Code Refactoring & Project Modernization
We modernize outdated systems without rewriting them from scratch. We clean up the architecture, update technologies, and remove technical debt — quickly and safely.

Legacy code costs
more than you think
Unmaintained code slows development, generates bugs, and makes onboarding difficult. And every month without refactoring deepens the problem.
New features take
longer and longer
Every change in legacy code requires understanding undocumented dependencies. Developers spend 70% of their time understanding the code, 30% writing new code.
Bugs come back
after every change
No tests and tangled architecture is a recipe for regressions. You fix one bug, two new ones appear. Without refactoring, this cycle continues indefinitely.
New developers
need months
No documentation, hundreds of files without structure, magic in configuration — a new developer only becomes productive after 3–6 months in a legacy project.

Modernization tailored
to project scale
From code cleanup through architecture modernization to full technical transformation. Every phase safe, tested, and deployed incrementally.
Code
refactoring
We clean up code without changing functionality — remove dead code, simplify complex methods, introduce tests and a clear module structure.
- Analysis and audit of current code state
- Automated tests before every change
- Dead code and duplicate removal
- Simplification of 200+ line methods
Architecture
modernization
Code refactoring plus structure modernization — layer separation, module extraction, framework updates. System ready for further development.
- Everything from code refactoring
- Separation of business logic and infrastructure
- Framework updates (Strangler Fig Pattern)
- Test coverage >80% on completion
- Architecture documentation and ADRs
Full modernization
with migration
Comprehensive transformation — refactoring, architecture modernization, and cloud or containerization preparation. Opens the door to Kubernetes and modern DevOps.
- Everything from architecture modernization
- Containerization (Docker) and CI/CD pipeline
- Kubernetes or serverless preparation
- Knowledge transfer and onboarding documentation
- 4 weeks of post-project support
How do we refactor?
Tests first, then changes —
every modification confirmed by green tests.
Audit and plan
We analyze the code, identify the biggest risks, and create a refactoring roadmap with priorities and estimates.
Tests as a safety net
Before every refactoring, we write tests (unit, integration, e2e) that confirm the behavior doesn't change — even if the implementation does.
Incremental refactoring
We introduce changes in small steps — Strangler Fig Pattern for larger modules. New code gradually replaces old, every step through CI/CD.
Deployment and verification
Every change through the CI/CD pipeline. We monitor metrics after deployment and respond to anomalies. Final report: test coverage, complexity, deployment time.
What changes
after refactoring?
Faster development, fewer bugs
Clean code with tests means faster feature delivery. Teams save 30–50% of maintenance time after refactoring — and have fewer production bugs.
Onboarding in weeks, not months
Refactored, documented code is understandable. New members join the project in weeks — they don't need 6 months to discover the magic.
Safe changes with tests
>80% test coverage is a safety net. Every change is automatically verified — regressions caught before production, not after an incident.
Ready for modern technologies
After refactoring it's easier to move to Docker, Kubernetes, microservices, or serverless. Opens the door to the cloud and modern DevOps — without rewriting from scratch.
Have a legacy project that needs modernization?
We'll audit it and show you how to safely refactor the system — without rewriting from scratch, without downtime, with measurable progress every sprint.
