Project fit
For SaaS teams that need modernization without breaking the product users already use.
This page fits SaaS apps that started in React, older Next.js versions, custom routers, or fragile dashboard stacks and now need better routing, metadata, performance, and maintainability.
Scope snapshot
A SaaS migration should be phased, measurable, and easy to roll back if needed.
The safest path maps current routes, auth, data fetching, dashboards, SEO requirements, deployment, and risky pages before moving the app into a cleaner Next.js structure.

Problem
SaaS migrations fail when teams turn modernization into a full rewrite.
A rewrite can hide the original product logic, break dashboards, damage SEO, and delay launches. A better migration preserves what works while replacing fragile routing, metadata, rendering, and structure.
- Routes, metadata, and SEO behavior are inconsistent across the SaaS app
- Dashboard pages are slow or difficult to maintain
- Auth, layout, and data fetching are scattered across components
- Migration scope is unclear and becomes a rewrite
- Deployment and rollback plans are missing

Quality standard
A SaaS migration should improve the product without erasing business logic.
The build should preserve working workflows, document trade-offs, and avoid a blind rewrite that creates new bugs while chasing a new framework version.
- Current routes and user workflows are inventoried first
- SEO metadata and canonical behavior are reviewed
- Auth and protected pages are tested carefully
- Performance issues are addressed with specific fixes, not vague claims
- Deployment and rollback notes are included
- Mobile and desktop content remain equivalent after migration
Process
From audit to handoff.
The engagement starts by mapping the industry workflow, users, data, integrations, risks, and the fastest safe path to a useful production system.
- Audit the existing SaaS app, routes, auth, dashboards, SEO needs, and deployment setup.
- Create a phased migration plan with priorities, risks, stack choices, and test coverage.
- Migrate critical layouts, routes, metadata, dashboards, and data workflows in controlled steps.
- Launch with QA checks, monitoring notes, rollback guidance, and documentation.
