Fractional Engineering Executive · I help B2B SaaS companies unblock revenue through engineering

I'm a fractional Engineering Executive with 13+ years leading engineering organizations across B2B SaaS — scaling teams, rebuilding delivery systems, and aligning engineering with the outcomes the business needs.

I step in when growth has created more demand on engineering than current systems and structures can absorb. As an embedded executive, I work with your existing leaders to build the execution systems, org structures, and cross-functional alignment that make predictable delivery possible.

Proof:

Scaled a platform org from 5 to 70+ engineers, cut integration delivery time from ~6 months to ~3 weeks, and reduced a critical backlog from 35+ issues to single digits in 4 months.
