Designed Holder & Enterprise wallets for a cross platform, cutting onboarding time by 25% and QA issues by 25%.

Kredential is a credentialing platform that helps students and universities issue, manage, and verify verifiable credentials (VCs) in a secure, decentralized way, built for the EBSI framework. The platform has two sides: a Holder Wallet for students to store, share, and verify credentials, and an Enterprise Wallet for universities to issue, approve, and revoke them, designed for clarity and scale while staying fully EBSI-compliant.

UI/UX Designer

2023 to 2024

Decentralized identity and verifiable credentials are technically complex concepts. The challenge was designing an experience that felt secure and trustworthy to students with no blockchain background, while giving institutions a compliant, scalable tool to manage credentials at volume.

Joined a full day workshop at University of Maribor (FERI) on decentralized identity to ground the design in real academic use cases

Researched competitors (Accredible, SmartCertificate, TrueLayer) and reviewed EBSI documentation, DID methods, and trust registries

Mapped user flows and scenarios in FigJam, covering DID login, first time verification, credential issuance, and employer verification requests

Designed a full UI system for both wallets, prioritizing accessibility and visual hierarchy

Created a custom mascot to add warmth and trust to the Holder Wallet's onboarding experience

Led manual QA across both platforms, testing edge cases and logging issues in Jira to ensure the build matched the design

25% faster onboarding walkthroughs during user testing, driven by a redesigned onboarding flow with the mascot and clearer visual examples

20% fewer user questions during internal demo sessions

25% reduction in QA issues after refining edge case handling (empty states, error messages, credential status flows) across both wallets
