Metrissianne D. Rivera

Metrissianne D. Rivera serves as a Contract Specialist within the W6QK Acc-orlando office under the Department of the Army, where she plays a pivotal role in acquiring advanced engineering, research, and technical services critical to modernizing military training systems. Her portfolio centers on mission-critical procurements that enhance live-fire simulation infrastructure, mission command capabilities, and aviation and artillery training technologies. Rivera manages the full lifecycle of contract actions—from solicitation and evaluation to award and administration—ensuring alignment with Defense Department innovation priorities and compliance with federal acquisition regulations. She is instrumental in translating operational requirements into executable contract vehicles that support the agency’s mission to sustain and advance U.S. Army readiness through cutting-edge defense technology. Rivera maintains consistent working relationships with a core group of prime contractors, including TORCH RESEARCH, LLC, AMD INTERNATIONAL TECHNOLOGIES LLC, ADVANCED TECHNOLOGY INTERNATIONAL, and FIDELITY TECHNOLOGIES CORPORATION. These partnerships reflect a preference for firms with deep expertise in defense systems integration, modeling and simulation, and technical advisory services. Her contracting approach emphasizes performance-based outcomes, leveraging firm-fixed-price and cost-reimbursement instruments to ensure accountability and mission success. She fosters collaborative vendor engagement, often engaging contractors early in the requirements development phase to promote innovative, cost-effective solutions. While the majority of her acquisitions are conducted without set-asides—reflecting a focus on open competition—Rivera consistently reserves approximately 20% of her portfolio for Total Small Business Set-Asides under FAR 19.5. This demonstrates a deliberate commitment to expanding opportunities for small businesses within the defense technical services sector, though she does not routinely utilize 8(a), HUBZone, or SDVOSB-specific set-asides. Her procurement activity is exclusively focused on NAICS 541990, encompassing all other professional, scientific, and technical services. This includes systems engineering, training system development, digital twin modeling, and operational analysis services that directly support the Army’s next-generation training and readiness objectives.
