To design and implement the sexiest systems.
- 2002 - Microsoft
XDegrees merged with another company, but their ticker symbol is still MSFT.
We are now working with the Core File Systems group.
- 2000 - 2002 XDegrees:
As a first employee bootstrapped the software development.
Assumed leadership roles in the design and implementation of a
system for scalable peer-to-peer resource
sharing including an extensible resource naming service, together with
SOAP and WebDAV extensions of HTTP server and proxy interfaces.
Co-author of two pending patents on
the naming system protocols and its security aspects.
- 1998 - 2000 Kestrel Institute:
Designed and implemented a bootstrapped
specification based-program transformation
system for an algebraic/functional language using polymorphic
types and reflection.
Participated in DARPA and NSA sponsored projects on
program transformation, integration of verification systems,
design of embedded systems, and high performance knowledge bases.
Took on existing programs and assumed leadership responsibilities,
was awarded new contracts on embedded system design.

DISSERTATION:Integration of Decision Procedures in Temporal
Verification. Thesis advisor: Professor Zohar Manna.
proposes novel algorithms for resolving constraints on data-types that are
commonly used in software and hardware. A powerful framework allowing modular
and efficient integration with expressive extensions is used to glue the various
components. The algorithms are used for establishing temporal properties (time
dependent) of concurrent, reactive, and hybrid systems. The procedures are
part of STeP (Stanford Temporal Prover:
in well over 100,000 lines academic strength C, ML and Java. STeP has been
distributed in around 150 licensed copies in industry and academia.
