What I'm looking for

I'm targeting Contracts Manager or Subcontracts Manager opportunities.

At Slingshot Aerospace, I lead subcontract strategy, negotiations, awards, and administration for federal defense, commercial, and classified programs. I support a $27M prime program and work with multiple strategic subcontractors on a $70M program.

I develop contracting processes and support agreement automation while coordinating with Legal, Finance, Program Management, Security, and other stakeholders. Previously, at Altamira Technologies, Incorporation, I administered 200+ authorizations to proceed and modifications and negotiated NDAs and teaming agreements.
