Domain experts who build software and AI

Deosi was founded in 2008 in Vienna, Virginia to solve data-sharing problems inside DHS programs. That work grew into Veterans research, public health and connected diagnostics, AI agents for healthcare operations and our own AI products.

How we work

Every engagement is led from Vienna, Virginia by the people who architect it and answer for it. Our global delivery center in Noida, India adds engineering capacity where the work allows it, so programs get senior US leadership and a team that keeps moving around the clock.

Global delivery model

Onshore leadership. Global engineering. One team.

Architecture, security and customer-facing roles stay in the US. Build, test and support scale through Noida, India, on the same tools, standards and release process.
