As a Senior Backend & Platform Engineer, I design and operate backend services. My work focuses on backend architecture, database performance, CI/CD, production reliability, and scalable distributed systems supporting enterprise applications. • Designed and maintained cloud-native backend services supporting thousands of production users. • Reduced MySQL query latency by up to 60% by optimizing execution plans, indexing strategies and query patterns. • Designed GitHub Actions CI/CD pipelines enabling automated and low-risk production deployments. • Participated in incident response, root cause analysis and postmortem improvements for mission-critical production systems. • Collaborated with backend, platform and product teams to improve scalability, observability and engineering productivity.

Worked on backend and platform engineering for enterprise systems, designing scalable APIs, distributed integrations and cloud-native services with a strong focus on reliability, database performance and automation. • Designed scalable backend services using PHP, NestJS and TypeScript for multi-tenant enterprise platforms. • Architected REST APIs and integrations supporting distributed enterprise systems. • Engineered fault-tolerant services handling high-concurrency production workloads. • Developed a CT-e platform processing high transaction volumes under strict compliance requirements. • Optimized PostgreSQL, Oracle and SQL Server workloads through indexing, query tuning and execution plan analysis. • Automated ERP integrations and operational workflows, improving efficiency across multiple business processes. • Built containerized applications and deployment pipelines using Docker and CI/CD.

Led cloud modernization initiatives for mission-critical healthcare platforms, designing Cloud infrastructure, Kubernetes environments and highly available backend services supporting healthcare systems deployed across hundreds of municipalities. • Led the migration of healthcare platforms to Cloud supporting deployments across more than 200 municipalities in 10 Brazilian states. • Designed highly available infrastructure using EKS, PostgreSQL Multi-AZ and Infrastructure as Code with Terraform. • Implemented PostgreSQL read replicas to improve reporting performance and database scalability. • Built centralized observability using Prometheus, Grafana and ELK Stack, improving monitoring and incident response. • Participated in disaster recovery planning and production incident response for healthcare platforms requiring continuous availability. • Containerized legacy applications using Docker and modern deployment workflows.

• Supported cloud and on-premise infrastructure operations ensuring system availability • Assisted in troubleshooting production incidents and improving system reliability • Maintained servers, storage, and networking components in high-usage environments

• Provided IT and infrastructure support across enterprise systems • Assisted in network administration, system maintenance, and hardware troubleshooting • Supported implementation of security updates and operational improvements

Completed coursework in software development, databases, systems analysis, networking, software engineering, and systems architecture
