At ContainerGrid, a Munich-based SaaS startup in the recycling and waste management sector, I worked as the sole UX/UI Designer and junior product manager.
Over two years, I led key product and design initiatives that modernized the platform, established a clear design system, reduced feature implementation time, and improved onboarding and customer workflows.
My work was grounded in continuous user research, ranging from stakeholder interviews and shadowing operational staff to wireframe testing and co-creation sessions with clients. This ensured that every design decision addressed real-world friction and delivered measurable impact.
Feature improvement: Order Modal & Scheduling Interface
Problem: Clients struggled with outdated scheduling logic and unclear status tracking, leading to delays and manual coordination.
My Contribution: After conducting UX research, I redesigned the order management interface with clear status indicators, logical grouping of actions, and batch editing options.
Result: Improved user comprehension and reduced redundant clicks; internal feedback reported task time cut nearly in half.
Feature design: Smart Route Planner
Problem: oute optimization was manual and error-prone, especially for routes with over longer distances.
My Contribution: After conducting UX research, I designed a brand new real-time route-planner that not only allowed users to create new routes, but also helped them keep an eye on the ecological balance. This modal was also connected to the driver app.
Result: Reduced route planning time by ~45% and helped dispatchers respond to changes more fluidly.
Feature design: Remote Weighing via Driver App
Problem: Manual weighing processes that could only be filled on the desktop app after-the-fact required additional staff and paperwork.
My Contribution: Designed mobile workflows for weighing and photographing material directly via the app, synced with the central dashboard. Integrated error-checking logic and clear CTAs for drivers.
Result: Reduced route planning time by ~45% and helped dispatchers respond to changes more fluidly.
Feature improvement: Automated Compliance Documentation
Problem: Recycling proofs and delivery notes were manually gathered for reporting, error-prone, and legally sensitive.
My Contribution: Mapped user journeys and edge cases for gathering all autogenerated documentation, improving data hierarchy and output formatting.
Result: Reduced document preparation time from hours to minutes. Legal advisors noted improved consistency and audit readiness.
Feature improvement: Smart Invoicing Interface
Problem: Users were frequently confused about which invoice line items corresponded to which service orders. This lead to internal delays, client complaints, and manual corrections.
My Contribution: I redesigned the invoicing interface to clearly map line items (Belegposten) to their originating orders. Using visual grouping, iconography, and improved labels, I introduced clearer connections between orders on the left and their associated invoice rows on the right. We also introduced validation logic for common error patterns and made the structure more flexible for repeat clients and recurring invoices.
Result: The redesign significantly reduced billing errors and eliminated unnecessary back-and-forth with clients. Internal testing showed that invoice creation for complex, multi-order cases became 30% faster, while billing correction requests dropped by roughly 50% within the first two months of rollout.
