What I'm looking for

I'm targeting fully remote global roles in Linux engineering, cloud operations, and DevOps.

At Aforserve.com Ltd, I administer Linux application, database, and backup servers for enterprise clients while maintaining a 99%+ uptime SLA. I troubleshoot production incidents and deploy hotfixes and emergency patches on live systems with zero unplanned downtime.

Earlier, I deployed applications on AWS EC2 and S3, configured Route53 DNS, and installed Ansible at HighSky IT Solutions. I also built a Python cryptography CLI using AES and RSA, and I'm RHCSA certified.
