I've managed all aspects of technology which helps me get up to speed quickly on projects. I'm frequently called in on existing projects and have to figure out what's what. (Most documentation is non-existent or lousy.) I help non-technical product owners and stakeholders make technical decisions about their applications and "translate" for their developer(s). I'm a business owner and spent many years implementing accounting software, so I'm comfortable with the "business side" of applications (electronic payments, SEO, marketing, etc.) I currently manage several SAAS applications hosted in Azure and AWS. I specialize in DevOps, Cloud hosting and Authentication/Authorization (OIDC/OAuth/SSO). I've been working in software development for over 30 years, primarily with Microsoft tools (C#, SQL Server, ASP.Net, SQL Server, Entity Framework, etc.). Over the last decade, I've also work with Angular (a lot), React, PHP and Python. I have published mobile apps for both Android and iOS.
