Backend Software Engineer
I build enterprise-grade backend systems, fiscal integrations, and mission-critical Java infrastructure for companies that cannot afford failure.
Selected Work
Java application that parses raw action payloads from the legacy integrator, renders them as a structured XML editor, and dispatches corrected documents to the MasterSAF API, eliminating the need for Burp Suite/Postman in fiscal document correction workflows.
Designed and implemented the Java backend logic for IBS, CBS, and IS compliance under Brazil's 2024 tax reform. Processes thousands of electronic invoices daily in a regulated production environment with strict validation rules and Oracle DB pipelines.
Bidirectional data synchronization layer between SAP and Oracle systems, handling schema mismatches, conflict resolution, and financial data integrity. Critical for daily reconciliation and compliance reporting.
About
I'm a backend engineer with 4+ years working inside enterprise environments: fiscal systems, SAP integrations, and Java infrastructure that processes thousands of documents per day.
I care about correctness, system design, and building things that last.
