PROFESSIONAL EXPERIENCE:

Confidential, Palo Alto

Sr. Member of Technical Staff

Responsibilities:

• Participated in architecture design and implementation of a vSphere plug in, Storage Virtual Appliance (SVA) management system, to create and manage a virtualized, clustered, highly-available, ISCSI SAN from the internal storage, provided by multiple servers, each runs ESX and the SVA virtual machine (VM).
• Implemented SVA management system installation, registration and configuration.
• Implemented SVA highly available cluster configuration and creation.
• Implemented deployment process as Java future tasks to import SVA virtual machine on each ESX host from a SVA .ovf file and update the job progress to the Flex client in real time.
• Implemented the messaging service by using JMS for message delivery from the publishers (SVA VMs) to the subscribers (SVA management service).
• Implemented network configuration management by invoking WIN APIs through jna (Java Native Access).
• Participated in network design and configuration for VMs and ESX hosts inside SVA cluster.
• Designed and implemented host auditing process to select the candidate servers to be added into SVA cluster.
• Participated in system failure detection, restore and rollback mechanisms design and implementation.

Confidential, Santa Clara

Sr. Software Engineer

Responsibilities:

• Responsible for the design, documentation and implementation of Active-active cluster support by using Java and cluster APIs in C++.
• Provided business logic to Java server to implement load balancing by round-robin, support namespace synchronization and communication among nodes by using JBoss remote call Java libraries.
• Implemented a Namespace server (NS) that provides a global namespace that appears as a single file system to all clients from all geographic sites using Java and C++. The main technologies used are Microsoft DFS and Microsoft Server Cluster.
• Participated in the design and implementation of the system using the active-passive cluster technology.
• Implemented snapshot support for aggregated shared volumes.
• Created and managed backend NAS snapshot by using standard WMI APIs in C#
• Implemented the snapshot management dialog in GUI by using Java Swing.
• Implemented snapshot support in Java server by integrating the calls to C# provider through XML-RPC and handling client requests from GUI through RMI
• Developed a provider to manage Data Domain backend NAS device by using SSH Java libraries.

Software Engineer

Confidential

Responsibilities:

• Implemented XML-RPC tunneling mechanism to bridge Java server with its C# and C++ providers by using XML-RPC Java libraries and XML-RPC C++ classes.
• Developed providers to manage Windows file servers (by WMI) and NetApp filers (by their ONTAP APIs).
• Provided Java server the server side business logic which manages the fileserver providers and the data the providers collect.
• Provided Java server the business logic to assemble the fileservers’ volumes into volume sets (virtualized aggregated storage) with rules that govern how (and if) information is written to them.
• Implemented system database by using Sleepycat Java libraries.
• Developed statistics component that
• Gathers performance data from backend NAS devices by calling WMI APIs in C# or by querying SNMP MIBs by the Java libraries
• Stores statistic data in a log file by using log4j
• Implemented statistic management dialog to configure and select statistic data shown in a table in GUI by Java swing
• Generates statistic xml report per user specified time period, data servers or volumes
• Implemented schedulable jobs to process various requests during data migration as well as a report generation mechanism to put job result into a XML file in the Java server.
• Implemented a code generation process for localization which ties the IDs to the localized strings, and a mechanism to retrieve the strings; this is used extensively in alarms and server exceptions thrown back to the client.
• Participated in implemented a new server by using Hibernate and HSQL as system database
• Contributed to the GUI Client which is a Java application/Applet developed with Swing components interacting with the server through RMI
• Developed infrastructure for GUI client, handling messages from the server, and directing messages appropriately to and from dialog screens and the main views.
• Developed a GUI library which extends and simplifies Swing components allowing greater re-use across the GUI client.
• Designed and implemented end to end functionality from server to GUI client: file system statistics, file server discovery, volumeset management, job scheduling etc.
