Scalable fintech portal built with Laravel, Vue.js and Stripe

The client runs a digital wallet and micro-payment service for freelancers, small businesses and remote workers. Fast user growth had outpaced their original platform.

The challenge

• Slow transactions: payment delays frustrated users and hurt trust.
• Weak security foundations: the legacy system lacked the modern compliance features a fintech needs.
• Rigid architecture: adding a feature or payment method took significant effort.
• No real-time data: users could not follow transactions or balances as they happened.
• Hard integrations: Stripe, Plaid and tax calculators were difficult to connect cleanly.

What we built

Back end: Laravel

An API-first Laravel service connects the web dashboard, mobile apps and third-party APIs. Laravel Passport handles authentication and token management, and payment flows use encrypted tokens and two-step verification. Stripe processes payments, recurring charges and refunds, and supplies financial reporting. Invoice generation, email notifications and transaction logs run as background jobs on Laravel queues with Redis, so the system stays responsive.

Front end: Vue.js

A Vue.js single-page dashboard lets users manage funds, see payment history and generate reports. WebSockets push live balance changes and incoming transactions without a page refresh, and Vuex keeps account state and transaction status consistent.

Payments and real-time data

Stripe webhooks give users immediate confirmation of successful or failed payments. An analytics dashboard built with Chart.js tracks income, expenses and fees. The platform supports multiple currencies, with conversion rates updated through an API.

Compliance and security

Sensitive data is encrypted at rest and in transit, designed with GDPR and PCI DSS requirements in mind. A full audit log records critical actions and transactions, and role-based access control protects sensitive actions and data.

Testing and deployment

We simulated peak usage with thousands of concurrent transactions. A GitHub Actions CI/CD pipeline makes releases faster and safer, and the platform runs on AWS with auto-scaling and load balancing.

Outcome

Payments and balances now update in real time, the API-driven, modular codebase makes new payment methods easy to add, and the platform handles far more users than before. We worked with the client's compliance and legal teams during rollout and continue to support the platform with new features and updates.
