Legacy Code Rewrite and Modernization

Migrate from legacy monolith to modern architecture with zero downtime and full test coverage.

Zero Downtime

Strangler Fig pattern and feature flags ensure your users never experience a service interruption. Old and new code run in parallel during the transition.

Monolith to Microservices

Decompose your backend into scalable, domain-driven services. Each service is independently deployable, testable, and maintainable.

React + Golang Migration

Modern frontend with Next.js SSR and high-performance Go backend. Comprehensive test coverage ensures nothing breaks during migration.
