ABOUT ME

The "Professor": 40+ years of secure software development

I mentor programmers and development teams. I have the skill set to get you out of any development problem. That includes but not limited to: Java, C#, .NET, JavaScript, TypeScript, Python, Spring, Angular, React, and Agile methodologies. I have a focus on writing "clean code", secure coding, and identity management (SAML 2.0 & OAuth 2.0).

I started working with Java at its release for IBM helping develop their first training programs. I have worked with every Java technology, from AWT through Spring Boot. I have delivered speciality training and mentoring in secure Java to the U.S. Air Force and other entities.

I moved from ASP to .NET and C# immediately when Microsoft released it to compete with the Java environment. I worked on .NET and .NET Core applications integrated with SQL Server. My last big .NET project over 2021 was an integration of .NET Core application with Auth0 using OIDC via OWIN. I have provided mentoring and instruction in secure programming with C# to the U.S. Air Force and other entities.

I have worked with JavaScript since it was Mocha, then LiveScript, and finally JavaScript. I have applied object-oriented principles since it became possible in ECMAScript 5, and even more so when classes appeared in ECMAScript 6. I am comfortable with most popular SPA frameworks including React, Angular, Vue, and Ember.

I started leveraging TypeScript for the better type checking when Microsoft built it on top of ECMAScript in 2012. I am even more comfortable using TypeScript with frameworks like React and Angular than using JavaScript.

As an early member of the Open Worldwide (formally Web) Application Security Project (OWASP) I have worked for years in identifying and solving security issues in Web applications, and applied this to to Java, .NET, JavaScript/TypeScript, Python, and other development environments.

Identity management covers a wide range of sub-topics and I've been involved with most of it. I started with individual systems in RSTS/E and UNIX, helped design and build one of the first distributed (shared) systems for the U.S. Air Force LONEX project, and worked with the beta of DNS. When federated systems such as Kerberos and NIS (formally Yellow Pages) arrived I implemented and leveraged them. After Y2K I implemented SAML and then OAuth, OIDC, and SCIM for federated authentication, authorization, and secure distribution of identity. I am certified with Okta and Auth0 and I work with both companies.

In 1993 at the U.S. Air Force Laboratory we heard about and jumped on a new network standard for sharing documents and information: HTML. With a background in graphics design and publishing as well as programming, HTML evolved right into my skill sets. Now a mature technology, these skills help mentor for good UX and good programming to drive these designs.
