This was my first professional step into cloud computing, where I built the foundation of my DevOps and cloud career. I started as an intern and quickly grew into a hands-on engineer working with real production environments. The company played a key role in shaping my technical understanding and guiding me into a long-term career in cloud infrastructure. Key responsibilities and achievements: Built and managed AWS infrastructure using Terraform, including reusable modules and environment provisioning Troubleshot and resolved Terraform drifts, state file conflicts, and environment mismatches Collaborated with senior engineers to design new cloud environments based on client requirements Helped maintain IaC standards, documentation, and deployment consistency across projects Assisted in automation and server configuration tasks using Ansible Gained practical exposure to CI/CD pipelines, Linux systems, and AWS core services Actively learned and applied best practices from AWS Solutions Architect, Cloud Practitioner, Terraform Associate, CKA (Kubernetes Administrator), and Ansible training courses This role was instrumental in building my foundation in cloud computing, Infrastructure as Code, and DevOps principles, giving me the confidence and technical depth to move into larger infrastructure design and automation projects later in my career.
