Senior Full-Stack Developer Needed for Secure Video Licensing SaaS Platform

I am looking for an experienced Senior Full-Stack Developer to build a custom SaaS platform for a professional video licensing business. This is NOT a WordPress, Shopify, Wix, or template website. It is a secure web application that allows videographers to upload professional weather footage while approved media organizations can securely preview, license, and download original videos. The platform architecture, security requirements, workflows, and feature specifications have already been documented. I am looking for an experienced developer who can implement the platform while providing professional technical recommendations where appropriate. Preferred Technology Stack * Next.js * React * TypeScript * Node.js * Supabase (Authentication, PostgreSQL, Row Level Security) * REST APIs * Bunny Storage * Bunny Stream * FFmpeg * Cloudflare * GitHub Main Features * Public website * Secure authentication * Invitation-only user accounts * Role-based permissions * Secure video uploads * Automated video processing using FFmpeg * Watermarked preview generation * Secure original file storage * Video licensing workflow * Secure download authorization * Organization-based pricing * Invoice management * Audit logs * Responsive design for desktop and mobile Security, scalability, and maintainability are top priorities. What I’m Looking For I’m looking for a developer who has experience building production SaaS applications and can demonstrate knowledge of: * Next.js * React * TypeScript * Supabase * PostgreSQL * Row Level Security (RLS) * Authentication and authorization * Large file uploads * Video processing * Secure file storage * Clean, maintainable code * Testing and documentation If your primary experience is WordPress or simple business websites, this project is probably not the right fit. Project Documentation The complete Build Specification, Security Requirements, and Pre-Launch Checklist will be shared with shortlisted candidates after the initial interview. Ownership All source code, documentation, infrastructure, and deliverables created for this project will become my property upon payment. All repositories and cloud services will remain under my ownership. Please Include in Your Proposal * Examples of production SaaS applications you personally built. * Your experience with Next.js and Supabase. * Your experience implementing Row Level Security. * Experience with FFmpeg or similar video processing tools. * Experience with secure file storage and download authorization. * A brief explanation of how you would approach this project. This project will use milestone-based payments over approximately 1–3 months. I am looking for quality, security, and long-term maintainability rather than simply the lowest price. Shortlisted candidates will be invited to a video interview before a final hiring decision is made.
