PROFILE
Gustavo Randi
Gustavo Randii developed and enhanced electronic invoicing and validation frameworks in the Unimake/DFe repository, focusing on backend and API development using C#, XML, and .NET. Over five months, he delivered features such as multi-municipality NFSe onboarding, XML validation frameworks, and standardized cancellation APIs, addressing integration, data accuracy, and regulatory compliance. His work included performance testing for certificate loading, schema-driven XML validation, and flexible data submission mechanisms, often leveraging design patterns and test-driven development. By restructuring validation logic and expanding test coverage, Gustavo improved reliability, maintainability, and interoperability, demonstrating depth in configuration management and backend engineering for government invoicing systems.

Jan 1, 2026January 2026: Delivered production-ready NFSe readiness in Unimake/DFe by enabling multi-municipality onboarding, data handling enhancements, and standardized cancellation services. Key features include onboarding NFSe for Joinville, Contagem, Vacaria, Sinop, and Formiga with version 1.01 and COPLAN alignment; NFSe XML data handling improved via GZip decompression and UsaCertificadoDigital flag across multiple municipalities; a unified NFSe cancellation API extended to Contagem, Rolândia, Boituva, Agudo, Vacaria, Getúlio Vargas, Uruguaiana, Cachoeira do Sul, Itaperuna, and Araruama. These changes improve integration reliability, security, and operational efficiency for government invoicing partners. Achieved with versioned deployments, RTC updates, and adherence to PRONIM standards, reflecting strong configuration governance and deployment discipline.

Dec 1, 2025Month: 2025-12 — Key deliverables for Unimake/DFe: XML Validation Framework Enhancements across NFe/NFCe/CTe and NFSe v3.01 with RTC schema. Implemented XML version extraction and Authorization XML preparation to streamline validation; expanded test coverage with new XML test files; added event-tag support for XML identification; introduced NFSe v3.01 support with new RTC-tag schema for Joinville; updated config and sample XMLs to conform to the new NFSe schema. Impact: higher validation accuracy, broader schema conformance, reduced risk of regulatory non-compliance, and faster validation cycle. Skills: XML processing, schema validation, test-driven development, configuration management, cross-team collaboration.
