I build and improve production-ready SaaS applications using Next.js, React and TypeScript. This service is ideal if you already have an MVP that needs development work, or if you need a focused SaaS feature built from end to end. I can help with:

New SaaS features and full-stack implementation

React / Next.js frontend development

API and webhook integrations

Stripe checkout, subscriptions and billing flows

Authentication and user account flows

Supabase / PostgreSQL-backed features

Existing application debugging and fixes

Admin dashboards and internal tools

Deployment and production issues

AI API integrations How I work I first understand the existing product and define the smallest reliable implementation path. Then I build, test and verify the complete flow before delivery. The goal is not to rewrite working parts of your product — it is to ship the feature or fix you actually need. Typical deliverables

Working implementation

Responsive UI

Backend/API logic where required

Validation and error handling

Testing of the affected flows

Production-ready code

Deployment support

Short handover summary Message me before purchasing if your project involves a large MVP or multiple major features so we can define the scope clearly.
