SUMMARY OF EXPERIENCE

Confidential

SAS Alliance Partner

• Built, configured and maintained OpenLDAP software for authentication and authorization of thousands of users using green high performance cloud computing cluster.
• Built, configured and led the administration and development of predictive analytics environment with SAS 9.3 platform using Enterprise Miner 7.1, Model Manager 3.1, SAS Forecast Server, and In-Database Teradata running scoring models.
• Built and optimized SAS 9.2 Web infrastructure for EBI prod/dev/test distributed environments.
• Developed a system for performance analysis and SAS workload management for a large number of Linux nodes running different SAS logical servers.
• : Designed and developed SAS Bulk Loader of RDBMS data -- automated system for monthly builds of SAS data marts from Oracle EDW dumps. The system parses corresponding DDL files and generates SAS 9.2 Data and Proc steps and Macro code to read flat-delimited-compressed data files and populates any format of SAS library or SAS/SPDS library with dynamic cluster tables in SAS/SPDS server.
• T Built SAS data warehouse for efficient processing of Medicare part A/B/D data to evaluate variability of health services across different US geographical regions.
• Deployed and customized entire SAS/EBI/EDI suite on IBM P570 AIX partitions dedicated to DEV/TEST/PROD environments to implement change control and change management processes. Developed Perl parser/post-processor that splits SAS/DI studio generated code into data independent code and SAS autoexec code with all data definitions that run SAS production jobs under IBM ESP scheduling system.

• IRS: Developed an application using SAS system for processing gargantuan amount of data and reliably loading it into Oracle using bulk loader sqlldr with SAS generated custom control and data files. Also implemented a set of instrumentation routines using SAS and Perl for performance and capacity planning of Sun Fire E25K server that this production system runs on.
• Deployed and administered entire SAS/EBI platform on Solaris 10. Developed a framework for automated stopping and re-starting in proper sequence of all 20 platform's servers monitoring all servers and open SAS clients' sessions and their corresponding workspaces, activity logging and other real time system activity. The framework is developed using Perl and SAS Open Metadata Interface to obtain data dynamically from the SAS metadata server repositories. Led the development of turn-key Customer Relationship Management CRM system to manage relationship between VC and very large Internet betting community.
• Built and configured OpenLDAP server on a Linux system. Designed and built LDAP directory to be used for user's authentication and authorization for very large hierarchical organization. Wrote a parser to convert the LDIF file into SAS metadata canonical tables and to import them into SAS metadata server. Designed and developed analysis and reporting system processing data from several very large Oracle instances at the
• U Upgraded ten large AIX, Solaris and HP-UX servers running SAS 8.2 to SAS 9.1.4 system. Built and configured two SAS/EBI servers for consolidation of the SAS enterprise applications to run in this distributed environment. Defined all instances of Oracle, DB2, and ODBC in the SAS Metadata Server that is used by SAS users running Enterprise Guide 4.1. Built a set of stored processes defined in SAS Information Delivery Portal for use with SAS Web Report Studio and Report Viewer.
• Installed and configured very large SAS/EBI server running on several UNIX systems. Implemented security infrastructure for the SAS Web Information Delivery Portal utilizing WebSeal WebLogic SAS WIK secure single sign-on. Also instrumented all of SAS client applications and server communication over SSH tunneling. SAS metadata server authorization along different authentication providers is deployed for external and internal users/applications.
• Designed and developed large ETL system to extract voluminous data from Teradata, transform within SAS warehouse and load it into Oracle RDBMS. Designed and coded a set of SAS macros that control the flow and execution of the ETL process based on a large matrix of business parameters.
• Designed and developed SAS datamart used for credit risk analysis, scorecard and forecast modeling. The datamart consists of several SAS Libraries with additional metadata for automatic validation of analysis and reporting procedures manipulating this data.
• Developed a hedge fund trading software system. The system encompasses reliable acquisition and management of Bloomberg market data, quantitative models to predict performance of different financial instruments, automated back testing of trading models and signal generation for portfolio allocation. System is implemented using the SAS system, Perl, MATLAB, Excel and RDBMS on Linux and Windows platforms.

System Administrator/Developer

• Built and supported an enterprise-wide system management server that houses and distributes all system and name spaces information for a large distributed UNIX environment. Major components of this system include Ingres database, Kerberos server, DNS server, and file distribution to every domain's NIS/NFS server.
• Compiled, installed and configured numerous Internet freeware for multiple UNIX platforms. Some of these tools include: Rsync, RCS, CVS, dig, s-trace, lsof, nfswatch, Solaris SE Toolkit. Integrated these products into a centrally managed ubiquitous distributed file system.
• Responsible for implementation and operation of the enterprise distributed backup and disaster recovery system for over 2000 Sun systems based on Legato NetWorker software.
