What I bring to the work.

My background
01

Engineering foundations

My background is in software engineering and engineering management. I build with code, data, and automation, from lead routing to internal tools.

02

Hands-on growth experience

I’ve run campaigns, worked on funnels, and managed acquisition budgets. I know the questions teams need their data and tools to answer.

03

A founder’s mindset

I built an agency serving 600+ clients. That experience taught me to spot opportunities, make tradeoffs, and take responsibility for the result.

A few results along the way.
