About Amit Jaiswal
Currently serving as a Linux Administrator at HCL Technologies, I specialize in supporting enterprise production environments utilizing RHEL 7/8/9. My responsibilities include OS patching via Red Hat Satellite, incident troubleshooting, user access and permission management, and ensuring high availability through storage, filesystem operations, and NFS administration. Pursued a B.Sc. in Computing and Design at Birla Institute of Technology and Science, Pilani, I am also developing expertise in DevOps and Cloud Operations. With hands-on experience in automation tools like Ansible and exposure to AWS services (EC2, EKS), I aim to leverage these skills in furthering my career in DevOps, Cloud Support, or Linux Administration.
