Secure FinTech App Tutorial | Golang Backend + React Frontend + HTTPS Setup

🌍 Build & Deploy a Real-World Golang FinTech App (with React, HTTPS & Kubernetes) This project walks you through building and deploying a secure FinTech application using Golang (Go) for the backend and React for the frontend. It mimics how real-world money apps work—multi-currency, cross-border payments, email-based transfers, and live currency swaps. It’s fully containerized, deployed to Kubernetes, and secured with HTTPS using Let’s Encrypt and cert-manager. ⚠️ No Authentication: This is a functional prototype. Anyone with a valid email can create or use a wallet. 💡 Key Features Create / Retrieve Wallet: Enter your email to create or retrieve a wallet. Instant dashboard redirection. Deposit Funds: Supports cUSD, cNGN, cXAF, and cEUR. View Wallet Balances: See balances in all supported currencies and their total in cUSD. Swap Currencies: Swap any currency using real-time FX rates. E.g., convert cUSD → cNGN. Transfer Funds (Email-based): Send money to another user via email. Automatically converts between currencies. Transaction History: View deposits, swaps, and transfers all in one place. Audit Logging (Internal): Captures user actions: UserID, IP, Device, Country, Browser, and Timestamp. Stored securely in the database. Only viewable with DB access. 🧩 Tech Stack & Deployment Backend: Golang (Go) Frontend: React.js Containerization: Docker Orchestration: Kubernetes Security: HTTPS via Let’s Encrypt & cert-manager DevOps: Kubernetes Ingress with TLS, deployed on a secure cluster 🔗 Source Code Backend (Golang): https://github.com/Kjasuquo/borderless-money Frontend (React): https://github.com/Kjasuquo/borderless-money-frontend golang fintech app, react secure app, https golang react, deploy fintech app, kubernetes ssl, let's encrypt, cert-manager, k8s react go, multi-currency wallet, cross-border payments, build fintech app from scratch
