During April 2025, Stockmann updated promotional screenshots for the bitfireAT/davx5-ose repository to align with the latest Android user interface, ensuring marketing materials accurately reflected the current application state. This work involved generating and validating UI assets across multiple Android device profiles, leveraging skills in App Store Optimization, Git version control, and cross-device asset management. By maintaining consistency between the product UI and its promotional representations, Stockmann reduced the risk of user confusion and improved onboarding effectiveness. The changes were tracked with explicit commit references, demonstrating disciplined workflow and attention to asset QA traceability, though the scope was limited to a single feature.
