You will get Secure Next.js + Express Auth & RBAC with Supabase
Project details
I will configure and adapt a tested Next.js + Express authentication and RBAC foundation for your application. The stack uses TypeScript, Supabase Auth/PostgreSQL, Prisma, RLS, HttpOnly cookie sessions, CSRF protection, Google OAuth, email confirmation, password recovery, profile and admin user management, audit events, OpenAPI, GitHub Actions CI, and Dockerized client/API modules.
The delivery is adapted to your project: Supabase configuration, application URLs, OAuth callbacks, SMTP for auth emails, environment settings, and compatible user roles. The current foundation is validated by 675 automated tests and end-to-end scenarios across the API, database/RLS/security layer, client, and Playwright browser flows.
You receive clean project repositories, complete delivered source code, validation, and handoff documentation. Multi-tenancy, major authorization redesign, additional OAuth providers, new business modules, and production deployment are separately scoped.

About Mihai
Full-Stack Engineer | React, Next.js, Spring Boot, Express.js
Cluj-Napoca, Romania - 1:07 am local time
I can handle the full development process, from requirements and system architecture through frontend and backend implementation, database design, REST APIs, third-party integrations, testing, and deployment.
I can help you with:
• Business websites and content platforms built with React and Next.js
• Full-stack web applications and SaaS products
• Responsive interfaces, forms, dashboards, and business workflows
• Express.js and Spring Boot backend services
• REST API design and implementation
• Authentication, authorization, roles, and permissions
• PostgreSQL and MongoDB data modeling and integration
• Third-party API and service integrations
• Technical SEO for Next.js websites
• Testing, debugging, and application reliability
• Docker Compose environments and application deployment
My work focuses on clear requirements, practical architecture, maintainable code, and incremental delivery. I communicate assumptions and constraints directly, keep the implementation aligned with the agreed scope, and avoid unnecessary complexity.
I am particularly well suited to business websites, internal tools, workflow-driven applications, SaaS products, and projects that require both frontend and backend ownership.
Share your requirements, current stack, and expected outcome, and I will propose a practical implementation approach.
