Secure software development with Ruby on Rails

Security decisions become harder to change once an application is in daily use. I develop custom web applications with Ruby on Rails and work on existing codebases, considering security and privacy alongside functionality.

Start with the application’s boundaries

Who uses the application? Which information does it handle? Which actions should each user be able to perform? These questions help define the data model, access controls, and architecture before implementation.

Work on new or existing software

• Design and build a custom Rails web application
• Review architecture and data handling in an existing codebase
• Improve authentication and authorisation
• Make agreed changes with maintainability in mind

Handover matters

The code should remain understandable after the project ends. I document the decisions and explain how the application is deployed and maintained, within the scope we agree. Your team should be able to continue the work.

Discuss your project

Share what the application needs to do, who will use it, and whether there is an existing system. We can establish which parts need development and which security questions need attention first.
