Client's Testimonial

Developers.dev didn't just fix our performance issues; they gave us a scalable foundation for the next five years of our growth. Their RoR architects are some of the best I've ever worked with. The project was a massive success, and our platform is now faster and more stable than ever.

Client Introduction

Our client is a US-based, venture-backed MarTech company providing an AI-powered analytics platform for digital marketers. When they approached us, they had achieved product-market fit and were experiencing explosive user growth. Their initial Ruby on Rails application, built for speed, was struggling to handle the load, leading to performance issues and concerns about future scalability. They needed a technology partner who could not only stabilize their current platform but also re-architect it for long-term, sustainable growth without disrupting their existing customer base. Their goal was to scale from 100,000 to over 1 million active users within 18 months.

Problem

The client's RoR application suffered from severe performance bottlenecks, frequent downtime during peak loads, and a monolithic architecture that made deploying new features slow and risky. Their technical debt was increasing, and their small in-house team was overwhelmed with firefighting, unable to focus on innovation.

Key Challenges

Performance Bottlenecks

Slow database queries and inefficient background job processing caused page load times to exceed 10 seconds.

Scalability Limits

The monolithic architecture couldn't scale horizontally to meet user demand.

Slow Development Cycles

A lack of automated testing and a complex codebase meant new feature releases took months.

Zero-Downtime Requirement

The re-architecture had to be performed on a live system with thousands of active customers.

Our Solution

We deployed a dedicated "Ruby on Rails SaaS Scale Pod" consisting of two senior RoR developers, a database specialist, a DevOps engineer, and a QA automation expert. Our solution was a phased approach focused on stabilization, optimization, and modernization.

🔍 Performance Audit & Optimization

We used performance monitoring tools to identify and refactor the top 10 slowest database queries and optimized background job processing with a fine-tuned Sidekiq implementation.

🔄 Database Replication

We implemented a read-replica for the PostgreSQL database to offload reporting queries and reduce the load on the primary database.

☁️ Infrastructure Migration to AWS

We containerized the application using Docker and migrated the deployment from Heroku to a scalable AWS infrastructure using ECS and RDS, managed via Terraform.

⚙️ CI/CD Pipeline Implementation

We built a robust CI/CD pipeline with GitHub Actions, enforcing TDD with RSpec and automating the entire testing and deployment process.

Implementation and Execution

Agile Methodology

The project was executed using an Agile Scrum framework with two-week sprints, allowing for continuous feedback and adaptation.

DevOps Pipeline

We established a full CI/CD pipeline using Salesforce DX, ensuring automated testing and reliable deployments.

User-Centric Design

Our UI/UX expert designed custom LWC components that simplified the quoting interface, making it intuitive for the sales team.

Global Rollout

The solution was rolled out in phases, starting with the North American team, followed by EMEA and APAC.

Comprehensive Training

We developed a full training program and documentation to ensure high user adoption from day one.

Post-Launch Support

We provided two months of hyper-care support post-launch to address any issues and ensure a smooth transition.

Positive Outcome

⚡ 90% Reduction in Page Load Time

Average page load times dropped from over 8 seconds to under 800 milliseconds.

📈 10x Scalability

The new AWS infrastructure could handle 10 times the user traffic with auto-scaling, easily supporting their growth to 1 million users.

🚀 75% Faster Deployments

The automated CI/CD pipeline reduced the time to deploy new features from weeks to just a few hours.

✅ Zero Downtime

The entire migration and re-architecture were completed with zero customer-facing downtime.
