About RubyPlius
RubyPlius is an independent software engineering company registered in Lithuania and founded in 2023. Our team of 15+ engineers has delivered 10+ projects in Ruby on Rails, AI and healthcare software.
Why we specialise
We focus on three areas — Ruby on Rails, applied AI and healthcare software — because depth in a few domains produces better software than breadth across many.
- Ruby on Rails is our core: we build on it, upgrade it and know where it breaks.
- Applied AI extends the products we build with assistants, RAG and document processing.
- Healthcare is where both meet strict data-protection rules, and where careful engineering matters most.
How we make engineering decisions
Six principles guide how we scope, build and hand over software.
Proven technology first
We choose well-supported tools your next team can maintain.
Written over verbal
Scope, decisions and risks are written down and shared.
Small, reversible changes
Frequent small releases are safer than rare big ones.
Data protection by design
Privacy and security are requirements from day one.
Honest estimates
We say what we don't know and update estimates early.
You own the result
Code, documentation and accounts belong to you.
