I've built and evolved scalable corporate applications at Econocargo Gestão Colaborativa, with a focus on data architecture and transaction-volume growth.

I integrated REST APIs, webhooks, OAuth 2.0, JWT, and mTLS with Bradesco, PagBank, and Sicoob, helping secure data in transit. I also connected Tray and Tiny ERP to process and transform critical business data at scale.

I developed ERP modules in GeneXus for Finance, CRM, TMS, NF-e, and CT-e, applying data modeling practices for BI and analytics. My work spans PostgreSQL, MySQL, SQL Server, Elasticsearch, PHP/Laravel, and Vue.js 3.

I've also automated corporate workflows with Python, n8n, and LLMs, orchestrating data pipelines and information processing. Earlier, at Faculdade Católica de Vitória's Software Factory, I contributed across analysis, design, implementation, and testing throughout the software development lifecycle.
