Refactor Legacy Monolith to Modern React & Go
Transform legacy spaghetti code into a clean, modern microservice stack. Speed up new feature engineering by 3x.
Platform vs our custom development
| Parameter | Legacy Monolith (PHP/ASP.NET) | Our development · React + Go |
|---|---|---|
| Feature Delivery Speed | Weeks / Months | Days |
| Bug Investigation Time | High | Minimal (Type-Safe) |
| Server Resource Consumption | Heavy | 5x - 10x Lower |
What holds your project back
Crushing technical debt
Shipping a small feature takes weeks because the original codebase is brittle and unmaintained.
Hiring bottlenecks
Top engineering talent refuses to work on outdated 10-year-old legacy frameworks.
Outages during traffic spikes
Synchronous legacy architectures crash under concurrent user load.
What you gain after migration
Clean modular architecture
Clear separation of frontend and backend. Fast onboarding for new developers.
High concurrency with Go
Go consumes minimal server memory while easily sustaining thousands of requests/sec.
Type-safe reliability
Strict static typing across TypeScript and Go reduces production bugs to near zero.
Management tools for your team
We agree on the features you need and connect the services you already use.
Modern Backoffice
Clean administrative control panel without cognitive overhead.
Migration process
We verify data and workflows before switching to the new system.
Codebase Audit & Docs
We audit existing business rules and map system boundaries.
Iterative Migration
We migrate services step-by-step without interrupting business ops.
Production Switchover
We launch the upgraded system into live production.
Optional marketing support
Measure your product after migration
Goals, forms, purchases and CRM attribution. Connect the tools your market needs and see the journey from source to result.
What happens to traffic during migration?
Capture the baseline, check redirects and indexing at launch, then monitor changes for 4–8 weeks. Scope is agreed separately.
