During September 2025, this developer enhanced voting security and reporting features for the sigevaBack repository by refactoring OTP generation and validation, improving expired OTP cleanup, and expanding API documentation for regional management and vote validation. They introduced an election reporting endpoint that compiles election details, votes, and participants, while updating vote validation logic to support additional user states. On the sigevaFront repository, they improved UI reliability by addressing type safety issues across components, refining optional properties and nullability. Their work leveraged TypeScript, Node.js, and React, resulting in more secure, auditable voting flows and a more maintainable, stable front-end codebase.
