What Makes Our Ruby on Rails Developers Reliable

Clients trust KPS because we define expectations upfront, match engineers to the real needs of the project, and stay engaged after the start. Our Rails developers follow a clear development process and keep work transparent, so delivery stays consistent, and you stay in control of deadlines.

Our Process

You will follow a clear hiring process at KPS to hire Ruby on Rails developers who match your project requirements and team setup. We focus on developers who can work in real delivery conditions and integrate smoothly into your workflow.

Step 1: Kick-off Call

Clarify your business goals and expectations for the next few months. Agree on scope, priorities, ownership, and measurable KPIs, plus the skill level and time zone overlap you need.

Step 2: Sourcing

Our staffing team selects Ruby on Rails developers who match your industry and stack - Rails applications, API development, integrations, performance optimization, or maintenance.

Step 3: Initial HR Interview

Recruiters assess communication skills, responsibility, time zone compatibility, and the ability to collaborate effectively with other team members.

Step 4: Tech Interview

Each candidate completes tasks based on Rails scenarios. Technical specialists or CTOs test their knowledge of the basics of the Ruby programming language, Rails conventions, code maintenance practices, and real-world experience with version control and testing systems.

Step 5: Client Interview

You meet with the shortlisted Rails developers and ask questions about your architecture, database management, CI/CD, and delivery expectations.

Step 6: Offer

HR department coordinates everything related to the offer: paperwork, NDA agreements, start date, onboarding plan, and alignment of tools and working methods.

Step 7: Retention

Once your partnership with KPS starts, we continue to be involved in the process to ensure the stability of supply.

Why Work with Us

We don't just help you hire Ruby on Rails developers. We provide engineers who understand Rails architecture, delivery risks, and the impact of code changes on the product.

Risk-aware Delivery

Developers flag risky changes early, think through their impact on the Rails applications, and prevent regressions before they hit production.

Strong Collaboration Skills

Our Ruby developers work closely with your team: other developers, PMs, and designers. They clarify requirements, ask the right questions, and report obstacles when needed.

Process Flexibility

Ruby engineers can follow your current workflow (Jira, Linear, Asana, Notion) and fit into your version control systems (Git), PR rules, and release cadence without imposing a new process.

Quality-focused Engineering

Ruby developers write tests using RSpec, keep continuous integration checks clean, and deliver maintainable code that is easy for other team members to review.

Our Services

Whether you are building a new product on Ruby on Rails as a full-stack framework or scaling an existing Rails codebase, including full-stack Ruby work, we are here to help.

Scalable Web Applications

Build and maintain Rails applications with a clear structure and easily maintainable code to keep your product stable as it grows.

API Development & Integration

Provide REST APIs and connect third-party services such as CRM, analytics, email tools, and social media platforms without disrupting core processes.

E-commerce Development

Implement order placement, shopping carts, payments, and secure transactions in Ruby on Rails for reliable web development.

Frontend Integration

Connect Rails to React or Vue to create modern web interfaces based on the stable Rails backend.

Authentication and Authorization

Set up secure login, roles, and permissions using proven Rails approaches (including Devise, if appropriate).

Database Management

Sensitive data management and optimization using Active Record and PostgreSQL/MySQL, including migrations and efficient queries in database management systems.

Performance Optimization & Caching

Increase speed and reduce server load by configuring requests and caching (Redis/Memcached) and targeting performance optimization.

Testing, CI/CD, and Deployment

Automate testing with RSpec/Capybara, maintain continuous integration, and deliver securely with Docker/Heroku/Capistrano.

Additional Services

We can also help you hire front-end developers, DevOps specialists, and quality assurance engineers to keep your Rails work running smoothly from start to finish.
