Full-Stack Developer (React/Vite/Tailwind) for AI Platform

I'm building an AI-powered platform in the business and financial analysis space. A lot of it is already built and prepared. I need a developer to review the existing stack and confirm it's the right one, then help make the product commercial-grade and enterprise-ready: hardening, polish, and proper QA. Full details shared with shortlisted applicants. How we'll work: live sessions of 4-5 hours at a time, on a call, screens shared, building and problem-solving together in real time (plus some solo work between sessions). If you prefer fully async solo work, this isn't for you. If you like pairing and thinking out loud, you'll enjoy it. Requirements Strong full-stack experience with shipped products Confident with React, Vite, and Tailwind — and able to give an honest verdict on whether the current stack holds up Experience taking a product from working prototype to commercial, enterprise-ready quality Solid QA skills: testing, catching edge cases, and not calling things done until they are Experience integrating AI models/APIs Startup experience preferred; clear communicator who can push back thoughtfully Available for 4-5 hour live sessions with reasonable overlap with Sydney (AEST) To apply One thing you've built or productionized that you're proud of, with a link Your timezone and when you can realistically do 4-5 hour sessions overlapping Sydney Start your proposal with the word "velocity" — proposals without it get declined
