About this gig

Need a complete web system not just a website, but a real working tool your team can use?


I will build your web application with user authentication, database, and a full admin panel using React and Supabase.


What I build:

- User registration, login, and permission control

- CRUD systems manage clients, products, orders, records

- Admin dashboards with filters and reports

- Payment integration (Stripe, Mercado Pago, PIX)

- Internal CRM and business management tools

- SaaS platforms from scratch


My portfolio: orcamentomarceneiro.com.br a production SaaS built from zero. React frontend, Supabase backend, Mercado Pago payments with PIX and credit card, affiliate system with commissions, and a full admin panel. Real users, real payments, live today.


What you get:

- Organized database with proper structure

- Secure authentication

- Admin panel to manage everything

- Deployed and ready to use

- Clear communication throughout


Tell me what your system needs to do and I will show you how I would build it.
