I turn data & AI into systems people can actually use.
I build practical AI products, machine-learning workflows and intelligent data experiences — from experimentation and AI workbenches to production-ready applications.

Explore. Build. Explain.
The technical work matters, but so does making the result understandable enough to be useful.
Build
Prototype quickly, connect the real systems and test the architecture hands-on.
Explain
Turn the implementation into a story, demo or guide that others can reuse.
Speaking & live demos
Technology makes more sense when you can see it working.

About
I work where data science, AI and product delivery meet.
In Oracle's OCTO EMEA, I work across Data Science, Machine Learning, AI agents, Oracle AI Database, OCI and APEX — moving between notebooks, architecture, code, demos and the conversations that turn technical possibilities into usable systems.
