Summary
👤
Senior🎓
Top SchoolLarry Greenwald is a seasoned software engineer and controls specialist with over three decades of hands-on experience spanning Windows and Unix administration, PLC and ladder logic programming, and web/database development. He has a strong track record modernizing IT and control environments—from migrating NetWare/SCO Unix to Windows NT/2000 and rolling out ERP systems to building intranet ticketing and asset-tracking apps tied to SQL Server. Currently providing third-level support and scripting automation (AutoIt, shell) for web, SQL and Oracle-based systems at Optum/UnitedHealthcare, he blends systems administration with application development (.NET, VBScript, PHP, JavaScript). His background in electrical engineering and early work in assembly, Pascal and AutoLISP underpin a pragmatic approach to solving integration and reliability challenges across hardware, network, and software stacks. A licensed ham operator (WB0SIO), he brings disciplined troubleshooting and a curiosity for radio and open-source tools like Linux, Apache and MySQL. Colleagues know him for turning legacy complexity into maintainable, documented solutions that improve information flow and business continuity.
