order without a rewrite

Legacy code
refactoring.

I bring legacy code back in order: remove duplication and workarounds, improve architectural structure, and reduce technical debt — while preserving the system's current behavior.

Legacy code doesn't have to be rewritten from scratch — it's usually more cost-effective to clean it up carefully. I refactor in small, safe steps so each stage can be verified and regression risk stays minimal.

01 / How I Refactor

How I refactor

Audit and plan

I find the problem areas, assess risks, and map out the order of changes — most painful first, cosmetic last.

Safe steps

I change code in small increments with behavior verification so nothing breaks in production.

Structure and readability

I eliminate duplication, distribute responsibilities across layers, and align naming and style.

Tests for critical logic

I cover critical logic with tests to lock in behavior and make future changes safer.

FAQ

Частые вопросы

Will refactoring break the project?
Refactoring by definition doesn't change behavior. I work in small steps, verify each stage, and where needed I add test coverage first to lock in the current logic.
