Full-Stack Digital Identity Platform

I need a seasoned full-stack developer to build a secure digital identity system that works seamlessly across both web and mobile. Core functionality must include: • Robust user authentication and verification • End-to-end data encryption and overall security hardening • Flexible user-profile management with editable personal data, avatars, and activity logs I expect a clean, scalable codebase, clear API documentation, and a straightforward deployment guide so I can spin up new environments quickly. If you have experience with modern stacks such as Node.js, React / React Native, or comparable frameworks—and can prove past success delivering security-focused applications—let’s talk timelines and milestones.
