Apr 1, 2026April 2026 — Delivered a multi-document QR Code generation framework (NFCe, CTe, MDFe, NF3e) with new interfaces/processors, improved error handling for status responses, XML configuration validation, and batch QR code generation for MDFe. Added asynchronous QR code URL formation in the MDFe authorization flow and ensured correct processor selection across document types to align with latest standards and improve user experience. Strengthened municipality-level digital certificate management with better certificate usage identification, version retrieval, and removal of NFCe enveloping to streamline flows and reduce complexity. These changes deliver faster, more reliable document workflows, improved security posture, and easier maintenance, translating to reduced support overhead and better compliance. Technologies demonstrated include interface-driven design, XML config validation, robust error handling, batch processing, asynchronous processing, and certificate management.
