About the company
Mkgcs, LLC (doing business as Michael Karagiannis Govt Consulting Services), a Herndon, Virginia-based LLC founded in 2002, delivers custom software development, enterprise systems engineering, and IT modernization services to the Department of Defense as a prime contractor on the GSA Multiple Award Schedule and the One Acquisition Solution for Integrated Services (OASIS) vehicle, and as a software-development subcontractor to Booz Allen Hamilton on defense training-readiness and capability-threat programs. The vendor operates in full-and-open competition rather than under set-asides, though recent prime work includes a Total Small Business set-aside delivery order awarded in June 2026.
Mkgcs maintains narrow customer concentration within defense. The Department of the Air Force Headquarters District Washington accounts for four awards with $24.1 million combined potential value — representing roughly 72% of the vendor's total $33.4 million combined potential value across all recent awards — with the Department of the Army Forces Command (16 awards) dominating award count but carrying substantially lower per-order magnitude. The Navy, OSD, and GSA round out the active customer set. The vendor works primarily through two federal vehicles: the One Acquisition Solution for Integrated Services GWAC, which carries 16 task orders, and the GSA Multiple Award Schedule, which carries seven task orders worth $24.5 million in combined potential value. Representative recent prime work includes a $2.47 million Total Small Business delivery order from District Washington for TIMES 2.5 system sustainment (June 2026, ultimate completion June 2027) and a $1.86 million non-set-aside delivery order for TIMES Bridge support (July 2025, completed June 2026).
The vendor's capability portfolio centers on custom software engineering for military systems platforms. On its GSA Schedule, Mkgcs offers thirteen active labor categories spanning software engineers, IT certified professionals, technical writers, enterprise architects, and data scientists, with hourly rates from $89.61 (Associate Software Engineer with technical certification) to $246.18 (Lead Enterprise Architect with master's degree and twelve years experience). No cleared positions are offered. NAICS concentration skews toward Engineering Services (18 awards) and Custom Computer Programming Services (9 awards), with PSC work split among IT Strategy and Architecture, Professional Support (Other), and Management Support (Other).
Subcontract footprint is substantial and concentrated. Booz Allen Hamilton anchors the vendor's sub work, with seventeen visible Emergent Threat Training and Readiness Capability (ET2RC) custom software development and subject-matter-expertise sub awards dating from December 2022 through January 2025. Additionally, Mkgcs subcontracts to National Center For Manufacturing Sciences on a Medical Resource Planning, Sustainment and Synchronization Phase II grant sub-award (November 2023). The vendor's sub work represents 58% of its recent award count (18 of 31 awards), indicating material reliance on teaming revenue alongside prime delivery-order work.
Activity peaked in 2024 (nine awards) and has decelerated (three awards in 2025, one in 2026 year-to-date). One award with $2.5 million combined potential value reaches ultimate completion within the next twenty-four months, presenting minimal near-term recompete exposure. The combined dollars obligated across all awards ($74.8 million) exceed the combined potential value ($33.4 million) by 224%, reflecting maturation of older contracts beyond their ceiling values or resolution of contract modifications not yet reflected in source potential-value figures.
