Message

At The Access Group, I work across the software lifecycle, from architecture design to production deployment. I led Java 8-to-17 migrations and developed Spring Boot microservices in AWS Kubernetes environments.

I integrated DOJO for payments and BRAZE for CRM across React and React Native applications, contributing to improved transaction success and customer engagement. I also architected AI workflow orchestration pipelines using MCP and n8n, integrating Devin-based analysis into the development lifecycle.

At Banco do Nordeste do Brasil, I contributed to corporate property appraisal and budget analysis systems using Java, Spring Boot, React, and TypeScript. Earlier, I contributed to modernizing government systems at SergipeTec and legacy services at Perinity, working with Java, databases, and automated testing.
