DevOps Engineer — AWS Infrastructure Setup & CI/CD Pipeline

We are migrating from a single Heroku instance to a proper AWS infrastructure as we prepare for Series A. We need a DevOps engineer to design and implement a multi-environment AWS setup (dev, staging, prod) using ECS Fargate, set up a GitHub Actions CI/CD pipeline with automated testing gates, configure a CloudFront CDN, implement RDS PostgreSQL with automated backups and read replicas, set up CloudWatch monitoring and PagerDuty alerting, and document everything thoroughly in Notion. We need this done in 3 weeks — urgency is real, budget is flexible for the right person.
