Software engineering services
RubyPlius offers three services: Ruby on Rails development and upgrades, AI implementation, and healthcare software. Each follows the same path — define the problem, agree on a written scope, deliver in short, reviewable iterations.
01 · Ruby on Rails
Ruby on Rails development & upgrades
We build new Rails products, extend existing codebases and upgrade Rails and Ruby versions without freezing feature work.
Problem
- Rails or Ruby out of security support
- Slow pages and background jobs
- Few tests, risky releases
Scope
- Upgrade path, one minor version at a time
- Performance and test-coverage targets
- New features alongside the upgrade
Delivery
- Dual-boot CI on every pull request
- Small releases to production
- Upgrade report and runbook
02 · AI
AI implementation
We implement AI assistants, retrieval-augmented generation (RAG) and document processing on your own data, measured against quality metrics agreed up front.
Problem
- Answers buried in documents and tickets
- Manual data entry from PDFs and scans
- Pilots that never reached production
Scope
- One measurable use case
- Data sources, access rights, guardrails
- Evaluation set and quality metrics
Delivery
- RAG assistant or extraction pipeline
- Evaluation report against the metrics
- Monitoring, cost tracking, human review
03 · Healthcare
Healthcare software
We build patient and clinic platforms, HL7 FHIR integrations and medical AI, designed in line with GDPR and HIPAA from the first sprint.
GDPRHIPAAHL7 FHIR R4
Problem
- Clinical data spread across systems
- Manual scheduling, intake and reporting
- Compliance slowing delivery down
Scope
- FHIR resources and data flows
- GDPR / HIPAA controls mapped to features
- Roles, consent and audit requirements
Delivery
- Patient or clinic platform, integrations
- Access logging and encryption by default
- Documentation for your compliance team
Engagement models

- Best for
- Ongoing product work
- Pricing
- Monthly, per engineer
Technical audit
A short review of a codebase, upgrade path or AI idea, with a written recommendation.

FAQ
Questions about our services
The most common questions before an engagement starts.
Which service should I choose?
Start from the problem: an ageing or slow Rails application points to Rails development and upgrades; manual work around documents or knowledge points to AI implementation; anything that stores or exchanges patient data points to healthcare software. If unsure, a technical audit answers the question.
Can one project combine several services?
Yes. A common combination is a Rails upgrade followed by AI features on the same codebase, or a healthcare platform with FHIR integrations and document processing.
Do you work with our existing team?
Yes. We work in your repository and tools, follow your conventions, and review code with your engineers.
Who owns the code?
You do. Intellectual property in the code we write for you transfers to you under the contract.
Not sure which service fits?
Describe the problem and we will suggest the shortest path to a solution.
