Concrete results. Real stories.
Each technical debt case study below documents how we helped engineering teams regain control of their software and deliver measurable software refactoring results.
B2B Payment Platform
Fast-growing fintech startup with a legacy platform unable to support the required transaction volume. The engineering team spent 70% of their time managing incidents.
The Challenge
- 8-year PHP monolith with no automated tests
- 40+ production incidents per month
- Risky deployments requiring entire weekends
- Impossible to hire quickly: 6-month onboarding
The Eden Intervention
We worked with the team for 8 months, implementing a strategy of progressive monolith decomposition into independent services, starting from the most critical areas.
- Extraction of 3 critical microservices
- Full CI/CD implementation
- 85% test coverage on new modules
- Complete architectural documentation

Enterprise Management Software
SaaS company with 200+ enterprise clients whose codebase had become a classic legacy modernization case study: feature releases consistently broke existing client customizations.
The Challenge
- Codebase with 15+ forks for different clients
- Impossible to release universal updates
- Team fragmented on maintenance instead of innovation
- Rising churn rate due to lack of new features
The Eden Intervention
We designed and implemented a plugin architecture system that allows customizations without forks, unifying the codebase while maintaining flexibility for each client.
- New modular plugin architecture
- Migration of 200+ clients with no downtime
- Feature flags system for gradual rollouts
- Internal API for secure extensions

Common patterns in our interventions
Every project is different, but some patterns repeat. Here is what we have learned.
Technical debt is always more expensive than you think
The hidden costs (team slowdown, recurring bugs, hiring difficulties) often exceed the cost of a software refactoring intervention.
Incremental beats revolutionary
Complete rewrites rarely work. Incremental, targeted interventions deliver safer and more predictable results.
The internal team is fundamental
The best interventions are done WITH the team, not INSTEAD of the team. Knowledge transfer is part of the success.
Every project is different
But our approach remains constant: rigorous analysis, measured intervention, demonstrable results. Every refactoring success story starts with a clear diagnosis.
Total transparency
Weekly progress reports, shared metrics, no surprises.
Collaboration
We work with your team, not instead of your team. Skills transfer included.
Guaranteed results
We define success KPIs together. If we do not reach them, we review the agreement.
