Enterprise SaaS Platform
Constraints
Could not afford downtime. Had to maintain feature velocity during migration. Limited engineering bandwidth for refactoring.
The Problem
A 6-year-old monolithic Rails application was slowing the team down. Deployment took 2 hours and often failed. The codebase was brittle—every change risked breaking something else. Customer churn was increasing due to reliability issues, and the team could not ship features fast enough to compete.
Our Approach
Started with a technical debt audit to identify the highest-impact areas. Broke the monolith into services incrementally, starting with the most problematic modules. Set up CI/CD pipelines with automated testing and blue-green deployments. Implemented comprehensive monitoring with Datadog. Worked alongside their team, reviewing code and pairing on complex migrations.
Outcome
Deployment time dropped from 2 hours to 15 minutes. Customer-reported incidents decreased by 70%. The team started shipping features 3x faster. Platform uptime improved from 97.2% to 99.9%. Engineering morale improved significantly.
