What I'm looking for

I'm looking to build scalable, customer-facing applications where I can own features end-to-end, turn complex workflows into intuitive experiences, and contribute to UI/UX and product development.

At Rentoza, I build production React applications and customer-facing workflows, improving performance through component memoisation, lazy loading, and efficient rendering.

I optimised the customer verification journey with straight-through processing, reducing manual intervention by 40%. I also integrate RESTful APIs for real-time subscription lifecycle management and translate Figma designs into reusable components within a shared design system.

I built the Rentoza Unlock mobile app from the ground up using React Native and Expo, including frontend and backend functionality for mobile subscription payments and secure MDM access controls.
