Work: monitoring, alert triage, routine maintenance, incident response, certificates/security updates, and infrastructure decision-support. No application development or architecture ownership expected. Stack: AWS Elastic Beanstalk, ECS, Lambda, RDS, ElastiCache, Redshift, S3, SQS, CloudFront, WAF, Route 53, IAM, CloudWatch; MongoDB Atlas, Elastic Cloud, n8n, Metabase, Sentry, Bitbucket Pipelines.
