While shopping for a house, I needed an amortization calculator that was more helpful to my budget than what I was finding online. So, I made one. I also took the opportunity to test what kind of CI/CD pipeline--with security tests--can be created (for free) with the built-in tools available on GitHub. The demo is hosted on Heroku via Docker containers.
OWASP Top 10 is considered the "gateway to AppSec", so naturally I'm interested. But quickly I found it confusing to read about generic security vulnerabilities when I was used to code snippets and hands-on examples as a developer. So, I brought the two ideas together: OWASP Top 10 + hands-on code.
