· Build and support secure APIs with strong authentication and authorization (OAuth2/OIDC, JWT), input validation, secrets management, and encryption in transit and at rest.
· Design and operate AWS-hosted services using EC2, API Gateway, S3, Lambda, and other relevant managed services, including IAM, VPC networking, load balancing, and Cloud Watch monitoring.
· Own CI/CD pipelines for build, test, and deployment (e.g., Jenkins, Git Hub Actions, AWS Code Pipeline/Code Build, or similar), and independently diagnose and resolve pipeline failures.
· Provide production support for business-critical applications, including incident triage, root-cause analysis, performance tuning, and post-incident remediation.
· Implement logging, auditing, and monitoring for applications and APIs to support traceability, compliance, and rapid incident response.
