Startups and SMBs needing to augment an existing team with one or two specific skill sets.
Companies needing to build a new product or manage a significant feature stream without hiring an entire in-house team.
Projects with clearly defined requirements and deliverables, such as an MVP, a specific feature build, or a Rails version upgrade.
A US-based PropTech startup secured seed funding to build a SaaS platform for commercial real estate management. Their small in-house team lacked the bandwidth to develop the complex features required to compete, and they were facing pressure from investors to launch an MVP within six months.
The client needed to build a feature-rich SaaS MVP quickly to secure the next round of funding. They struggled to find affordable, senior-level RoR talent locally and were losing valuable time in a competitive market.
We deployed a dedicated 'Ruby on Rails SaaS Scale Pod' consisting of two senior RoR developers, a QA engineer, and a part-time UI/UX designer. The team integrated directly into the client's Slack and Jira, operating as a seamless extension of their in-house staff. Our developers architected a multi-tenant application using modern RoR practices, focusing on rapid, test-driven feature delivery. They built out the core property and lease management modules, integrated with Stripe for subscriptions, and developed a robust API for a future mobile app.
"We were burning through our runway with local hiring attempts. Developers.dev gave us a full, dedicated Ruby on Rails team in under two weeks. They didn't just write code; they challenged our assumptions and helped us build a better product. We launched our MVP two months ahead of schedule."
A popular online fashion retailer with over 1 million monthly visitors was experiencing significant performance issues with their aging Ruby on Rails 4 application. Slow page load times were leading to high cart abandonment rates and declining search engine rankings, directly impacting revenue.
The client's monolithic RoR application was plagued by slow database queries, inefficient background jobs, and unoptimized frontend assets. Their in-house team was constantly firefighting and lacked the specialized expertise for deep performance optimization.
We assigned two of our top RoR performance experts. They began with a comprehensive audit using tools like New Relic and Skylight to identify the worst bottlenecks. Their solution involved several key actions: refactoring N+1 queries and adding appropriate database indexes; moving non-critical tasks to asynchronous background jobs with Sidekiq; implementing a caching strategy with Redis for frequently accessed data; and optimizing frontend assets through compression and a CDN.
"Our site was grinding to a halt during peak sales. The team from Developers.dev were like surgeons. They identified and fixed deep-seated performance issues we'd been chasing for years. Our conversion rate jumped almost immediately after they deployed their fixes."
A mid-sized enterprise providing lending services was running their core operations on a brittle, decade-old PHP system. The system was difficult to maintain, lacked modern security features, and was becoming a major compliance risk. They needed to migrate to a modern, secure, and auditable platform without disrupting daily operations.
The client's legacy PHP application was a black box of technical debt. It posed a significant security risk, was failing to meet new regulatory compliance standards, and was hindering the company's ability to launch new financial products.
We assembled a 'FinTech Mobile Pod' with expertise in both Ruby on Rails and secure software development. The project was executed in three phases. Phase 1 involved a deep dive into the legacy system to document all business logic and data structures. In Phase 2, our team built the new RoR application from scratch, focusing on a service-oriented architecture, comprehensive test coverage, and implementing robust security measures like data encryption and detailed audit trails. Phase 3 was the live migration, executed over a weekend using a parallel run strategy to ensure data integrity and a seamless switchover.
"The thought of migrating our core system was terrifying. Developers.dev presented a meticulous, phased plan that gave us confidence. Their Ruby on Rails developers were experts in security and compliance, and the final platform passed our security audits with flying colors. It was a game-changer for our business."
Our 'AI-Enabler' policy is a core differentiator. We don't just give our developers access to AI; we train them in a governed, enterprise-safe framework to amplify their skills. This is how our Ruby developers deliver more value.
Our developers use tools like GitHub Copilot to write boilerplate code, generate complex algorithms, and create RSpec tests faster, allowing them to focus on high-value business logic.
Leveraging AI, our developers can identify code smells, find the root cause of bugs more quickly, and get intelligent suggestions for refactoring code to improve performance and maintainability.
AI tools help automatically generate and maintain documentation for APIs and complex methods, ensuring your codebase remains understandable and easy for new team members to onboard.
Within our secure framework, AI agents continuously scan code for potential security vulnerabilities (like SQL injection or XSS), ensuring your application is secure from the first line of code.
