Software Engineer
I build backend systems, APIs, and integrations that actually work in production. Strong foundation in enterprise engineering — evolving toward modern development with TypeScript, Node.js, and clean architecture.

Integration
NF-e Integration Engine
Built a robust Java-based integration engine that handles the full lifecycle of NF-e (Nota Fiscal Eletrônica) documents — from SEFAZ communication and XML parsing to business rule validation, error recovery, and Oracle DB persistence. Handles thousands of documents per day with guaranteed delivery semantics.
- Processes 10,000+ fiscal documents per day with 99.9% uptime
- Complex business rule engine with configurable validation layers
- Automatic retry and dead-letter queue for failed documents
