Summary

Innovative, hands-on AEM Solutions Architect with over 15 years of experience delivering complex, scalable CMS platforms and digital ecosystems. Specialized in Adobe Experience Manager (AEM) architecture, development, business analysis, requirements engineering and migration (exit) strategies — with a strong focus on integrating cutting-edge AI technologies and implementing robust web security frameworks, and enabling data-driven marketing and personalization strategies within AEM.

Combining deep full-stack development expertise with a strategic mindset, I design and implement high-performance, cloud-ready AEM applications that comply with modern security standards (OWASP, GDPR, WCAG) and support personalized, data-driven user experiences.

I design and deliver enterprise-grade AEM solutions across sectors like telecom, finance, and government — with a strong focus on performance, scalability, and business value. My core mission is to elevate AEM with AI: by integrating technologies like LangChain, FastAPI, OpenAI, Hugging Face, vector databases (Pinecone, FAISS) and Google Cloud’s Vertex AI platform, I turn static CMS platforms into intelligent, personalized content engines. Security is built-in — through OWASP-compliant development, WAF integration, and proactive vulnerability management.
