Build Dual-Mode Freelance Platform

I’m ready to launch an online marketplace dedicated to design, writing, and marketing talent. The site has to support both traditional job posts—where clients list projects and freelancers send proposals—and a direct-hire path so clients can book professionals instantly. For the MVP I need: • Robust user profiles for both freelancers and clients, complete with portfolio sections. • A job posting workflow that lets clients publish requirements and receive/manage proposals. • A direct-hire flow with a “Hire Now” button visible on every qualified profile. Please architect the full stack, design an intuitive, mobile-first interface, and deliver clean, well-documented code so future enhancements—messaging, reviews, payment escrow—can slot in smoothly. If you’ve built marketplaces or gig platforms before, tell me which frameworks and tools you’d use and share relevant links or demos.
