My approach
My approach
My approach
I applied a comprehensive, user-centred UX process to transform waste management into a clear, efficient and actionable experience for CSR managers.
Each step was guided by three priorities: readability, time savings and regulatory compliance.
Key steps:
Analysis of context and constraints
User research and understanding of needs
Definition of personas and journeys
Ideation and design
Prototyping and testing Iteration and optimisation
I worked in an agile environment in close collaboration with the teams, adapting priorities and deliverables to the pace of the MVP challenges.

Customer journey and User stories
The customer journey analysis led to UX/UI recommendations for each stage of the journey.
Based on these recommendations, I wrote the user stories and helped prioritise them with the team to align the MVP's UX objectives.
