Project Name: IPCF provisioning tool

Role: Senior software engineer

Project Description: IPCF provisioning tool is developed for Starent's

ST16/ST40 router embedded system. It allows operator to set/get various

data plans, policies and subscribers. It is a 3-tier system which contains

client - UI tool where actual provisioning is done, middle-tier server that

accepts requests from client and converts to that understood by backend

server, backend server - it include IPCF (Starent's boxer) and SSC server

this is where the actual dynamic rules are applied. UI tool is very

intuitive where you can create dynamic policies in the form of if-else, and

other programming operations. Middle-tier has to convert the policy to CLI

format for set policy operation and convert cli format to UI format for get

policy profile. UI is developed in Smart Google webtool kit (java

libraries), middle tier is server is written in python top of django

framework. Interface between client and middle-tier server is xml over

http. Interface middle-tier server and IPCF is xml over CORBA and with SSC

interfae is XML RPC.

Responsibilities/Accomplishments:

. Proof of concept just the UI part was developed in Flex.

. Design of complete UI framework in smart GWT (Java). Development

of initial UI framework and support for Login/logout, IPCF

configuration, SSC configuration, session handling, change

password, policy configuration.

. Design of middle tier server that includes Django framework.

. Development and support at server side for following modules -

login, logout, session handling, ipcf configuration, ssc

configuration, policy configuration.

. Design of developing logic to convert UI format to CLI format and

CLI format to UI.

. Creating sequence diagrams for complete end-to-end interfaces.

. XML RPC communication for some methods with SSC.

. Design test framework using Django test client.

. Unit Testing, Bugs resolution and End User Product Documentation.

. This product is very evolving which required constant design

changes.

. Customer Requirement gathering.

. Assist customers / vendors / support organizations in

troubleshooting various Remedy tickets

Project Name: Yahoo Apex Data systems

Role: Senior Software Engineer

Project Description: A cutting-edge platform that simplifies the process

for advertisers when buying targeted, guaranteed, and non-guaranteed

advertising inventory across Yahoo's owned and operated network, partner

sites, and other advertising networks. The platform will allow advertisers

to plan, preview and submit single orders targeted across the network of

Yahoo publisher partners. All the data for advertisements and publishers of

Yahoo are stored on warehouse. Each customer has a requirement to store

their data in specific format. Data is received from different sources in

the form of events and then parsed by the transformer; this data is stored

in warehouse. Customers would request for different reports that are to be

generated from real-time pipeline, this data is often fed to customer

related reporting tools.

Responsibilities/Accomplishments:

. Developed a data generation infrastructure that simulated real-time

revenue traffic and helped functional, integration and performance

testing of the data pipeline.

. Worked on the source control, build, installation and deployment

framework for the project. Also helped with end-to-end integration

testing of the pipeline.

. Involved in the design, development and maintenance of the real

time monitoring framework for the production pipeline.

. Writing Myna sql queries.

. Design and develop user defined function in C++

. Developing tools that would speed up processing of reports that are

generated.

. Developing tools for monitoring the pipeline.

Client: Mirapoint Inc (Persistent system ltd)

Nov, 2004 - Dec, 2007

Project Name: Email messaging system

Role: Senior Software Engineer

Project Description: Mirapoint is into Secure Email messaging domain. They

have the only appliance based Mail Servers in the market. They also have a

range of associated security products such as 'Razorgate' which helps

accomplish Anti Spam, Anti Virus and Junk Mail Management filtering.

Sub-project: Real time billing daemon project (Multi threaded applicaiton)

This is a real time billing system that charges mobile users for sending

and receiving mail. This is standalone process that communicates with

Mirapoint messaging server and Logica CMG system's billing library. For

every message that is sent/received via Mirapoint server, Mirapoint server

will send information on RTBD protocol to RTBD process, RTBD process will

do prerequisite, talk to logica CMG billing libraries depending on whether

the user is prepaid or postpaid and sends response back to server. This is

multi-threaded real time application. It also sends SNMP events to SNMP

master agent. Development was done in 3 phases -

Phase 1: Debiting a user for every delivery (SMTP) of mail.

Phase 2: Debiting a user for retrieval (IMAP) of mail.

Phase 3: Account retrieval of a user when he/she sends/retrieve a mail via

SMTP/IMAP and replace his mail ID with that retrieved from LDAP. It also

involved writing a SNMP subagent.

Responsibilities/Accomplishments:

. Design and development of RTBD protocol.

. Design and development of RTBD multi thread process

. Development of LDAP communication for user account retrieval

. Development at SMTP side for RTBD protocol support

. Development of IMAP proxy side for RTBD protocol support.

. Support RTBD CLI commands on Mirapoint server.

. Communication with SNMP master agent, development of SNMP sub-

agent.

. Writing unit test cases and framework for the same.

Environment / Languages: C, multi threaded programming, td scripts, Shell

Script, socket programming, Redhat enterprise edition and FreeBSD.

Sub-project: 3 tier shared folders (Distributed system)

It is way for users to access their folders for more than Mirapoint

servers. It also allows users to access the folders that are shared across

multiple Mirapoint servers. Single master, multiple slave models. Master

updates, maintains and keep tracks of shared folders. Slave talks to master

to publish shared folder and retrieve updates of other mas machine shared

folders. Interface between master and slave was GULP protocol

Responsibilities/Accomplishments:

. Single handedly designed and developed entire 3tsf project.

. Got employee award for best design.

. Developed authentication mechanism between master and slave.

Project Name: Managed Security

Services

Role: Software engineer

Project Descriptions: This Project is part of the largest hybrid wireless-

wired network in India, being established in the University of Pune Campus

by CINS (Center for Information and Network Security) in collaboration with

Network Security Solutions (India) Pune. This project involves secure wired

and wireless implementation, development of tools and techniques to protect

University wide network from intrusion.

This project-involved development of an integrated solution for different

security devices (hardware/software) like IDS, firewalls, vulnerability

scanners, audit logs from mail servers, web servers, etc. Through this

product any MSS provider can remotely manage security form their SOC

(Security Operating Center). This product collect logs from Intrusion

detection system, firewalls, application logs (web server, proxy server,

mail server, Windows NT security logs, UNIX system audit logs) then

normalize log information in a common format. It detects Intrusion

signatures and abnormality from logs and generates alerts. The collected

information is correlated and normalized alerts are then sent to SOC.

Security consultants then take necessary actions from SOC center

Responsibilities/Accomplishments:

. Design and development of various log parsers for the devices.

. Design and development of Aggregation algorithm (a patent was filed

for the same).

. Writing modules to store parsed data to database.
