A SaaS fintech payment application built on Android OS for point-of-sale hardware.

A SaaS fintech payment application built on Android OS for point-of-sale hardware.

MY CONTRIBUTION

Solo Product Designer responsible for the end-to-end UX strategy, interaction architecture, and UI design. Partnered closely with the Head of Development and engineering team to align product decisions with technical feasibility.

ROLE & CONTEXT

The product had evolved without a structured UX foundation. With no design system or documented user flows, I established the interaction framework, navigation principles, and design consistency across the platform

CHALLENGE

Evaluating and evolving the UX foundation of a live fintech payment platform. The challenge was to improve usability, streamline existing workflows, and introduce a more modern visual language while maintaining continuity with the broader product ecosystem and respecting Android OS constraints.

MAPPING & AUDIT

MAPPING & AUDIT

The starting point was the live production app. I mapped every screen, every state, every dead end — building a complete picture of what existed before proposing anything new. That audit became the shared reference point between design and development: a clear before, against which every improvement could be justified.

INTERACTION IMPROVEMENTS

INTERACTION IMPROVEMENTS

From the audit, I identified the highest-impact areas for redesign — focusing on user flow logic, screen hierarchy, and interaction consistency. New patterns were proposed in direct dialogue with the Head of Developer, validated against what the current architecture could actually support. No proposal without a feasibility check.

WIREFRAMING

WIREFRAMING

The project is currently in active wireframing phase. Interaction patterns are being translated into concrete screen layouts — defining spacing, component behaviour, and flow logic before any visual decisions are locked in. Each wireframe is reviewed with the development team to ensure technical alignment from the start.
