Diana Savvatina contributed to trilitech/umami-v2 by engineering robust wallet integration and UI/UX improvements for Tezos dApps. Over five months, she enhanced WalletConnect and Beacon flows, focusing on error handling, signing reliability, and onboarding. Diana refactored React components, standardized Tezos symbol usage, and introduced modular architecture for multi-chain support using TypeScript and JavaScript. Her work included implementing batch signing modals, mnemonic import enhancements, and analytics integration, all supported by expanded Jest test coverage. By addressing critical bugs and refining user flows, Diana delivered maintainable, scalable solutions that improved reliability, user experience, and codebase structure across the application.

March 2025 — trilitech/umami-v2: Delivered targeted UI improvements and architecture changes that enhance user experience, consistency, and maintainability. Key features delivered: mobile seed phrase verification UI improvements (ui: column words in verify on mobile); local send flow UI refresh with AddressTile (ui: account logo on local send); Tezos symbol standardization across UI (ui: replaced ꜩ with XTZ across the whole umami); Tezos indexer package refactor to chains package enabling multi-chain support (Web UMA-1264). Major bugs fixed: NFT video playback fix (fix: nft video); Password change validation fix (fix: check confirmed password on password change). Impact: smoother onboarding and sending UX, consistent token display, modular and scalable multi-chain architecture, plus improved validation and test coverage. Technologies/skills demonstrated: UI/UX refinements in React, ReactPlayer props usage, TypeScript module refactor and monorepo packaging, and test coverage for critical user flows.
