About

Enterprise & Solution Architect with 15+ years of experience delivering large-scale cloud, platform, and digital transformation initiatives across Fortune 500 organizations and high-growth companies. I specialize in designing and governing enterprise-scale architectures that connect business strategy with execution—ensuring that target architectures, migration roadmaps, and platform decisions translate into stable delivery and measurable outcomes. My experience spans regulated and high-scale environments across banking, healthcare, e-commerce, and digital platforms. This includes zero-downtime migrations, multi-region platforms, and mission-critical systems serving millions of users. I operate at the intersection of architecture, delivery, and stakeholder alignment, working closely with engineering teams, product leaders, and executives to reduce risk and drive sustainable platform decisions. I also bring a practical focus on applied AI, helping organizations integrate LLM-based capabilities into enterprise architectures securely and efficiently. Since late 2025, I have been operating as an independent consultant and am currently open to senior permanent or contract roles where delivery-oriented architectural leadership and immediate impact are valued.

May 2025 – Nov 2025 · 6 mos · Germany · Hybrid

Owned the end-to-end discovery, architecture, and cross-vendor delivery of a Shopware-to-Shopify Plus e-commerce replatforming across 5 EMEA markets — from initial technical assessment and headless architecture design through to migration strategy, vendor orchestration, and delivery governance.
Designed the target-state headless architecture integrating Shopify Plus, Vue.js/Nuxt.js, Magnolia CMS, and Azure middleware with a zero-downtime migration strategy. Orchestrated delivery across 6 technology vendor teams with CI/CD pipelines (GitOps, Varnish) and structured dependency management across concurrent workstreams.
Defined a 5-market EMEA expansion roadmap through IT Leadership and Business Leadership stakeholder workshops, architecting a multi-tenant governance model for centralized white-label operations with full GDPR compliance.
Led the end-to-end delivery of a Varnish-based full-page caching solution to improve product detail and catalog page performance for the Germany shop — from solution design through production deployment. Facilitated cross-vendor technical workshops to evaluate and finalize the caching architecture, then structured the delivery into JIRA Epics and Stories with clear acceptance criteria. Governed development, testing, and production rollout, and partnered with the QA Lead to define performance testing scenarios, execute benchmarks, and validate results. Achieved 120% improvement in page load performance (sub-2 second loads) — presenting outcomes and business impact to IT and business leadership stakeholders.
