We are looking for a highly skilled Full-Stack Developer (CTO/Co-Founder) with strong expertise in React / Next.js, Node.js, PostgreSQL, and AWS. You should be able to structure, optimize, and scale an already existing codebase (around 70% of the product is already developed). You don’t need to start from scratch, but you should be confident in reviewing, refactoring, and extending the platform as needed. Experience in leading dev teams, payment integrations, API connections (KYC, moderation, etc.), and scalable architectures is essential.
