Mateus Getulio Vieira

I’m looking for a senior role where I can work across backend, cloud, CI/CD, and production systems. I value ownership, good engineering practices, and a team where I can keep learning and improving systems. At OnTheGoSystems/WPML, I built and launched an AWS-based customer-scoring platform that classified 100,000+ customers, and rescued a critical E2E pipeline from 4/24 to 24/24 passing jobs while cutting runtime nearly in half. I work across backend delivery and production reliability, including AWS, CI/CD, observability, incident response, testing, and internal tooling. I’ve also built retention analytics and REST extensions, automated blue-green cache purging, investigated production failures, and mentored six engineers through onboarding, debugging, code review, and knowledge transfer.
