Senior software engineer building scalable React and backend services with performance-focused distributed systems.
BrazilWhat I'm looking for
I’m a Senior Software Engineer with 6+ years of experience building scalable web applications and backend services. I focus on production-grade frontend dashboards, backend APIs, cloud-native services, and distributed systems—delivering measurable performance and reliability gains.
In my recent role, I improved dashboard load performance by 38% with React 18, route-level code splitting, memoization, and optimized API state management. I also reduced average API response time from 820ms to 470ms by improving query structure, adding indexes, and introducing Redis-based caching.
I strengthen delivery through CI/CD automation and AWS-based infrastructure, including GitHub Actions, Docker, and AWS ECS Fargate. I’ve also reduced deployment time by 55%, expanded REST API coverage by 45%, and collaborate closely with product, design, QA, and engineering teams in Agile sprints.
