Is there a posibility to transform this personal finance app into julia？
Oxygen, Genie?
I’d suggest using Julia as a compute/analytics backend rather than rewriting Sure entirely in Julia.
A pragmatic approach is to keep the existing Ruby/Rails app as the application layer (accounts, auth, deployment, etc.), and implement any heavy computation in a Julia service (e.g., exposing an API via HTTP.jl / Oxygen.jl) and communicate over HTTP or a queue. You could also go full-stack in Julia with Genie, but that’s a much bigger migration.
That said, for a personal finance app like this, most of the backend work is typically Create, Read, Update, and delete (CRUD) and doesn’t require complex numerical computing. If the goal is simply to run and iterate on the product, Ruby/Rails full stack (the current practice) will likely be simpler and benefit from a much larger ecosystem.
Also, Ruby/Rails has a very mature web development ecosystem and tooling end-to-end: strong conventions for building and structuring web apps, a huge set of production-proven gems, and established solutions for common web concerns. In practice, that maturity usually translates to faster iteration and lower engineering risk for a full-featured web app.
So unless you specifically need Julia’s numerical/optimization strengths (or this is mainly a learning/interest-driven rewrite), a full migration to Julia probably isn’t very cost-effective.
