Katllen Sirotenco

Over three months, contributed to Unimake/DFe by building and refining features for NF3e protocol consultation, NFSe integration, and municipal tax system support. Developed services for querying NF3e document status, standardized XML handling, and expanded municipality coverage, including support for Natal, RN. Applied C#, XML, and PHP to implement API integrations, unit testing, and schema validation, ensuring reliable data transmission and compliance with fiscal requirements. Addressed bugs in XML structure and configuration, improved code quality through refactoring, and maintained repository stability by aligning features with the product roadmap. The work emphasized robust backend development and thorough software testing practices.

November 2024 monthly summary for Unimake/DFe: Initial implementation of the NF3e Protocol Query Service (ConsultaProtocoloNF3e) was completed, including service configuration, XML handling, and unit tests. The effort also included code cleanup and naming consistency (ConsSitNF3e) and the creation of targeted unit tests for NF3e. However, the feature was subsequently reverted (rollback) to align with the current product roadmap. The work delivered established a solid foundation for NF3e status querying, improved code quality, and maintained test coverage while ensuring the repository remains stable for production use.
