LIGHTFEATHER IO LLC

LightFeather IO LLC is a digital services company founded in 2018 that modernizes U.S. federal infrastructure through DevSecOps implementation, cloud engineering, and legacy system transformation. Operating as both a Woman-Owned and Service-Disabled Veteran-Owned Small Business, the company works exclusively with federal agencies to deliver value-driven IT solutions that integrate security practices directly into development and operations workflows. The company's technical practice centers on three core service areas: DevSecOps integration for federal systems, cloud-based infrastructure modernization, and comprehensive system transformation projects. LightFeather positions itself at the intersection of cutting-edge cloud technologies and the specific compliance, security, and operational requirements of government IT environments. Their approach combines forward-leaning methodologies with the technical rigor required for federal work, where security isn't an afterthought but a foundational element of every deployment. Led by CEO Sarah Fahden, LightFeather maintains a mission-driven operational philosophy that technology should serve people rather than create barriers. The company explicitly frames its work around making government services more effective for end users - citizens who depend on federal systems to function reliably and securely. For security professionals, this translates to work that matters beyond abstract compliance: modernizing infrastructure that serves real public needs while meeting stringent federal security standards and advancing the maturity of DevSecOps practices across government agencies.
