Delivery timeline

The Financial Technology Challenge

A growing FinTech company had outgrown their initial customer-facing portal: originally built by a freelance team with no documentation, poor performance on mobile, and a 4.2-second average load time that was directly hurting conversion rates and support ticket volumes.

Our Application Development Solution

We audited the existing codebase, defined a new architecture, and rebuilt the portal as a performant Vue 3 / Nuxt application with a Node.js API layer. We introduced component-level caching, lazy loading, a design system, and integrated their KYC and payment provider APIs. The project was delivered in 14 weeks with zero data loss.

The Outcome

Average page load dropped from 4.2 seconds to 0.9 seconds. Customer support tickets related to portal usability fell by 61% in the first month. The new design system accelerated all subsequent feature development cycles.

FAQ

Questions About Application Development

When should a business rebuild a portal rather than patch the existing one?

A rebuild makes sense when the existing codebase has no documentation, the architecture cannot support required performance or security improvements, or the technical debt means each new feature takes disproportionate time to deliver. If patching costs more over 12 months than rebuilding, rebuild. This project had all three indicators pointing clearly to a rebuild.

How do you protect financial data during a portal rebuild?

We conduct a security audit at the start of every FinTech project, implement all OWASP Top 10 controls, use encrypted data transmission throughout, and test against common vulnerability patterns before any code touches production. All credentials and API keys are stored in environment-specific secret management, never in version control.

Can the rebuilt portal support future features without accumulating technical debt?

Yes the rebuild included a documented component library and design system. New features are built from documented, reusable components, which means faster development cycles and consistent UI quality. The new architecture also separates the frontend and backend cleanly, so each can evolve independently.
