Maintain and evolve AWS infrastructure using CloudFormation, AWS SAM, and Terraform.
Build, update, and support TypeScript-based Lambda functions, APIs, and microservices.
Improve platform reliability, performance, and resilience through automation and DevOps best practices.
Enhance and run CI/CD pipelines (GitHub Actions) with automated testing and deployment.
Containerise where needed using Docker for local development and ECS workloads.
Apply strong security, operational readiness, and GDS-aligned standards across the platform.Essential Skills & Experience
