What I'm looking for

I'm looking to build reliable backend systems, integrations, and microservices, contributing to scalable products while collaborating with international teams.

At Marlabs Brazil, I develop and maintain enterprise UCaaS and CCaaS solutions for CallTower, collaborating daily with an American team in English.

I build integrations for Microsoft Teams, Cisco Webex, and CT Cloud, and support carrier-grade VoIP architectures using Sansay and Metaswitch. I led a FaxBack integration that routed 8,000+ legacy fax devices to the cloud and reduced fax-related support tickets by 92%.

Previously at Deltatec, I built Node.js, TypeScript, Nest.js, and MySQL microservices for e-commerce, including a RabbitMQ order webhook that reduced fulfillment time by 70%. I also delivered a Java and Spring employee management system and implemented CI/CD pipelines that reduced update implementation time by over 400%.
