• 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 CloudWatch monitoring.

• Own CI/CD pipelines for build, test, and deployment (e.g., Jenkins, GitHub Actions, AWS CodePipeline/CodeBuild, 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.

• Write clean, well-tested code, including unit, integration, and contract tests, and enforce code quality through peer reviews and automated checks.

• Participate in security reviews, threat modeling, and vulnerability remediation, and keep dependencies and runtime environments patched.
