Adanna Ezeala-Harrison

Adanna Ezeala-Harrison serves as a key procurement professional within the National Office of the Internal Revenue Service, supporting the agency’s mission to modernize federal tax administration through advanced technology solutions. She manages the acquisition of custom computer programming services critical to legacy system modernization, cloud migration initiatives, and cybersecurity enhancements. Her work directly enables the IRS to transition from outdated COBOL-based environments to secure, scalable, and interoperable digital platforms, ensuring compliance, efficiency, and taxpayer service improvements. She typically oversees full lifecycle contract actions for software development, systems integration, and analytical support services under competitive and sole-source authorities as needed. Her contractor relationships are primarily with firms specializing in enterprise software modernization, cloud-native development, and federal cybersecurity compliance. She engages with a broad spectrum of vendors, including large systems integrators and niche technology providers with deep expertise in IRS-specific tax processing environments. Her procurement approach emphasizes technical proficiency, risk mitigation, and adherence to federal IT modernization standards, fostering partnerships with vendors capable of delivering secure, auditable, and scalable solutions in highly regulated environments. Adanna maintains a strong preference for open, non-set-aside competitions, with 100% of her acquisitions conducted under unrestricted solicitations. While she does not prioritize socioeconomic set-asides such as 8(a), HUBZone, or SDVOSB programs, her contracting decisions are driven by technical capability and mission alignment rather than socioeconomic criteria. This reflects the IRS National Office’s focus on rapid delivery of high-impact, mission-critical systems where specialized expertise outweighs socioeconomic preferences. Her primary procurement focus is on NAICS 541511 (Custom Computer Programming Services), with deep specialization in legacy system modernization, cloud migration, vulnerability scanning, and secure application development. She procures services that support the redesign of core tax processing infrastructure, including API-driven interfaces, data analytics platforms, and automated compliance tools—all critical to the IRS’s digital transformation strategy.
