Selected
Projects |
· SaaS Analytics, IBM Research (Jun 2008 -
Current) Designed and implemented the prototype for next-gen Business
Intelligence Platform using Software as a Service Model on the cloud
infrastructure like Amazon EC2/S3. BI data servers used were IBM Data
Warehousing Engine (DWE) and Cognos on Amazon Machine Images, to evaluate
issues like multi-tenancy, scale out, ease of management and deployment in
that environment. · Speedy Point in Time (PIT) Recovery in
Databases, IBM Research (Jan 2008 –
Current) Working on a prototype of a smart storage controller that is
more aware of database objects and their physical layout on devices to
eliminate redundant backup images used for PIT recovery. · IBM Infosphere Mashuphub, IBM Research (Jan
2006 – May 2008) Designed and Implemented a server side mashup platform to do
light-weight Extract Transform and Publish (ETP) using Web 2.0 technologies.
This platform was released as a Product called IBM Infosphere mashuphub in 2nd
quarter of 2008. · DB2 XML, IBM Research (Dec 2003 – Dec 2005) Designed and
implemented and performance tested the XQuery and XML navigations in DB2
engine. I was the component owner for code generation and XML Navigation
components in DB2 XML. · Query Sampling in DB2, IBM Research (Dec 2001 –
Nov 2003) Designed implemented and patented the query sampling in DB2 engine.
I modified the DB2 kernel execution model for symmetric multi processor
(SMP/Intra Query) parallelism for sampling to be repeatable. I also worked
with the standards to get TABLESAMPLE clause included in SQL 92 standards. · Optimizer hints in DB2, IBM Research (Dec 2001
– Nov 2003) Designed and implemented a prototype to provide query hints to the
optimizer in DB2. · Online aggregation and continuous query, IBM
Research (Jan 1999 – Nov 2001) Designed and implemented a prototype in
DB2 to perform online aggregation to provide approximate answers to business
intelligence queries by computing running estimates and confidence intervals
from sampled data. ·

Patents |
· Efficient
sampling of a relational database (US Patent 6993516) · Method
and apparatus for using Java as a stored procedure language and as an
embedded language on a client (US Patent 6477540 ) · Method
for monitoring dependent metric streams for anomalies (Filed) · Method
and System for Integrating Information from Data Feeds (Filed) ·
Nested Navigations for XPath/XQuery Evaluation
(Filed). |
