In June 2025, Ines Goldschmidt enhanced the VIP Referral Card feature in the Catappult/appcoins-wallet-android repository, focusing on reliability and maintainability. She addressed a countdown timer issue by ensuring it used the correct start date for future codes and removed hardcoded code-length assumptions, improving the accuracy of referral code handling. Ines refactored VipReferralCardComposable.kt imports to streamline the UI codebase, supporting long-term maintainability. She also polished the user-facing copy for consistency. Working primarily with Kotlin and Jetpack Compose, Ines demonstrated a methodical approach to Android development, delivering targeted improvements that reduced support friction and increased user trust in the referral process.
