Over a two-month period, contributed security-focused features to status-im/status-desktop and logos-co/nomos, emphasizing privacy and accessibility. In status-im/status-desktop, implemented a two-layer QML solution to prevent seed phrase exposure by ensuring unrevealed words remain inaccessible to screen readers and UI automation until explicitly revealed, using accessibility API controls and guarded data bindings. For logos-co/nomos, delivered a policy update enabling faucet fund requests via public key alone, removing the need for team credentials and reducing credential exposure. Maintained thorough documentation and release notes in Markdown, demonstrating strengths in technical writing, front end development, and secure-by-default engineering practices across both projects.
