About the company
Ddao, LLC, a minority-owned, self-certified small disadvantaged business based in McLean, Virginia, operates exclusively as a subcontractor providing technical engineering support services to federal customers, with no prime contract footprint in recent awards. The company is structured as an Asian-Pacific American-owned limited liability corporation competing in Computer Systems Design Services (NAICS 541512).
Ddao's federal work to date consists entirely of three subcontract awards under ECS Federal, LLC as prime contractor, all issued through the Alliant II GWAC between July 2025 and March 2026. The work flows to the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency (CISA) under the TECHNICAL ENGINEERING SUPPORT SERVICES (TESS) award vehicle. Two awards, dated July 2025 and August 2025, funded subcontractor labor; a third award dated March 2026 obligated Distributed Environment (DE) funding. Combined obligated value across all three awards totals $821 thousand.
Activity is nascent — two awards in 2025 and one in 2026 — with the vendor carrying no pipeline visibility or recompete cliff in the source data. The entire customer base is CISA; vendor concentration on a single customer and single prime (ECS Federal) and single parent vehicle (Alliant II) reflects a highly dependent relationship at present. Ddao's capability positioning appears narrowly scoped to labor provision within ECS Federal's TESS delivery under the Alliant II contract. The vendor's recent award density and dollar magnitude do not yet signal meaningful federal revenue or competitive footprint; the relationship is emerging and sub-scale.
