Bridging the Gap Between Leadership and Execution:

For Series A-C tech companies, scaling often creates a bottleneck between technical realities and business goals. As an embedded Fractional Technical Chief of Staff, I don't just deliver strategy decks; I build the operational infrastructure that makes your vision real.

I act as an organizational multiplier—translating complex engineering constraints into clear business priorities and unblocking organizational momentum. You get the strategic execution of a dedicated right-hand operator, structured flexibly for your current stage of growth.

Where I Operate:

I partner with founders, CEOs, and CTOs who are personally bottlenecked by cross-functional execution. I am domain-agnostic, but provide exceptional leverage in:

Hardware & Software Ecosystems

Navigating the complex intersections where physical engineering constraints meet software development timelines.

Growth-Stage Tech

Stepping in during critical trigger events such as new funding rounds, rapid team scaling, and major product bets.

Cross-Functional Alignment

Serving as the bridge between engineering, product, and business teams to ensure that what leadership decides is flawlessly executed across the organization.

The Operator Advantage:

Most operations consultants cannot read an engineering sprint, and most engineers do not want to manage cross-departmental alignment. I do both.

With a BS and MS in Electrical Engineering and an MBA, my background spans safety-critical aerospace systems, global platform modernization, and scaling tech platforms. I have successfully managed $200M+ global programs and aligned dozens of departments without formal authority.

I combine this deep technical literacy with advanced AI fluency—utilizing custom automations and large language models as a force multiplier to process research, synthesize data, and build operational infrastructure faster than traditional operators.
