About
I'm a software engineer with 4+ years building backend systems, APIs, and integrations in demanding corporate environments. My foundation is in Java, Oracle, and enterprise-grade systems — and I'm actively evolving toward modern development with TypeScript, Node.js, and clean architecture.
I've worked inside systems most developers prefer to avoid — legacy codebases, SAP interfaces, Oracle databases carrying years of business logic, NF-e pipelines that cannot fail. That experience shapes how I approach engineering: thoroughly, with respect for complexity.
My goal is to keep building — better APIs, more robust integrations, and software that solves real problems in production, not just in theory.
At a Glance
What I Build
Concrete areas where I deliver production-ready solutions.
REST APIs & Backend Services
Clean, typed REST APIs in Node.js/TypeScript and Java — structured contracts, proper error handling, and maintainable architecture.
System Integrations
Bidirectional data flows between SAP, Oracle, and external systems. Schema mapping, conflict resolution, and full audit trails.
Data Pipelines & ETL
Python pipelines that extract, transform, and load data between heterogeneous systems — with validation, logging, and replay support.
Database Engineering
Oracle DB design and optimization — query tuning, index strategy, PL/SQL packages, and data modeling for high-throughput systems.
Process Automation
Python and Java scripts that eliminate manual workflows — data reconciliation, compliance checks, and scheduled operational tasks.
Fiscal & Compliance Systems
NF-e and DFe automation — SEFAZ communication, XML validation, business rule engines, and regulatory reporting pipelines.

From enterprise Java and Oracle to modern TypeScript, Node.js, and REST APIs.
