How I work

Public services

Experience with management systems, healthcare and municipal operations. Institutional context matters as much as implementation.

Data for decisions

Integration and automation

Connecting tools and workflows, with attention to contracts, errors and integration boundaries.

Technology leadership

Coordinating teams, setting priorities and deciding what to build, what to integrate and how to support adoption.

Applied AI and experimentation

I work with model integration, tools and agent systems, keeping experimentation, ongoing development and validated features distinct.

Creative engineering

I also work with interaction, visual systems and 3D visualization, from an audiovisual 2048 adaptation to cross-platform themes and modeling.
