Secure Backend Architecture Development

I need an experienced full-stack engineer who can give special attention to the backend of my platform and raise its security posture across the board. The frontend is in decent shape, but the core services, data layer, and deployment pipeline all need a careful redesign so that every request, record, and secret is handled with industry-grade protection. Here is the outcome I’m after: • A fresh backend architecture that scales cleanly and is resilient against common threat vectors. • End-to-end authentication and authorization flows, encrypted at rest and in transit. • Well-structured APIs with input validation, rate limiting, detailed logging, and automated tests. • Infrastructure-as-code or container scripts so I can spin up identical, hardened environments in staging and production. • A concise security report summarising what was done, why it matters, and any next steps. I’m flexible on language and framework; what matters is choosing the most sensible stack for long-term maintainability and security. If you have a track record of backend hardening, threat modelling, or compliance-driven development, I’d love to review examples of your past work and talk through an approach that fits my goals.
