At Randtronics Inc., I designed and implemented kernel-mode and user-mode features for DPM easyCipher, including sparse-file encryption that preserves file sparseness. In the reported use case, this reduced encryption space usage from terabytes to less than 1 MB.

At Thales Group, I architected data discovery and classification integration with Vormetric Encryption, delivering an 8× scalability improvement, and built migration tooling for ProtectFile-to-CipherTrust. Across my work, I’ve developed systems software for Windows and Linux, including file-system minifilters, embedded camera software, and security features.
