Gergana developed and maintained core features for the ethereum/kohaku-extension and AmbireTech/ambire-common repositories, focusing on robust UI/UX, multi-network support, and secure asset management. She engineered end-to-end flows for rewards, governance, and onboarding, integrating React and TypeScript with smart contract interactions to ensure reliability and clarity for users. Her work included optimizing portfolio data, implementing domain-based policy revocation, and enhancing transfer validation logic to reduce user risk. By refactoring validation pipelines, improving error handling, and introducing concurrency controls, Gergana delivered scalable, maintainable solutions that improved user experience and developer productivity across both frontend and backend systems.

January 2026: Implemented domain-based auto-login policy revocation feature with tests, enabling revokeAllPoliciesForDomain to revoke all policies for a given domain and validating behavior across multiple accounts. No major bugs fixed this month. Impact: provides users with stronger security controls and policy management at the domain level, reducing risk and improving policy compliance. Technologies/skills: feature development with test-driven validation, unit/integration testing, multi-account test coverage, and code quality improvements in AmbireTech/ambire-common.
