Hire the Best AWS Developers
in Brazil

You need your AWS environment to be reliable, secure, cost-efficient, and easy to operate not a source of stress every time you deploy, scale, migrate, or troubleshoot. That is where I can help. I work with startups, SaaS companies, and small businesses that need to build, migrate, secure, automate, or optimize AWS environments using services such as EC2, ECS, Fargate, RDS, CloudFront, WAF, Route 53, Terraform, CI/CD, Docker, CloudWatch, and Secrets Manager. If your application is still running on a VPS, manual server, unstable deployment process, exposed infrastructure, or an AWS setup that became expensive and hard to maintain, I can help you turn it into a cleaner, safer, and more production-ready cloud environment. You can work with me when you need to: ✅ Deploy your application on AWS I can help you deploy Docker, backend, frontend, API, or SaaS workloads using EC2, ECS Fargate, ECR, ALB, Route 53, ACM, CloudFront, RDS, and CloudWatch. ✅ Migrate your infrastructure to AWS If you are moving from DigitalOcean, Hetzner, VPS, Coolify, cPanel, another AWS region, or a manual server setup, I can help you plan and execute the migration while reducing downtime and protecting your data. ✅ Automate your deployments I can help you replace manual deployments with CI/CD pipelines using GitHub Actions, AWS CodePipeline, CodeBuild, Docker, ECR, ECS, rollback strategies, and secure IAM access. ✅ Build infrastructure with Terraform You get repeatable, documented, and scalable infrastructure using Terraform or CloudFormation, instead of manual AWS console changes that are hard to track and maintain. ✅ Secure your AWS account and application I can review and improve IAM, security groups, WAF, KMS, Secrets Manager, GuardDuty, Inspector, Security Hub, TLS, CloudTrail, and general AWS security practices. ✅ Reduce your AWS costs If your AWS bill is growing and you are not sure why, I can analyze your environment using Cost Explorer, Trusted Advisor, Compute Optimizer, rightsizing, unused resource cleanup, and practical FinOps recommendations. ✅ Improve monitoring and reliability I can set up CloudWatch logs, alarms, dashboards, metrics, SNS/Lambda alerts, Slack notifications, and operational visibility so you know what is happening before your users complain. Why clients work with me: • 5x AWS Certified, including AWS Solutions Architect Professional • Hands-on experience with production systems in the financial sector • Strong background in AWS architecture, DevOps, security, automation, and observability • Clear communication, organized documentation, and practical execution • Focus on secure, reliable, scalable, and cost-efficient cloud environments • 5-star Upwork feedback for AWS delivery and communication Recent work includes building an AWS-based prerendering solution using Node.js and Puppeteer to improve crawler visibility and SEO for a JavaScript SPA. If you want your AWS environment to be cleaner, safer, easier to deploy, easier to monitor, and better prepared for growth, send me a message and I will help you define the best path forward.
