PubMatic

Audience Insight

Description: PubMatic's Audience Insight can help publishers learn more about their target audiences,

including aggregated information about impression, eCPM, segments, unique users and more.

This information is aggregated on different slicing and dicing dimensions of media buyers.

Developed dataflow pipeline to aggregate ad-serving impression on daily and monthly basis

to provide audience insight against media buyer on impression count, eCPM, unique users

count and more.

Key Responsibility Areas

• Analysed and designed workflow using Hive, MapReduce (Java), Perl.

• Implemented dataflow pipeline to handle up to billion ad-serving impressions per day.

CAFA Reporting

Description: CAFA system was basically developed as there were millions of mappings made for a, campaign to AdTag and each time as the property of sites/adtags are changed the number of mappings are disassociated with the campaign,which generate a tremendous amount of data & this data can be used for forecasting & insights for the publishers storing this data in mysql was not scalable .As we had 3 server having this data logged, using flume we pulled the data from all the 3 server and ingested in hadoop, it was partitioned by date & hour. Hourly data was rolled up once per day to make it daily & give insight to publishers.

Technologies Used: MapReduce (Java),Flume,hadoop.

Campaign Management & Reporting

Description: I have been working on Demand Portal(campaign management & reporting) which provides Demand Partners a platform to access performance analytics, forecast inventory, create and run campaigns and view violations in one place.

Technologies Used: Core Java, Servlets, Spring Framework, MyBatis, Shell Script, Mysql .

Violation Reporting

Description : As the publisher sites serves various types of ads on their sites it may be possible that some of the ads are irrelevant for the publisher which is called as violation or malwares which were reported in JIRA, but to capture all this actions it was not possible to do a manual intervention every time. Developed an automated framework for the same, plug-in for JIRA was developed which used to pull the malwares & violation from the JIRA system & import it to Mysql, also used to resolve the issues from the plug-in as the violation is resolved.

Technologies used: Core Java, Spring Framework, MyBatis, Shell Script, Mysql, JIRA Api.

Honors : Spot Award

PubConnect

Overview

IvbLive is a web based product. Basically this product is built to serve users to manage their IT resources in a secure, reliable and cost effective way. In the past few months they have developed their own cloud based software basically PaaS (Platform as a Service). This platform enables any organization or enterprise to manage their IT infrastructure in a secure, reliable and cost effective way This system also served the need of document management system it involved working in collaborative environment editing any document by more than on person etc.

eg: merging of a document with different versions. (version controlling)

Intellegent Search

Developed a Distributed Search Functionality For The Application

It involved sharding the indexes and running multiple indexer and readers on different machines. The module included the indexing of the documents and storing them on different Machine.

Implemented configuration of the system and starting the services at the server.

Distributed Architecture

The advantage of distributed architecture for search is that different indexer running on different machines is independent of each other. And the Reader also runs on different machine so if any indexer would stop it may fetch results from the existing indexed documents rather than getting stopped.

This functionality was developed Using

Technologies Used: Java, Springs framework, Lucene Api’s.(2.9.3).,Linux,Mysql, Mongo DB.
