What I'm looking for

I’m eager to contribute my security architecture expertise and DevSecOps leadership to a forward-thinking organization, driving secure innovation and compliance within complex, multi-stakeholder environments.

At TECHNITY, I designed and operated secure AWS environments with Terraform and Terragrunt, and migrated staging infrastructure from manually managed resources to reproducible infrastructure as code. I also implemented deployment pipelines with approval gates and OIDC-based AWS authentication.

At AVAELGO and TECHNITY, I’ve worked on security architecture, threat modelling, and embedding security controls into CI/CD workflows. My work includes SLSA Level 2 supply-chain practices such as SBOM generation, artifact signing, and provenance attestations.

At ESCHBACH, I led a secure migration from legacy Atlassian tools to Microsoft Azure DevOps for an organization of over 100 developers. I’m eager to bring my security architecture expertise and DevSecOps leadership to a forward-thinking organization working on secure innovation and compliance in complex environments.
