Work
Backend services, enterprise integrations, and data systems built for production environments where correctness is non-negotiable.
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.

Node.js/TypeScript REST API that acts as a clean interface between internal backend systems and consuming applications. Replaces direct database access with versioned, typed endpoints connected to Oracle DB.
Modular ETL pipeline with configurable per-entity transformation rules, run logging, error capture, and replay support. Processes data between Oracle sources and target systems with full observability.
SQL optimization tools and Power BI dashboards built to analyze execution plans, recommend index strategies, and monitor query performance in real time across a production Oracle database used by financial and fiscal workflows.
