Legacy Migration to React / Next.js
Modernize the stack without creating vendor dependency.
The real risk of a migration isn't technical — it's ending up with a modern stack only the vendor who wrote it can maintain. My offer inverts that model: I migrate in phases, in your codebase, with reviewed code and documented conventions at every step. By the end, you don't need me anymore. That's the goal.
How it works
- Audit of the existing system + phased migration plan; the legacy system stays live as fallback at every step.
- Phase-by-phase migration, in production, without stopping the business.
- Working in the open: pull requests reviewed with your team, documented architecture conventions.
- Handover: your team ships autonomously.

Custom quote, fixed phases
Each phase: fixed scope, fixed price, verifiable deliverable. Stop at the end of any phase — the system keeps working.
