I will build a full stack web app with next js and supabase


About this gig
Full stack developer with hands-on production experience building internal platforms - including systems handling financial and operational data - using Next.js, TypeScript, Node.js and Supabase. I also have an Accounting background, which helps me understand business and financial logic when building dashboards, internal tools and data-heavy applications.
What I can build for you:
- Full stack web applications (Next.js + Supabase/PostgreSQL)
- - Internal dashboards and admin panels
- - REST API integrations (CRMs, ERPs, HubSpot, Monday.com-style tools)
- - PDF generation and automated reports
- - Bug fixes and feature additions to existing Next.js/Node projects
I focus on clean, maintainable code and clear communication throughout the project. Let's talk about what you need before you order, so I can scope it accurately.
