He values humility, collaboration, and clear communication, and fosters an environment where autonomy is encouraged and supported through impactful projects.

• Technical Leadership: Track record of influencing technical direction and mentoring engineering teams, with excellent communication skills to articulate technical vision to diverse stakeholders.
