Do you have experience rewriting legacy products?

Yes, I have experience rewriting legacy products. Usually, this process begins with analyzing the existing code and architecture, identifying bottlenecks and issues. Then, I develop a phased refactoring or full migration plan, aiming to minimize risks and preserve business logic.

For example, in one project, I rewrote an outdated Java application, splitting the monolith into modules and implementing modern frameworks. This improved scalability and simplified maintenance. An important aspect was test coverage and gradual implementation of changes to avoid disrupting the system's operation.
