What I'm looking for

I seek a role where I can author developer-focused documentation, lead Docs-as-Code initiatives, collaborate with engineering/product teams, and leverage AI and IA to improve content quality and developer experience.

I am a Senior Technical Writer with extensive experience producing developer and user-facing documentation across payments, financial switch systems, and aerospace manuals. I collaborate closely with product and engineering teams to produce accurate, scalable documentation, applying Docs-as-Code practices, information architecture principles, and AI-assisted workflows to improve quality and efficiency.

My work includes API and integration guides, deployment and installation documentation, compliance-driven materials, and structured authoring using DITA and Markdown. I have led documentation efforts, managed repositories and client portals, conducted peer reviews, and migrated legacy content while maintaining standards and producing diagrams and test-validated workflows.
