CLIENT FEEDBACK
When you hire Ruby on Rails developers, technical skills are only one part of the equation. The other part is how a developer works inside your team: communication, ownership, and the ability to turn requirements into clear delivery steps. 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.

Kevin Hill
Director of Technology & Data Strategy, SuperordinaryI’ve worked with many companies over the years. We’ve never gotten better results for the money we paid.

Mike Dejworek
Founder at RejsespejderI found motivated professionals and good friends. They’re more than just service providers. I can truly trust them, and as I see it, nothing is more important than this.

Rony Keren
CTO, Liquidity CapitalThey care about our success, what we do, and who we are, and the results reflect that. They can deliver on points where I’m not sure other companies could.

Asaf Ashkenazi

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. After you choose the right RoR developer, we support onboarding and align on tools, communication, and "done" criteria, so the start is fast and predictable.
STEP 01:
First, we clarify your business goals and expectations for the next few months. We agree on scope, priorities, ownership, and measurable KPIs, plus the skill level and time zone overlap you need. We also confirm whether the focus is on rapid prototyping or long-term product development.
STEP 02:
Our staffing team selects Ruby on Rails developers who match your industry and stack — Rails applications, API development, integrations, performance optimization, or maintenance. We also take into account your workflow, tools, and team composition.
STEP 03:
Recruiters assess communication skills, responsibility, time zone compatibility, and the ability to collaborate effectively with other team members. This is where we evaluate the practical aspects of collaboration, not just resumes.
STEP 04:
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 05:
You meet with the shortlisted Rails developers and ask questions about your architecture, database management, CI/CD, and delivery expectations. This will help you confirm the candidates' suitability before making a hiring decision.
STEP 06:
HR department coordinates everything related to the offer: paperwork, NDA agreements, start date, onboarding plan, and alignment of tools and working methods. So that your development process remains predictable from Day 1.
STEP 07:
Once your partnership with KPS starts, we continue to be involved in the process to ensure the stability of supply. If priorities change or something isn't working, we help make adjustments in a timely manner. Before it leads to delays or rework.

OUR STRENGTHS
Our goal is not just to fill your vacancy. We focus on keeping your Ruby team productive, stable, and aligned with your delivery plan. Here's what sets the KPS approach apart:
Our recruiters constantly update our network of Ruby developers who work with modern Ruby on Rails stacks, APIs, and Rails production systems, rather than outdated profiles.
We don't just match candidates based on job titles. Our tech leads, together with the recruitment team, analyze your field of activity, project requirements, and current code base to find Rails developers who fit your team's working style.
For complex Rails applications, our senior developers help verify technical depth before you spend time interviewing. For example, when you need to fix performance bottlenecks, run upgrades, or scale the system safely.
Need to scale up for release, add API capacity, or focus on stabilization and maintenance? We can adjust your team composition without long-term commitments.
We continue to work with you after kick-off: checking in, coordinating actions, and quickly making changes if something isn't working, so your development process remains predictable.
You get transparent monthly rates and clear expectations regarding the scope of work, with the option to increase or decrease them as your workload changes.
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.
Developers don't just ship features. They flag risky changes early, think through their impact on the Rails applications, and prevent regressions before they hit production.
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.
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.
Ruby developers write tests using RSpec, keep continuous integration checks clean, and deliver maintainable code that is easy for other team members to revie
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. KPS will help you hire Ruby on Rails developers who support both new feature implementation and long-term maintenance. You will receive stable technical support for back-end development and delivery using clear Git practices in your version control systems without slowing down the implementation of your action plan.
Build and maintain Rails applications with a clear structure and easily maintainable code to keep your product stable as it grows.
Provide REST APIs and connect third-party services such as CRM, analytics, email tools, and social media platforms without disrupting core processes.
Implement order placement, shopping carts, payments, and secure transactions in Ruby on Rails for reliable web development.
Connect Rails to React or Vue to create modern web interfaces based on the stable Rails backend.
