I build Next.js applications for products that need a capable interface and a dependable server layer. A public website, authenticated dashboard, and content catalogue have different rendering and caching needs; the architecture should reflect those differences from the first working version.
Work can begin with a new product, an existing React application, or a Next.js codebase with performance and maintenance problems. I connect interface work with authentication, API contracts, deployment configuration, and measurable acceptance criteria so a feature can be reviewed as a complete user journey.
When this service fits
Useful for SaaS interfaces, content-driven websites, customer portals, and teams that need a React developer who can also work through server-side decisions. Share the critical routes and current stack to establish the right scope.
App Router and component boundaries
I organize routes, layouts, loading states, and error recovery around product features. Server and client components have explicit responsibilities, keeping interactive code where it is needed and preventing sensitive server configuration from reaching the browser. Existing conventions matter more than introducing an unnecessary abstraction.
Data, authentication, and forms
A complete feature includes validation, authorization, persistence, and understandable feedback. I define where data is fetched and changed, how access is checked, and which states a form must represent. Cache behavior and revalidation are reviewed alongside those mutations to avoid showing stale or account-inappropriate information.
Technical SEO and performance
Public pages need consistent metadata, canonical URLs, crawlable navigation, and sensible image delivery. I examine the rendered page and loading behavior before choosing optimizations. Private application routes need a separate indexing policy. Performance changes should target a demonstrated bottleneck such as excessive client JavaScript, slow queries, or a costly image.
Migration and production delivery
For existing applications, I prefer an incremental route or feature migration with a clear rollback point. Delivery includes environment configuration, build verification, error visibility, and the operational steps required to run the result. A documented handover makes the application easier for your team to change after launch.
What the handover includes
- Implemented routes and components with agreed loading, empty, and error states.
- Documented data boundaries, access checks, and environment requirements.
- Relevant verification and deployment or migration instructions.
Development process
Review the product routes
Identify public and private pages, the primary user task, existing APIs, and deployment constraints.
Build one complete feature
Connect the UI to validation, permissions, and persistence before expanding the same pattern.
Verify rendered behavior
Review navigation, cache updates, metadata, errors, and the critical workflow on relevant screen sizes.
Deliver with operational context
Record configuration, release steps, known constraints, and the next decisions your team will own.
Relevant portfolio projects
These pages document the products and available project details. They provide context for related workflows; implementation stacks and responsibilities are stated only where documented.

Frequently asked questions
Can you work in an existing Next.js application?
Yes. I first review the version, route structure, deployment environment, and a representative feature. We can then scope a feature, an architectural improvement, or an incremental migration without assuming a full rewrite.
Is Next.js the right choice for every website?
The choice depends on content, interactivity, authentication, and hosting requirements. I can review those constraints before committing to a stack. A simple site and an authenticated product can need very different solutions.
Can you handle both frontend and backend work?
Yes. The scope can include React interfaces, server-side application logic, database integration, API endpoints, and deployment preparation. For a larger system, we define ownership and boundaries with your existing team first.
