Professional background
Technical leadership grounded in implementation
I have spent more than fifteen years building and modernizing enterprise applications, from Java and Spring platforms to Angular experiences and event-driven integrations. My strongest contribution is connecting architecture decisions to the code, delivery practices and operational realities that make systems sustainable.
Today, I extend that foundation with enterprise AI patterns—including document processing, model evaluation, RAG and agent workflows—while keeping security, traceability and human validation central to the solution.
