Engaged through Xebia to modernize WordPress templates across Levi Strauss & Co. web properties.

• Modernized legacy WordPress templates and PHP functions, cleaning up sloppy patterns and unifying template structure for maintainability.
• Restored editorial agility by exposing user-facing fields through existing Advanced Custom Fields (ACF), so content teams could ship copy / image / metadata changes without engineering review.
• Layered on technical SEO improvements (structured data, schema markup, semantic HTML, sitemap hygiene).
• Added LLM / answer-engine discoverability (llms.txt-class metadata, JSON-LD entities) — positioning the Levi's web surface for AI-driven search before it became the default channel.
• Worked inside an enterprise change-management and review process; shipped through Xebia's delivery pipeline.

Operating WordPress + full-stack agency serving Fortune 500, regulated-industry, and high-growth clients.
