Senior Fintech Developer — Deploy White-Label Banking Platform on AWS & Integrate Banking Provider

We have a complete, audited white-label banking and payments platform (NestJS backend, React/Vite frontend, PostgreSQL, Docker Compose) that needs deploying to a production-ready AWS environment and connecting to our selected banking providers. This is not a build from scratch. The codebase is complete with deployment documentation. Your job is deployment, provider integration, testing and handover. What you will do: Deploy the full Docker Compose stack (API, Dashboard Backend, Dashboard Frontend, PostgreSQL) to AWS Provision and configure AWS infrastructure: EC2 or ECS/Fargate, RDS (PostgreSQL), S3, IAM roles Replace local-dev mocks with production services (real S3, Resend for email, production secrets) Configure and test existing API integrations with banking partners (Bridge.xyz, RouteFusion, BlindPay) Integrate one additional banking provider (Kira — FBO banking with SWIFT) into the existing codebase Set up HTTPS, DNS, CORS and domain routing Implement Auth0 or JWT-based authentication with 2FA (TOTP) in a production context Run end-to-end verification: health checks, test accounts, compliance gate, KYC onboarding flow, and a live transfer test Set up staging and production environments with logging, backups and monitoring Document the production environment and hand over with clear runbooks Requirements: Strong experience with NestJS or Node.js/TypeScript backends React frontend experience (Vite-based SPA preferred) PostgreSQL + TypeORM (migrations, schema, debugging) Docker & Docker Compose — multi-container orchestration AWS — compute (EC2/ECS), RDS, S3, IAM, networking basics REST API integration and webhook handling JWT / Auth0 / 2FA security implementation Fintech, banking or payments platform experience Nice to have: Experience with BaaS providers (Bridge.xyz, Plaid, RouteFusion, Kira or similar) KYC/KYB and virtual account workflow experience Transaction reconciliation and idempotency CI/CD pipeline setup This starts as a project engagement (deployment through to go-live) with scope to transition to a retained monthly role for ongoing maintenance, feature development and new provider integrations. Remote — UK or compatible timezone overlap preferred. Screening questions: Have you previously deployed a NestJS application to AWS in a production environment? Briefly describe. Have you integrated a banking, payments or fintech API (not just Stripe checkout — we mean account creation, virtual accounts, KYC, transfers)? Please describe. What is your experience with Docker Compose for multi-service deployments? What is your availability and preferred engagement model (hourly vs fixed)?
