What I'm looking for

I’m looking for a role where I can architect and secure cloud platforms from the ground up—owning CI/CD and automation, strengthening IAM and API security, and delivering production-grade security operations with measurable reliability and maintainability.

I’m a DevOps engineer with 4+ years delivering automation, CI/CD pipelines, and security operations solutions across enterprise environments at Pfizer and Stryker. I rebuild legacy workflows into production-grade systems, standardizing Dev/Stage/Prod to reduce risk and deployment bottlenecks.

I rebuilt CI/CD pipelines using GitHub Actions and AWS SAM/CloudFormation, and I owned Python-based automation pipelines in Cortex XSOAR for a monorepo and a dedicated XSOAR repository. I also modernized a legacy automation server—auditing and purging 152 obsolete scripts and migrating 108 scripts from Python 2 to Python 3 to restore maintainability.

I focus on secure-by-design platforms and automation that teams can actually run. From Cortex XSOAR integrations and custom Splunk/Cribl tooling to evaluating Ansible Automation Platform (AAP) for internal self-service automation, I mentor engineers, support on-call coverage through Engineer-on-Duty rotations, and bring clarity through technical documentation.
