Cybersecurity · Identity & Access · Health IT
John Patsias
I keep the right people connected to the right systems, and keep everyone else out. 10+ years in healthcare IT: credentialing for 13,000+ providers, every CMS submission for an ACO, HIPAA risk assessments, and the databases behind it all. Now with a B.S. in Cybersecurity and ISC2 / CompTIA credentials to match.
What I do
Three ways I can help your team
Identity & access security
User provisioning and offboarding, role-based permissions, Active Directory, and HIPAA security risk assessments. I moved a small business off shared local admin accounts onto a managed domain with least-privilege access.
Health IT & provider data
Provider credentialing against NPPES/NPI and Medicare PECOS, CMS submissions, and Medicare data analysis. I automated the manual credentialing reports and built my own search tool on CMS data.
Systems & database admin
SQL databases, CRM administration (Sage ACT!), Windows Server, virtual machines, patching and backups, plus QuickBooks integrations, and training the people who use it all.
Selected projects
Things I've built
Real tools for real problems. Some were built with AI-assisted coding; the design, data model, security decisions and testing are mine.
Provider Credentialing Search
CMS NPPES/NPI and PECOS data combined in one SQL database, with a search that checks identity, specialty and Medicare enrollment in one step.
