Freelance Ruby on Rails Expertise
Devintech helps companies that need senior Ruby on Rails expertise to reinforce a team, speed up a project or solve complex technical problems.
Based in Paris, working remotely across France.
Reinforcing a Ruby on Rails team
The need for reinforcement often comes up during a growth phase, a major product shift, a migration, or simply when the engineering team is temporarily short on capacity.
Devintech works directly within existing teams on Ruby on Rails development engagements, at a Senior / Staff level of involvement.
The goal isn't just to ship code, but to contribute to technical decisions, code quality and the long-term maintainability of the application.
Engagements built around existing Rails applications
Ruby on Rails development
Building new features, evolving APIs, integrating external services and improving existing Rails applications.
Performance & PostgreSQL
Diagnosing slow queries, optimizing PostgreSQL, reducing N+1 issues, improving background processing and identifying the main points of contention.
Architecture & scalability
Supporting architecture decisions as the application, traffic or team grows: splitting responsibilities, background processing, APIs, events and a scaling strategy.
Migration & modernization
Upgrading Ruby and Rails versions, progressively reducing technical debt, modernizing dependencies and preparing migrations while limiting production risk.
Ruby on Rails audit
A focused review of an application to identify the main risks and areas for improvement in architecture, performance, code quality, database design or maintainability.
When does it make sense to work with Devintech?
Working together is often relevant when a team needs to:
- quickly reinforce its development capacity;
- move forward on something that requires senior Rails expertise;
- take over or modernize a long-running Rails application;
- fix performance issues that have become hard to diagnose;
- prepare a Ruby or Rails migration;
- improve an architecture that has become hard to evolve;
- secure an important phase of growth or technical transformation.
Technical expertise
The approach stays pragmatic: understand what's already there, identify the highest-priority problems, and step in without pushing an unnecessary rewrite or an overly complex architecture.
Expertise that fits into your team
Devintech can work alongside a CTO, an Engineering Manager, or directly with an existing development team.
Depending on the context, the engagement can combine development, code review, technical design, production troubleshooting and support on architecture decisions.
The way of working adapts to the organization and tools already in place, to keep onboarding time short and get moving quickly on the priorities.
10+ years of Ruby on Rails experience
Devintech draws on more than 10 years of experience with Ruby on Rails applications, from early-stage products to platforms facing real performance, migration, technical debt or scaling challenges.
That experience covers both day-to-day development and problems that call for more architectural perspective.
