Modern Secure Fintech Web Platform

I’m building a fully-featured fintech website and need an experienced developer to take it from concept to production. The platform must let end-users create an account, sign in with a traditional email-and-password flow, and then manage their finances through an elegant, mobile-responsive interface. Core modules will include user authentication, personalised dashboards, payment or transaction handling, rich data visualisations, and a lightweight admin panel. Strong application-level security (OWASP best practices, encrypted credentials, rate limiting) is mandatory, as is fast performance on both desktop and mobile. My preferred stack is React or Next.js on the front end, backed by Node.js or Python services that talk to a PostgreSQL database and external payment/banking APIs. I intend to host on AWS or Vercel, so familiarity with CI/CD pipelines, infrastructure-as-code, and automated testing will be valuable. Deliverables • Production-ready source code with clean architecture and comments • Deployed site (test and live environments) behind TLS and WAF • Admin dashboard to manage users, transactions, and settings • Documentation covering API endpoints, environment variables, and deployment steps • Handover session to walk me through setup, security controls, and future scalability options If you have a proven track record launching secure, responsive fintech or SaaS products with the technologies above, I’d love to hear how you would approach this build and a realistic timeline for each milestone.
