epinova corp. Somerville, MA Jan 2002 to Sep 2006
President
Created Structs And Nodes Development methodology (SAND) whitepaper and started the SandBoss open source project to demonstrate the technology. Advantages of SAND included single point data definition, verb oriented messaging architecture, field level authorization granularity, simple transaction support, clear interfaces for supporting technologies, application tuned caching, generated documentation, and support for large scale code generation integrated into a dependency tracking build process. Unlike most one-shot code generators, SAND was designed for continuous use, regenerating code as needed in response to changes. Continuous code generation resulted in high accuracy reduced effort development. All rights for SAND were transferred to SAND Services Inc. which was formed to commercialize the technology.
