Case study / enterprise delivery

Turning a complex lease journey into a reusable frontend system.

ING Lease · Senior Frontend Engineer and Team Lead · 2023–2025

5engineers led
2core journeys delivered
3delivery pillars: forms, APIs, accessibility

01 / Challenge

Make complexity feel predictable.

A multi-step leasing experience had to combine calculations, validation, API integration, and accessible interaction without creating a fragile collection of one-off screens.

02 / Decisions

Design the system, not only the screens.

I led a five-person team around reusable form patterns, clear component boundaries, consistent validation states, and dependable REST integration for the journey and smart calculator.

03 / Result

Ship the journey and leave reusable foundations.

We delivered the digital lease journey and calculator while establishing frontend patterns that could support subsequent flows with greater consistency.

Client work is described at a high level to respect confidentiality.
