About the company
Charles Macdonald, doing business as Mac TECH Solutions, is a sole proprietor based in Oakton, Virginia, that delivers IT support services and Agile development labor to federal agencies exclusively as a subcontractor. The vendor operates entirely within subcontract arrangements — 100% of its recent award footprint consists of sub-awards — and does not hold prime contract authority or IDV positions.
Mac TECH Solutions subcontracts to Salient CRGT, Inc. across four sub-awards totaling $4.2 million in combined obligated dollars. All four sub-awards involve IT support services labor and Agile IT environment support for the Operation Enterprise Data Information Systems (OEDIS) platform, with three awards specifically mandating persistent support for the OEDIS team's enhancements and operations. The awards span two customer agencies: the Department of Commerce US Patent and Trademark Office (three awards) and the Department of Homeland Security US Citizenship and Immigration Services (one award).
All four sub-awards flow through the Alliant II government-wide acquisition contract. Activity has remained flat at two awards per year across 2023 and 2024, with the most recent award dated May 2024. The vendor's capability portfolio, as evidenced by all four sub-awards, centers on labor augmentation and IT support operations rather than software development or system engineering. No specialized SBA designations, set-asides, or federal grant work appear in the source data.
Given the vendor's sole-proprietor structure, absence of prime authority, and concentration on labor-hour subcontracting under a single parent and a single teaming relationship (Salient CRGT), competitive leverage is constrained to task-order volume and labor-rate positioning within Alliant II rather than to vehicle access or prime-contract standing.
