- Continuously improve logging standards and observability, including structured logging across Lambda, ECS, and EC2.

- Set up custom metrics and log-based alerts to detect errors, bottlenecks, and anomalies.

- Build and maintain operational dashboards to monitor system health.

- Participate in incident response, perform root cause analysis, and implement preventive actions.

Troubleshooting & Production Support :

- Proactively monitor and investigate production issues across AWS, Docker, Lambda, ECS, RDS, and Linux-based systems.

- Quickly identify the root cause of live issues and provide short-term mitigation and long-term fixes.

- Collaborate with developers to debug application-layer and infrastructure-level problems.

- Own and continuously improve incident response, resolution time, and reliability processes.

Linux System Administration :

- Administer and troubleshoot Linux-based EC2 instances (Amazon Linux, Ubuntu).

- Handle OS-level performance tuning, networking, and patch management.

- Create system-level scripts and automation for routine DevOps tasks.

Required Skills & Experience :
