About

Professional Ruby developer with more than a decade of experience.

I work with Ruby web applications at any stage, whether that means building something new, extending an existing system, or keeping it running smoothly. I prefer practical solutions over clever ones, and aim to leave codebases cleaner and more maintainable than I found them.

Primarily Rails, but comfortable with other Ruby stacks. Based in Sweden, working remotely with clients in Europe and beyond.

Introducing Veri – Minimal Cookie-Based Authentication for Rails

June 25, 2025

https://github.com/enjaku4/veri

Veri is a new minimalistic authentication framework for Rails built around granular session management. Unlike full-stack solutions, Veri doesn’t impose business logic or provide pre-built views and controllers. It focuses on secure authentication primitives with detailed session control and gives you the building blocks for custom authentication flows.

Key features:

  • Database-stored sessions with detailed tracking info
  • Sessions can be listed and terminated selectively
  • Built-in user impersonation for admin features
  • Secure password storage with multiple hashing algorithms
  • Return path handling

It’s functional and ready to try, although still in early development with potential breaking changes before v1.0.
