Who am I?

I'm Nebo — a husband, father, and builder at heart. Outside of family time you'll find me playing soccer and tennis or working on a project, and professionally I'm a Data Engineering Manager at Meta, living in Oakland. I love doing things that have a real impact.

Data Engineering in the Agent Era — as AI agents become consumers of enterprise data, the scarce skill is making data machines can understand, trust, and act on: build the data foundation, encode the meaning in a semantic layer, and evaluate the behavior.

On Property Taxes — what started as my own property tax appeal became a countywide analysis of Alameda County assessments: Proposition 13 protects longtime owners as designed, but peak-era buyers are being taxed on value the market took away. Includes three things the county should do about it. All writing.
