, Hyly.AI, D.W. Morgan, and Acestar Solutions. My work includes extracting file-ingestion microservices from monoliths, integrating APIs, optimizing high-load production systems, and building internal hardware monitoring tools.
