Backend software engineer at Alloc IT Solutions who cut ERP checkout search response time by about 40%.

Brazil
Message

At Alloc IT Solutions, I cut product search response time in an ERP checkout module by about 40% by removing redundant requests and duplicated code. I also replaced SAP B1IF with a Spring Boot REST microservice that connected PostgreSQL, SAP HANA, and SQL Server, eliminating recurring synchronization failures in two weeks.

At Alloc IT Solutions, I modernized authentication with OAuth 2.0 and JWT, and migrated critical functionality from Java Swing to Spring Boot and Angular. As a freelancer at Zelium, I structured the Portal do Parceiro with a multi-tenant PostgreSQL database and integrations isolated behind the backend; at NexTI-Unifap, I led four interns on a Python/Django project that had been paused for a year and helped deliver it to the client.
