Aaron J. Lewis

Aaron J. Lewis serves as a key procurement professional within the Internal Revenue Service, supporting the agency’s mission to modernize tax administration through secure, technology-driven solutions. He manages a diverse portfolio of acquisitions focused on custom software development, data analytics platforms, and cybersecurity infrastructure, ensuring compliance with federal IT modernization mandates. His work directly enables the IRS to enhance taxpayer services, automate compliance workflows, and safeguard sensitive financial data across hybrid cloud and on-premises environments. Lewis specializes in complex, performance-based contracts requiring rigorous technical evaluation and risk mitigation, often coordinating with enterprise architecture and cybersecurity teams to align procurement outcomes with strategic digital transformation goals. Lewis maintains strong, long-term relationships with leading federal contractors including Deloitte Consulting LLP, Science Applications International Corporation, Maximus Federal Services, Cherokee Nation Federal Consulting, and InsySCO, Inc. These partnerships reflect a preference for established vendors with proven capabilities in federal tax systems, cloud migration, and mission-critical application development. His contracting patterns emphasize performance outcomes over purely transactional deliverables, fostering collaborative, risk-sharing arrangements that prioritize system resilience and continuous improvement. His procurement strategy prioritizes open competition, with 80% of awards issued without set-asides, while maintaining a consistent 20% commitment to socioeconomic programs—10% through 8(a) competed contracts and 10% through total small business set-asides under FAR 19.5. This balanced approach ensures broad market access while supporting disadvantaged and small business participation in high-impact technology initiatives. Lewis’s primary procurement focus lies in NAICS 541511 (Custom Computer Programming Services) and 541519 (Other Computer-Related Services), with significant activity in 541690 (Scientific and Technical Consulting). He routinely acquires enterprise software development, data integration tools, AI-driven fraud detection systems, and cloud-based compliance automation platforms, demonstrating deep expertise in federal IT modernization and secure digital service delivery.
